Some recommendations from a current student interviewer. This is just from my personal experiences interviewing and discussing with admissions committees.
1. Be prepared to answer WHY you want to do a PhD in general. If you are coming straight from undergraduate, be especially prepared to justify why you believe you are ready to enter directly into a PhD program instead of taking a year or two off.
2. Have justifications for why you applied to a specific institution and program. Being able to pinpoint specific faculty, resources, graduate outcomes, etc. all help show you are applying to a program for a particular reason and not just because it is ranked highly.
3. Be able to talk about your research clearly and concisely. If you do not know something, do not be afraid to say you do not know. I would rather have someone answer "I do not know" 10 times than try to make up an answer once. It is also helpful to be able to identify specific things you have taken away from each experience. Also, if you have multiple experiences, it is best to focus on the one you are most comfortable talking about rather than trying to give equal time to all of your research.
Above all, be enthusiastic about your own research, research in general, the program you are applying to, and pursuing a PhD. If you can talk about your research and genuinely seem excited about it, then that will come across to us and we will remember it more than if you can answer every single technical question flawlessly. It is okay if you are nervous and it is okay if you can't answer every question - it is not okay if you are just going through the motions.
4. For faculty interviews, don't worry about knowing their work inside and out. If you want, you can read a couple abstracts from their most recent papers + look at their lab websites, but anything beyond that is not expected.
5. Prepare questions! They can be general questions about graduate school, specific questions about a PIs research, etc., but do not just sit there blankly if you are asked if you have any further questions.
6. If you have a student interview in addition to faculty interviews, be forewarned that at many schools this interview will be weighted alongside your other interviews. This means you need to maintain professionalism and decorum.
7. You ARE being evaluated at all times, but 90% of the evaluation that goes into the final decision is done during the interviews. However, there are really only three things you can do that will get you immediately disqualified (and yes, I have seen each of these happen at least once): (1) Making sexist, racist, or homophobic remarks, (2) falling asleep during an interview, and (3) aggressively hitting on current students or PIs to the point of harassment. Every year, without fail, there are at least three recruits who do one of these things (usually #1 or #3) and are disqualified from consideration.
8. It is okay to drink alcohol if you are someone who likes to drink alcohol. It is okay to abstain from alcohol if you are someone who likes to abstain from alcohol. It is NOT okay to get belligerently drunk and make bigoted remarks or harass current students or other recruits. I would recommend knowing your limits and what type of drinker you are - we want you to have fun but try not to embarrass yourself. Believe it or not, we have accepted people who have gotten black out drunk and thrown up at recruitment parties, but do not put yourself into that situation.
9. Dress to impress for your interview day. A full suit is unnecessary for guys, but some nice slacks, a good button down, and a blazer will suit you well for all interviews. Gals, do not wear heels - you will seriously regret it. For the rest of the weekend, feel free to wear whatever is comfortable.
10. Have fun! All participating faculty and students go into the interview weekends trying to recruit EVERYONE. We want everyone to love our school and our program and want as many people to attend as possible. Talk to as many faculty and students as possible, be engaged, and generally look like you want to be there and you will find the biggest challenge will be deciding where you actually want to go from all of your options. Getting the interview is the hard part - we interview around 8-10% of applicants and accept around 75% of those interviewed. If you have gotten an interview, you have all the qualifications to get accepted - we just need to make sure that you look as good in person as you are on paper.
I hope this helps! I'm sure I'll be seeing a few of you in the coming months.

Since you are Cellular and Molecular Biology, I think this response I wrote on the Biology forum will help:
A couple additional answers to your questions from my own experience as an interviewee and interviewer:
1. You don't have to prepare incredibly compelling questions for graduate students and faculty, just having anything is a positive in their eyes. But if you want to get a good glimpse into what they think, there are a few questions you should try to ask if appropriate.
For graduate students, you should ask about:
Their thoughts - both positive AND negative - on the program (such as the BBS program), institution (such as Harvard), and the city (such as Cambridge/Boston) What they do outside of science/lab What opportunities are available to graduate students - this includes teaching, internships, non-traditional paths, etc. What a typical day in lab is like for them - this will vary student to student and lab to lab, but can be revealing about the culture at an institution If there is anything else they wished they had known before starting graduate school (in general or in that specific PhD program) For faculty, you should ask about:
What they believe the greatest strengths and weaknesses are of the institution The research environment at the institution - especially in regards to collaboration (a lot of PIs love to talk to about how collaborative they are/their university is) Specific questions about their research (if you have any) Their expectations for a graduate student/what an ideal graduate student is to them If there is anything that they can talk about other than the research that makes the program/institution unique. If you look at graduate school interview prep websites, there will be a lot of "recommended" questions that include asking about graduation outcomes, fellowships, time to graduation, publishing, etc. It is okay to ask questions such as these, but a lot of this information will be covered in the introduction/orientation each program gives. In my opinion, you are better suited to ask questions such as those listed above.
2. The most basic biomedical PhD interview weekend is structured over 3 or 4 days:
Thursday: Arrive + welcome dinner Friday and Saturday: Interviews, research talks and poster sessions, dinner with faculty one night and dinner with students another night, something fun in the city one day, and a student-hosted party or bar night Sunday: Departure This gives you a lot of time to learn about science, talk to current students and faculty, get a glimpse of what the city is like, and make an impression. The actual events will vary interview to interview, but this is what the majority of major research institutions do.
3. If you talk to a lot of graduate students and faculty and are truly enthusiastic to learn about a program/institution (and science in general), you will come out of a weekend with everything you need to make a good decision. You most likely won't like every interview, but you will start to internally rank them over the course of interview season. Try to go into each interview with an open mind too!
Sorry this is so lengthy - I hope it helps though!

If you have gotten an interview, you have all the qualifications to get accepted - we just need to make sure that you look as good in person as you are on paper.

A couple tidbits from an interviewer to hopefully make that dread go away (at least partially!):
1. It is 100% okay to be awkward during a one-on-one interview. In fact, many times the interviewer themselves will be feeling more awkward than you do. As long as you are able to talk enthusiastically about your science and are sincere in doing so, you will be fine. There are scientists at all levels from PhD students to Nobel Laureates who are awkward, and the interview process itself is awkward and uncomfortable in general!
2. I have never heard of someone being rejected post-interview because they are awkward or uncomfortable or nervous in one-on-one conversations. The most common reasons that pop up would be you cannot actually talk about the research you listed in your SOP, you are not friendly or even remotely cordial with the interviewer, you say something that is an immediate red flag (such as questioning why you want to do a PhD or saying something racist), or you do not show enthusiasm for pursuing a PhD, science, etc.
3. We love it when an interviewee really gets excited about something during an interview. It can be your research, the PIs research, a hobby, etc. If you can latch on to something that excites you, you can really cut through that awkwardness. If it is something in your own research, that is especially beneficial as you will be able to bring it up in each interview.
4. If you are a coffee drinker, do not drink a ton of coffee before you interviews. It sounds weird, but that can really exacerbate the nerves before a one-on-one interview.
5. The interviews themselves are more like conversations. There isn't a preset list of questions that we ask in a row. I have three questions that I will always try to ask and let the conversation develop from there. It doesn't always go that way, but even with the most awkward interviewees (think someone shaking and barely able to speak they are so nervous) I find you can always cut through any awkwardness as long as the interviewee actually wants to be there and has an interest in doing a PhD at that institution.
One final thing: Don't get discouraged if your first PI interview doesn't go 100% perfect. My first PI interview I attended years ago went truly horrifically (I developed a stutter I was so nervous), but I still managed to get into (and attend) that institution. We expect you to be nervous at first. Every PI interview you do, you will get better and better at it. A lot of the times, in the beginning we ask the recruits how they feel and they are universally terrified, whereas by the end of the the first set of interviews they find them relatively relaxing and sometimes even fun.
I hope this helps a little!

Practice 1 minute, 3 minute, and 5 minute summaries of your research. Pick one project and be able to distill it down to three different time lengths and you will have zero problem! Additionally, identify what really excites you about your research and try to focus whatever you say around that.

Since you are Cellular and Molecular Biology, I think this response I wrote on the Biology forum will help:

At this level, the Ivy League name does not matter much at all. The success and prestige of individual programs at the universities and individual scientists matter significantly more. In terms of scientific prestige, I would put UPenn and Michigan at the same level as I really don't think you can go wrong with either in terms of science.

A couple additional answers to your questions from my own experience as an interviewee and interviewer:
1. You don't have to prepare incredibly compelling questions for graduate students and faculty, just having anything is a positive in their eyes. But if you want to get a good glimpse into what they think, there are a few questions you should try to ask if appropriate.
For graduate students, you should ask about:
Their thoughts - both positive AND negative - on the program (such as the BBS program), institution (such as Harvard), and the city (such as Cambridge/Boston) What they do outside of science/lab What opportunities are available to graduate students - this includes teaching, internships, non-traditional paths, etc. What a typical day in lab is like for them - this will vary student to student and lab to lab, but can be revealing about the culture at an institution If there is anything else they wished they had known before starting graduate school (in general or in that specific PhD program) For faculty, you should ask about:
What they believe the greatest strengths and weaknesses are of the institution The research environment at the institution - especially in regards to collaboration (a lot of PIs love to talk to about how collaborative they are/their university is) Specific questions about their research (if you have any) Their expectations for a graduate student/what an ideal graduate student is to them If there is anything that they can talk about other than the research that makes the program/institution unique. If you look at graduate school interview prep websites, there will be a lot of "recommended" questions that include asking about graduation outcomes, fellowships, time to graduation, publishing, etc. It is okay to ask questions such as these, but a lot of this information will be covered in the introduction/orientation each program gives. In my opinion, you are better suited to ask questions such as those listed above.
2. The most basic biomedical PhD interview weekend is structured over 3 or 4 days:
Thursday: Arrive + welcome dinner Friday and Saturday: Interviews, research talks and poster sessions, dinner with faculty one night and dinner with students another night, something fun in the city one day, and a student-hosted party or bar night Sunday: Departure This gives you a lot of time to learn about science, talk to current students and faculty, get a glimpse of what the city is like, and make an impression. The actual events will vary interview to interview, but this is what the majority of major research institutions do.
3. If you talk to a lot of graduate students and faculty and are truly enthusiastic to learn about a program/institution (and science in general), you will come out of a weekend with everything you need to make a good decision. You most likely won't like every interview, but you will start to internally rank them over the course of interview season. Try to go into each interview with an open mind too!
Sorry this is so lengthy - I hope it helps though!

Some recommendations from a current student interviewer. This is just from my personal experiences interviewing and discussing with admissions committees.
1. Be prepared to answer WHY you want to do a PhD in general. If you are coming straight from undergraduate, be especially prepared to justify why you believe you are ready to enter directly into a PhD program instead of taking a year or two off.
2. Have justifications for why you applied to a specific institution and program. Being able to pinpoint specific faculty, resources, graduate outcomes, etc. all help show you are applying to a program for a particular reason and not just because it is ranked highly.
3. Be able to talk about your research clearly and concisely. If you do not know something, do not be afraid to say you do not know. I would rather have someone answer "I do not know" 10 times than try to make up an answer once. It is also helpful to be able to identify specific things you have taken away from each experience. Also, if you have multiple experiences, it is best to focus on the one you are most comfortable talking about rather than trying to give equal time to all of your research.
Above all, be enthusiastic about your own research, research in general, the program you are applying to, and pursuing a PhD. If you can talk about your research and genuinely seem excited about it, then that will come across to us and we will remember it more than if you can answer every single technical question flawlessly. It is okay if you are nervous and it is okay if you can't answer every question - it is not okay if you are just going through the motions.
4. For faculty interviews, don't worry about knowing their work inside and out. If you want, you can read a couple abstracts from their most recent papers + look at their lab websites, but anything beyond that is not expected.
5. Prepare questions! They can be general questions about graduate school, specific questions about a PIs research, etc., but do not just sit there blankly if you are asked if you have any further questions.
6. If you have a student interview in addition to faculty interviews, be forewarned that at many schools this interview will be weighted alongside your other interviews. This means you need to maintain professionalism and decorum.
7. You ARE being evaluated at all times, but 90% of the evaluation that goes into the final decision is done during the interviews. However, there are really only three things you can do that will get you immediately disqualified (and yes, I have seen each of these happen at least once): (1) Making sexist, racist, or homophobic remarks, (2) falling asleep during an interview, and (3) aggressively hitting on current students or PIs to the point of harassment. Every year, without fail, there are at least three recruits who do one of these things (usually #1 or #3) and are disqualified from consideration.
8. It is okay to drink alcohol if you are someone who likes to drink alcohol. It is okay to abstain from alcohol if you are someone who likes to abstain from alcohol. It is NOT okay to get belligerently drunk and make bigoted remarks or harass current students or other recruits. I would recommend knowing your limits and what type of drinker you are - we want you to have fun but try not to embarrass yourself. Believe it or not, we have accepted people who have gotten black out drunk and thrown up at recruitment parties, but do not put yourself into that situation.
9. Dress to impress for your interview day. A full suit is unnecessary for guys, but some nice slacks, a good button down, and a blazer will suit you well for all interviews. Gals, do not wear heels - you will seriously regret it. For the rest of the weekend, feel free to wear whatever is comfortable.
10. Have fun! All participating faculty and students go into the interview weekends trying to recruit EVERYONE. We want everyone to love our school and our program and want as many people to attend as possible. Talk to as many faculty and students as possible, be engaged, and generally look like you want to be there and you will find the biggest challenge will be deciding where you actually want to go from all of your options. Getting the interview is the hard part - we interview around 8-10% of applicants and accept around 75% of those interviewed. If you have gotten an interview, you have all the qualifications to get accepted - we just need to make sure that you look as good in person as you are on paper.

A couple tidbits from an interviewer to hopefully make that dread go away (at least partially!):
1. It is 100% okay to be awkward during a one-on-one interview. In fact, many times the interviewer themselves will be feeling more awkward than you do. As long as you are able to talk enthusiastically about your science and are sincere in doing so, you will be fine. There are scientists at all levels from PhD students to Nobel Laureates who are awkward, and the interview process itself is awkward and uncomfortable in general!
2. I have never heard of someone being rejected post-interview because they are awkward or uncomfortable or nervous in one-on-one conversations. The most common reasons that pop up would be you cannot actually talk about the research you listed in your SOP, you are not friendly or even remotely cordial with the interviewer, you say something that is an immediate red flag (such as questioning why you want to do a PhD or saying something racist), or you do not show enthusiasm for pursuing a PhD, science, etc.
3. We love it when an interviewee really gets excited about something during an interview. It can be your research, the PIs research, a hobby, etc. If you can latch on to something that excites you, you can really cut through that awkwardness. If it is something in your own research, that is especially beneficial as you will be able to bring it up in each interview.
4. If you are a coffee drinker, do not drink a ton of coffee before you interviews. It sounds weird, but that can really exacerbate the nerves before a one-on-one interview.
5. The interviews themselves are more like conversations. There isn't a preset list of questions that we ask in a row. I have three questions that I will always try to ask and let the conversation develop from there. It doesn't always go that way, but even with the most awkward interviewees (think someone shaking and barely able to speak they are so nervous) I find you can always cut through any awkwardness as long as the interviewee actually wants to be there and has an interest in doing a PhD at that institution.
One final thing: Don't get discouraged if your first PI interview doesn't go 100% perfect. My first PI interview I attended years ago went truly horrifically (I developed a stutter I was so nervous), but I still managed to get into (and attend) that institution. We expect you to be nervous at first. Every PI interview you do, you will get better and better at it. A lot of the times, in the beginning we ask the recruits how they feel and they are universally terrified, whereas by the end of the the first set of interviews they find them relatively relaxing and sometimes even fun.
I hope this helps a little!

Some recommendations from a current student interviewer. This is just from my personal experiences interviewing and discussing with admissions committees.
1. Be prepared to answer WHY you want to do a PhD in general. If you are coming straight from undergraduate, be especially prepared to justify why you believe you are ready to enter directly into a PhD program instead of taking a year or two off.
2. Have justifications for why you applied to a specific institution and program. Being able to pinpoint specific faculty, resources, graduate outcomes, etc. all help show you are applying to a program for a particular reason and not just because it is ranked highly.
3. Be able to talk about your research clearly and concisely. If you do not know something, do not be afraid to say you do not know. I would rather have someone answer "I do not know" 10 times than try to make up an answer once. It is also helpful to be able to identify specific things you have taken away from each experience. Also, if you have multiple experiences, it is best to focus on the one you are most comfortable talking about rather than trying to give equal time to all of your research.
Above all, be enthusiastic about your own research, research in general, the program you are applying to, and pursuing a PhD. If you can talk about your research and genuinely seem excited about it, then that will come across to us and we will remember it more than if you can answer every single technical question flawlessly. It is okay if you are nervous and it is okay if you can't answer every question - it is not okay if you are just going through the motions.
4. For faculty interviews, don't worry about knowing their work inside and out. If you want, you can read a couple abstracts from their most recent papers + look at their lab websites, but anything beyond that is not expected.
5. Prepare questions! They can be general questions about graduate school, specific questions about a PIs research, etc., but do not just sit there blankly if you are asked if you have any further questions.
6. If you have a student interview in addition to faculty interviews, be forewarned that at many schools this interview will be weighted alongside your other interviews. This means you need to maintain professionalism and decorum.
7. You ARE being evaluated at all times, but 90% of the evaluation that goes into the final decision is done during the interviews. However, there are really only three things you can do that will get you immediately disqualified (and yes, I have seen each of these happen at least once): (1) Making sexist, racist, or homophobic remarks, (2) falling asleep during an interview, and (3) aggressively hitting on current students or PIs to the point of harassment. Every year, without fail, there are at least three recruits who do one of these things (usually #1 or #3) and are disqualified from consideration.
8. It is okay to drink alcohol if you are someone who likes to drink alcohol. It is okay to abstain from alcohol if you are someone who likes to abstain from alcohol. It is NOT okay to get belligerently drunk and make bigoted remarks or harass current students or other recruits. I would recommend knowing your limits and what type of drinker you are - we want you to have fun but try not to embarrass yourself. Believe it or not, we have accepted people who have gotten black out drunk and thrown up at recruitment parties, but do not put yourself into that situation.
9. Dress to impress for your interview day. A full suit is unnecessary for guys, but some nice slacks, a good button down, and a blazer will suit you well for all interviews. Gals, do not wear heels - you will seriously regret it. For the rest of the weekend, feel free to wear whatever is comfortable.
10. Have fun! All participating faculty and students go into the interview weekends trying to recruit EVERYONE. We want everyone to love our school and our program and want as many people to attend as possible. Talk to as many faculty and students as possible, be engaged, and generally look like you want to be there and you will find the biggest challenge will be deciding where you actually want to go from all of your options. Getting the interview is the hard part - we interview around 8-10% of applicants and accept around 75% of those interviewed. If you have gotten an interview, you have all the qualifications to get accepted - we just need to make sure that you look as good in person as you are on paper.
I hope this helps! I'm sure I'll be seeing a few of you in the coming months.
 

Nothing impresses us more than if you can give a mini-chalk talk during an interview and do it clearly and concisely. I second the "do not bring handouts" sentiment. I do not personally mind, but I know a few PIs who look on this unfavorably.

After having my first interviews this weekend, this is what I came away with:
I didn't really need to know much about the faculty's research, just the general idea of what their research focuses on. A few told me about their research, but the interview was focused on my experience, and I didn't really get the opportunity to comment on their research, because it was usually toward the end of the interview.
So long as we were talking the entire 30 mins, it was a successful interview. Either I went on and on about my research experience, answering their questions throughout, or we sparked a random conversation about almost irrelevant subjects and kept on that track the whole time. With one guy I talked about the difficulties of getting patients into studies for half the time (I do molecular biology research, not anything clinical). Whenever I felt a lull in the conversation coming, I thought of a question to ask. With one we just spoke about my general interests, including non-science related interests.
Almost every interviewer asked me to tell them about my research experience. In one of the first ones, I decided to start from the very beginning of my lab experience (5 years ago), which I quickly realized was a bad idea. It was my earliest experience, and although I know the big picture of the experiment and my part in it, I don't have a firm grasp on everything, so I couldn't answer a few of the questions about it. What I did in the rest of my interviews was immediately bring up my most recent, most significant research experience, and reference my prior experiences where appropriate.
There was a panel interview for 20 mins with the entire admissions committee (6 people). It was intimidating at first, but actually ended up being the least stressful interview. I just talked about my research the whole time and they asked questions about it throughout.
Finally, wear comfortable shoes. They don't have to be the most stylish, so long as they're formal enough and you can spend a day in them walking up and down hills (my interviews weren't all on the same side of campus).
The director of the program/head of the admissions committee told me I did really well, so I'm coming away from it assuming I did something right.

Since you are Cellular and Molecular Biology, I think this response I wrote on the Biology forum will help:
A couple additional answers to your questions from my own experience as an interviewee and interviewer:
1. You don't have to prepare incredibly compelling questions for graduate students and faculty, just having anything is a positive in their eyes. But if you want to get a good glimpse into what they think, there are a few questions you should try to ask if appropriate.
For graduate students, you should ask about:
Their thoughts - both positive AND negative - on the program (such as the BBS program), institution (such as Harvard), and the city (such as Cambridge/Boston) What they do outside of science/lab What opportunities are available to graduate students - this includes teaching, internships, non-traditional paths, etc. What a typical day in lab is like for them - this will vary student to student and lab to lab, but can be revealing about the culture at an institution If there is anything else they wished they had known before starting graduate school (in general or in that specific PhD program) For faculty, you should ask about:
What they believe the greatest strengths and weaknesses are of the institution The research environment at the institution - especially in regards to collaboration (a lot of PIs love to talk to about how collaborative they are/their university is) Specific questions about their research (if you have any) Their expectations for a graduate student/what an ideal graduate student is to them If there is anything that they can talk about other than the research that makes the program/institution unique. If you look at graduate school interview prep websites, there will be a lot of "recommended" questions that include asking about graduation outcomes, fellowships, time to graduation, publishing, etc. It is okay to ask questions such as these, but a lot of this information will be covered in the introduction/orientation each program gives. In my opinion, you are better suited to ask questions such as those listed above.
2. The most basic biomedical PhD interview weekend is structured over 3 or 4 days:
Thursday: Arrive + welcome dinner Friday and Saturday: Interviews, research talks and poster sessions, dinner with faculty one night and dinner with students another night, something fun in the city one day, and a student-hosted party or bar night Sunday: Departure This gives you a lot of time to learn about science, talk to current students and faculty, get a glimpse of what the city is like, and make an impression. The actual events will vary interview to interview, but this is what the majority of major research institutions do.
3. If you talk to a lot of graduate students and faculty and are truly enthusiastic to learn about a program/institution (and science in general), you will come out of a weekend with everything you need to make a good decision. You most likely won't like every interview, but you will start to internally rank them over the course of interview season. Try to go into each interview with an open mind too!
Sorry this is so lengthy - I hope it helps though!

Some recommendations from a current student interviewer. This is just from my personal experiences interviewing and discussing with admissions committees.
1. Be prepared to answer WHY you want to do a PhD in general. If you are coming straight from undergraduate, be especially prepared to justify why you believe you are ready to enter directly into a PhD program instead of taking a year or two off.
2. Have justifications for why you applied to a specific institution and program. Being able to pinpoint specific faculty, resources, graduate outcomes, etc. all help show you are applying to a program for a particular reason and not just because it is ranked highly.
3. Be able to talk about your research clearly and concisely. If you do not know something, do not be afraid to say you do not know. I would rather have someone answer "I do not know" 10 times than try to make up an answer once. It is also helpful to be able to identify specific things you have taken away from each experience. Also, if you have multiple experiences, it is best to focus on the one you are most comfortable talking about rather than trying to give equal time to all of your research.
Above all, be enthusiastic about your own research, research in general, the program you are applying to, and pursuing a PhD. If you can talk about your research and genuinely seem excited about it, then that will come across to us and we will remember it more than if you can answer every single technical question flawlessly. It is okay if you are nervous and it is okay if you can't answer every question - it is not okay if you are just going through the motions.
4. For faculty interviews, don't worry about knowing their work inside and out. If you want, you can read a couple abstracts from their most recent papers + look at their lab websites, but anything beyond that is not expected.
5. Prepare questions! They can be general questions about graduate school, specific questions about a PIs research, etc., but do not just sit there blankly if you are asked if you have any further questions.
6. If you have a student interview in addition to faculty interviews, be forewarned that at many schools this interview will be weighted alongside your other interviews. This means you need to maintain professionalism and decorum.
7. You ARE being evaluated at all times, but 90% of the evaluation that goes into the final decision is done during the interviews. However, there are really only three things you can do that will get you immediately disqualified (and yes, I have seen each of these happen at least once): (1) Making sexist, racist, or homophobic remarks, (2) falling asleep during an interview, and (3) aggressively hitting on current students or PIs to the point of harassment. Every year, without fail, there are at least three recruits who do one of these things (usually #1 or #3) and are disqualified from consideration.
8. It is okay to drink alcohol if you are someone who likes to drink alcohol. It is okay to abstain from alcohol if you are someone who likes to abstain from alcohol. It is NOT okay to get belligerently drunk and make bigoted remarks or harass current students or other recruits. I would recommend knowing your limits and what type of drinker you are - we want you to have fun but try not to embarrass yourself. Believe it or not, we have accepted people who have gotten black out drunk and thrown up at recruitment parties, but do not put yourself into that situation.
9. Dress to impress for your interview day. A full suit is unnecessary for guys, but some nice slacks, a good button down, and a blazer will suit you well for all interviews. Gals, do not wear heels - you will seriously regret it. For the rest of the weekend, feel free to wear whatever is comfortable.
10. Have fun! All participating faculty and students go into the interview weekends trying to recruit EVERYONE. We want everyone to love our school and our program and want as many people to attend as possible. Talk to as many faculty and students as possible, be engaged, and generally look like you want to be there and you will find the biggest challenge will be deciding where you actually want to go from all of your options.

If you have gotten an interview, you have all the qualifications to get accepted - we just need to make sure that you look as good in person as you are on paper.

MIT Biology is known as one of the more competitive programs to get accepted post-interview. I don't have any information about this year, but 2014 post-interview acceptance rate was around 50%. It will vary year to year, however, due to previous class size, funding availability, quality of applicants, etc. but I would assume it is in the 40-60% range.

It is okay if you are nervous and it is okay if you can't answer every question - it is not okay if you are just going through the motions.
4. For faculty interviews, don't worry about knowing their work inside and out. If you want, you can read a couple abstracts from their most recent papers + look at their lab websites, but anything beyond that is not expected.
5. Prepare questions! They can be general questions about graduate school, specific questions about a PIs research, etc., but do not just sit there blankly if you are asked if you have any further questions.
6. If you have a student interview in addition to faculty interviews, be forewarned that at many schools this interview will be weighted alongside your other interviews. This means you need to maintain professionalism and decorum.
7. You ARE being evaluated at all times, but 90% of the evaluation that goes into the final decision is done during the interviews. However, there are really only three things you can do that will get you immediately disqualified (and yes, I have seen each of these happen at least once): (1) Making sexist, racist, or homophobic remarks, (2) falling asleep during an interview, and (3) aggressively hitting on current students or PIs to the point of harassment. Every year, without fail, there are at least three recruits who do one of these things (usually #1 or #3) and are disqualified from consideration.
8. It is okay to drink alcohol if you are someone who likes to drink alcohol. It is okay to abstain from alcohol if you are someone who likes to abstain from alcohol. It is NOT okay to get belligerently drunk and make bigoted remarks or harass current students or other recruits. I would recommend knowing your limits and what type of drinker you are - we want you to have fun but try not to embarrass yourself. Believe it or not, we have accepted people who have gotten black out drunk and thrown up at recruitment parties, but do not put yourself into that situation.
9. Dress to impress for your interview day. A full suit is unnecessary for guys, but some nice slacks, a good button down, and a blazer will suit you well for all interviews. Gals, do not wear heels - you will seriously regret it. For the rest of the weekend, feel free to wear whatever is comfortable.
10. Have fun! All participating faculty and students go into the interview weekends trying to recruit EVERYONE. We want everyone to love our school and our program and want as many people to attend as possible. Talk to as many faculty and students as possible, be engaged, and generally look like you want to be there and you will find the biggest challenge will be deciding where you actually want to go from all of your options. Getting the interview is the hard part - we interview around 8-10% of applicants and accept around 75% of those interviewed. If you have gotten an interview, you have all the qualifications to get accepted - we just need to make sure that you look as good in person as you are on paper.
I hope this helps! I'm sure I'll be seeing a few of you in the coming months.
