Hi,
I got a totally unexpected call from a professor from a top 10 school. I was in the middle of some simulations, and I could not concentrate on the gravity of the conversation. The professor basically said I have to be 100% committed to join her group, then she will ask the department to send me an acceptance letter. I said I am 100% sure and that she was the first professor to call me and that I have applied to some other universities too (she knew already, had to put that in the application form). However, I think my tone was not 100% sure - as I said I just got an unexpected call. She said - no problem, go to my research page, search on the internet and email me. The conversation was just 3 min 50secs long and most of the time she talked about her group (no research talk). She said she was impressed by my qualifications and my application and her needs students like me. I emailed her 15 minutes later, and reiterated my commitment. This happened 1 day ago. However, she has not replied yet and I have not heard from the department also. You have figured by now that I am getting a little paranoid. Does this happen often? Does this mean the professor was just checking if I was ready to join or not before she makes her offer, i.e, am I basically in? Should I email her again? After that I checked her profile and found out she was the world leading authority in that field.......don't even talk about it, she is great!
