Hi msdostoevsky! I'm happy for your interview went well.
I applied for Neuroscience program, and to be honest I didn't like my interview that much, it had such an arrogant and aggressive tone
In my case, I was asked to elaborate on some points in my SOP - about project ideas rather than previous research experience.
Next, the interviewer started interrogating me in which papers had I read, on the topics of my interest. That was very confusing and I wasn't prepared for that kind of question - I read a lot of papers, and I don't keep a complete list of references in front of me all the time. He probably wanted me to pick up one paper and discuss it, but I couldn't quickly think of any I would remember in sufficient details. I managed to push out some random paper off the top of my head and told about it in a few sentences.
Next, I discussed some ideas for projects again, all in hurry and I really got feeling it was all in vain.
After the interview I've asked what chances of getting admitted are, and got a reply they have ~180 applications from internationals for only two spots, so it's better to have a plan B. However, the interviewer have found my interview "interesting". oh Thanks!
All in all, although the interviewer told me he likes my app, I got a perception of him trying to "catch" or drown me.
