Had an interview today. It was pretty fun, and I really worried waaay too much for how it would be. 
. Good luck SKGUN11! I'm sure you'll do well! 
Thanks man, I hope you did great too! I also found it quite fun tbh! I talked a lot and tried to be a leader. My group was pretty good, they were friendly, fun and smart. The interviewer was really nice too. We talked for a while, and I asked a few questions! I wont spoil it either for the other people because it is unfair, however I can say, it is not at all hard or intimidating. What time were you? Did you complete the maths problem?
Yay nice stuff! I'm sure you will do super well SKGUN, you have the passion for science so all you have to do is express it 
Haha yeah, thanks. You have nothing to worry about, everyone there is friendly, just try to talk a lot and be a leader, but dont take over - haha! Try to talk to people whilst waiting at the beginning, it helps you feel for comfortable talking. Just acknowledge everyones thoughts and express you opinion as much as possible.
