Had one phone interview and one in-person interview. The overall process took more than a month. People were generally friendly even though most of them seemed totally unprofessional. Some of them didn't even show up as scheduled without any explanation. The good thing is the pay for all your travel expenses and you stay in a nice hotel.

Question 1
Most of the questions were about my experience and things I did in grad school. not very hard but not very interesting either.
