The interview process was daunting -- the agenda was unclear and the interviewer was called in from a different department with very little knowledge on the job that I was applying for. He also asked textbook questions and quizzed me like it was an exam. I was fine with it but felt that the interview process was not well thought through.

Very smooth and kinda average difficulty. but if you prepare well, all will be fine. There are tao interviewers from different departments. The interview takes around 1 and half hours.
