recruiter call, discussion with hiring manager, home work assignment and then 4 rounds of interviews. Personally I found the process painful because when you give a homework assignment which takes 3-4 hrs to do it right (case based home work with 7+ questions), you expect your interviewers to spend more time on that plus have open mind plus provide their attention. There were two rounds, where the person was busy doing his own stuff and not giving you attention. One case, he was in Vietnam and just woke up and was busy checking his mails or whatever. Homework assignment which added 4 hrs on top of all the interview rounds, were discussed by one person who was trying to fill 1hr of allocated time by literally repeating himself.
