There's usually very little information from the recruiters on interview process or the groups that is taking the interview. Generally this info can be obtained from the interviewers.
There were 2 phone interviews, both last for about an hour. Most questions were generic about algorithms and data structures etc. Nothing specific on any language or OS.
After a long 3 week wait there was an invitation for in house interview. That too took 2 weeks to schedule, but no big deal.
The in house interview lasted for about 4 or so hours. There's some new wave of interviewing called behavioral interviews. I don't understand it, but I seriously doubt its working OR the interviews know what to ask and how to interpret. Of course I'm sure they are trained, but not everybody learns what the non-techie expects techies to learn.
