The recruiter called the day after I applied to talk about my resume. After the phone interview, I was invited on-site to go through a gauntlet of interviews that lasted for 45 minutes each. There were 6 technical and 2 non-technical interviews. Lunch was provided and I ate out with the recruiter and some other interviewers. Every interviewer seemed to be very busy but they were kind and tried not to rush the interviews. Although there were many interviews some of the interviews had overlapping technical questions so they were not too bad.
