I applied through recruiter. First round of my interview was done by phone by a hiring manager, who was really nice. It took about 20 minutes. Then, I was invited to the on-site interview which was 3 hours (!) long and was very exhausting. I met 6 individuals, spent 30 minutes with each of them at 1-on-1 meetings. They were asking absolutely same questions, however, last two persons made the accent on behavior questions which i hate. The temperature in the conference room where the interview was held was very hot and there was no drinking water at the facility per the receptionist. I had severe headache by the end of the 2nd hour. Even though I haven't received a job offer, the overall experience was terrible and left bad aftertaste.

Phone screening with recruiter, phone interview with hiring manager, on site interview with a few people you will be working with. The on site interview will take about 3 hours. Look into SMART interview questions and think about how you will respond to behavioral questions.
