Three rounds of technical and HR round. Technical questions consists of algorithms and Data structures as any tech company. you will be interviewed by the seniors for two rounds and principal for other round. Principal expects to be at a certain bar with the design related and architecture based questions.

I met with most of the team over the course of the day, all in all 7 hours on-site. We interviewed and had lunch in a conference room. There was some white-boarding of design, not coding, which was fun. The manager put some pre-written code up on a display and asked me to describe what was wrong with it, how to fix it, and followed up by some verbal question/answers on the whys and wherefores of things like threading. There were also questions that were more behavioral in nature, "how would you handle it if someone did this" types of questions. I also met with their technical project manager I guess so they could get a feel for how I'd react to the build/deployment and requirements-gathering processes. All in all the whole interview was somewhat challenging but very interesting.
