The process started with a recruiter call. She asked me basic questions regarding the job requirements and experience, why I was interested etc., Then she setup phone interview with the hiring manager which was easy and just consisted of questions about my background. He then scheduled me for three different rounds with other people in their team and a senior recruiter. They were super nice people and I felt very comfortable answering their questions. Finally I had another round with the hiring manager again in which it looked like he touched on questions he forgot about and in this case were most important and difficult to answer, all were technical questions related to the requirements for the job.
