After an initial chat with recruiter, I was presented with an online coding challenge. It was an easy algorithms question on binary trees. Had two sets of phone interviews which tested knowledge on my resume, data structures and algorithms and design skills. After sailing right through them, was invited for a full-day on-site interviews - I had four of them. The in-person interview were a bit difficult than the phone interviews - two of these were algorithms(focused mostly around binary search), one was a system design interview and the final was more of a hiring manager round which talked about my work and aspirations. Overall nice interview experience. I did not receive an offer.
