First, I had a quick call from the recruiter to set up the interview. After that, I had three rounds. The first two were technical, and the third one was with the Hiring Manager, who also asked some technical questions. In the first round, I was asked to solve a coding assignment (which I did) and some questions on data structures. The second round also had two coding assignments, which were not that hard. The final round was with the hiring manager, who asked me some simple questions like OOP concepts and agile methodologies. I thought the interview went pretty well and was sure I'd get the job.
