It started with a phone interview the HR where they are mostly trying to gauge a sense of your personality; then that led to a panel interview; 2 rounds one being behavioral and the second being more technical. The important thing to do is to stay relaxed and keep a calm demeanor. I would start casual conversation with the interviewers that would last a while to the point where we had to get back on track and start asking me questions. I really enjoyed the process was very impressed by the company. I also gave them so advice about how they could improve their recruiting process from my university.
