The first phone call was a quick 20 minute call with their recruiter. Second was a panel interview with 3 people. The recruiters aren't very forthcoming regarding all the questions I asked that was related to the position so I highly advise you to ask all of you questions and confirm with the hiring manager instead. You may quickly realize you're getting conflicting information from different people and could avoid any last minute surprises while on the job.

I came up with 3 rounds of interviews. The 1st round was with HR that I have been asked personal questions, the 2nd round was with the hiring manager along with technical questions and the 3rd one was with the team a mixture of personal and technical questions.
