I had a 30 mins behavior interview which I think is the first round. They called ahead to schedule the time. It was a phone call interview that began with "Tell me about yourself". They also asked why you apply for this position and what you know about the company.

two rounds of interviews, one with hr and the second with the manager, lots of behaviour questions, asking your technical skills, etc. pretty straightforward. The entire interview lasted about 20 minutes.
