There were three rounds of interviews with recruiter and managers followed by one final interview with executives. No assignments or briefings required as part of interviews. Overall process was around a month.

First round was a basic screening with an HR rep. I was invited to an on-site round with the Hiring Manager, another manager, and the lead. I don't remember the questions, but I remember that they were not hard. The interview was relatively easy. I received an offer, accepted, and worked there for about 2 years.
