First met with recruiters at a University Career Fair. Received a call from them a few weeks later and was asked a few questions over the phone for about 45 min. They were mostly behavioral/personality questions. Then I was called in to their hq for technical portion of the interview. I was also able to meet the other members of the team after the interview was over. The interview consisted of moderately difficult questions that made you think. But I was able to get the answers to a good portion of them after a few moments of pondering. Just be calm and think through it step by step. There were also some portions that you had to use mathematical formulas to aid in answering the questions. For example using math to solve how many testing problems need to be made to test a module etc.
