Three interviews, each with a director. All very standard technical questions. The interviewers were very nice and understanding but definitely critical of any incorrect answers. They did help steer me in the correct direction at some point, but only when I was already nearly there.

3 rounds, behavioral questions based on experiences and personal ideas. 3 different people trying to understand if you can be a good fit for the company. every round is a pass or fail and at the end they will eventually make their offer.
