Initial phone call from a lead engineer, then on to a few interviews with other supervisors and HR. Skills test on technicalities specific to the position. Everyone was friendly and it wasn't a tense environment where they try to get to the limits of your knowledge - they just ask the questions relevant to your position and where you see yourself going in the future. The test has some pretty hard problems so maybe that's where they get a feel for your limits.

The process of the interview was really smooth, the interviwers are very nice. The first step is a Phone Call Interview reviewing your interpersonal skills and resume. Secondly, Video Interview focusing on Theoretical concepts. Lastly, an in person interview.
