There were 2 interviews and 1 teamwork task. The 1st interview was a 5 minute presentation about yourself and the other one was a 20 minutes interview specific on the position you wish to apply for.

First an online test, then a phone interview, and lastly a physical interview (+ technical paper test). Quite difficult interviews compared to the average. But very friendly people. You can tell the work environment is nice. They are looking for good fitting personalities, not necessarily super technical. They seem to offer a good work-life balance.
