Lots of interviews. 1 initial phone screen, followed by 2 technical phone screens. Face to face interview included 6 one on one interviews, a presentation, and an engineering test (fundamental questions. Not difficult). 2 further highly technical phone interviews with the VP prior to offer.

First there is a phone screening, next there are interviews with engineers and managers, then finally there are in-person interviews. In the final interviews you need to give an in-depth technical presentation on a project you have worked on.
