Multiple steps going over a great deal of time which should be addressed in the future. At least start with those that have the most chance of rejection. - Initial screening - Authoring of essay based on some very interesting questions (around 3-4 hours) - Aptitude and personality tests - Initial HR interview (30 minutes) - 3-4 interviews with engineering leadership (1 hour each) - Interview with CTO (1 hour) - Interview with VP of engineering (depends) - Interview with CEO (depends) Everything was fine during the first stages, I met some very interesting people and had some in depth engineering management and technology discussions. During the last interview, the interviewer was impatient and seemed to me that he wanted to end the interview as soon as possible. The questions were very vague, like pick a subject to talk about, something more in depth and other generalisms amounting to "impress me". He seemed bored the entire time. I did not expect to land the job as my backround is far from the open source community and I had an overall very positive experience up to the last interview.
