First you get a pre-screening call where you tell them a bit about yourself. After a few weeks, you're invited to an Open day where they tell you about the company, do group tech challenges and then you have an 8-minute interview where they ask you questions. Pros: - The interview is fun. You meet new people and the interviewers try to break the ice as much as possible. - They provide food and snacks. Cons: - The mob programming breaks the flow of a group. These are strangers, really, and now for a quarter of the time you cannot speak. It's hard to create a good group dynamic under those circumstances. Further, they don't make sure that everyone can code in the same language when put into a group. - The interview/open day is very long (9 hrs), but an interviewer only speaks to you directly for 8 minutes. - Depending on which interviewer you get, you get a drastically different experience. Vastly different questions are asked. I think if you did the effort to be there, they should give everyone the same effort back.
