Initial process of the interview is a video interview, then the recruiter will send you links to 2 different supplementary questionnaires. If you make it through this round then they will fly you to Pittsburgh for 2 day event where you will do 3-4 interviews on the second day. If you make it through this round then you'll have last interview where you will meet up with the branch manager of the location you want to work.
The whole process was very laid back and the interviews are basically a get to know you kind of informal interviews. One thing I would point out is that during the first night of meet up, you should try to make impressions on many Managers as possible since the more managers approve of you, you will have a higher possibility of getting selected. Overall it was a great experience and they really take care of you when you are in Pittsburgh.
