A series of phone calls and an on-site interview with the firm's leadership. The calls were mostly behaviorally based at first. As I advanced in the process, I grew to really like the leadership for the team I was referred to. I was then advanced to an on-site final round. I met with the firm's senior leadership, and one of them was a total tool. I learned later on that there was no real role for me at the company, and they were wasting my time - interviewing me IN CASE they got additional clientele, which they didn't. They then attempted to peddle me out as a contract candidate to their clients to at least try to make some money off me- which is something I told them I was explicitly against on the first call. Super unprofessional and dishonest, I told them I was no longer interested and pulled myself out of the process.
