Three rounds of interviews with a panel interview at the end. The panel probably could've been cut shorter than it was, I met about eight people in total and it took a long time. Everyone was nice, but their reasoning for not offering the position made no sense. They had told me because I expressed interests in different areas of the company that they decided not to give me the offer. Seems like they were looking for someone who wasn't looking to grow but would sit in the same seat indefinitely.
