Initial call with the recruiter, followed by two technical rounds, and then a call with the hiring manager. The recruiter was very communicative and responsive throughout the process. The two technical rounds were similar, where you'd solve a problem with an engineer and they would have some follow-up questions. Everything went smoothly until I got to the hiring manager interview. He came across as annoyed/disinterested from the very start and had asked me what problems I had been asked during the technical rounds, as if he felt I shouldn't have been able to solve them. Throughout the conversation, it was clear to me that he did not value my experience. When I had asked him about any feedback or concerns towards the end of the call, he referred to a question that he had asked earlier that he didn't like the answer to. When I addressed it to add some context, he put his head down and started scribbling on his pad like he didn't want to hear it. I was so put off by the interview that I withdrew my candidacy following the call. I could not see myself thriving under that type of leadership. All that said, everyone else I dealt with during the process was great.
