The interview process took place over three months. They started with the typical recruiter phone screening, which was describing the company, the role and covering basic benefits/potential salary ranges. Next was an on-site interview, which took place over four hours with four different people. They got back to me about a week later to say that they didn't want to hire me for the position I was interviewing for, but they had another one in mind. So I had two follow-up screening calls with additional people, and then another on-site interview that took three hours. I got lots of positive feedback and the hiring manager reached out to me at one point to tell me that he thought I was great and that due to summer scheduling, he was hoping I could hang tight for "a few days" while they made their decision between me and one other candidate. After that, they disappeared. For a month. I reached out countless times to ask whether they had made a decision, and after multiple attempts each time would hear back from the recruiter who would say things like "not yet, but we had great feedback about you" only to disappear for ages again. After such a promising and involved start, they sure disappeared fast. I finally heard, almost 3 months to the day after the first interview, that they offered the position to someone else. I honestly wasn't surprised at that point, having been ghosted for a month, but was annoyed that I had wasted three months and many hours on a company that couldn't even be considerate enough to tell me "thanks but no thanks".
