Three interviews with increasingly senior employees. I thought the interviews went well, The third interviewer literally said at the end of the call that she thought I'd be a good addition to their team. Then silence. They ghosted me. I followed up with the initial HR contact and received no response. Extremely unprofessional and horribly frustrating. I sat next to my phone for weeks hoping for a call when they had already decided not to hire me and just didn't bother to tell me.
