I had a pre-interview and a 1st round interview with a partner starting his own team. The calls went great and the manager personally requested a second call. I followed up after the call, I followed up with the pre-interviewer 1 week later, I followed up with the manager 2 weeks later, and I followed up with both of them 3 weeks later. Fully ghosted me, very unprofessional. Not even one sentence saying we are moving in another direction.
