I went through a screen call and 4 rounds, each with progressively higher-level people. After each interview, I did 15-minute debrief calls with the recruiter. There was also a personality test. During the process, interviewers were nice and a few even connected with me on LinkedIn. Two of my four interviews were canceled and rescheduled due to conflicts on their end. After a time period of 2.5 months, I was ghosted, no response to multiple follow-ups asking for a status update.
