I completed 4 interviews including a final interview. HR was unresponsive. Had no way of contacting other interviewers to follow up. I conducted a final interview where I completed a coding challenge with 3 other software engineers. Meaningless problem unrelated to the work. Despite this, the interview went well and I was told I would hear back from HR in less than a week. In fact I never heard back and was ghosted. The interview process took about 2 months and no one let me know the outcome. Additionally, the diversity of employees I spoke with was not the best.
