Applied online, had phone screen with recruiter, then 4 half hour interviews with peers, hiring manager and peer manager. After this stage, I was ghosted by both HR and the other interviewers. I attempted to email and phone HR and didn't receive a response and also attempted to email and phone 2 of the interviewers and didn't receive a response. At the very least, a company should have the courtesy to reach out to candidates who interviewed even if they weren't selected. I would never want to work for this organization.
