TLDR: After interviewing with 12(!) people on 3 separate days they ghosted me, not rejected, just stopped answering emails.

I was contacted by Wombat about a remote developer position. I had a phone screen with a team leader, and was immediately invited to a full interview. The interview consisted of 6 rounds of panels from various teams, including some that had almost no relation to the position I applied for. In all I spent more than 7 hours interviewing with various people around the company over 3 days. I was told I would hear back with a decision within 10 days. For a month I followed up every week, and was told that no decision had been made. After that, my HR contact just disappeared from the face of the earth, no read receipts from e-mails, nothing. I never said anything rude, and even had others review my emails to make sure that I wasn't being aggressive or pushy.

I get it if they don't want to hire me, but using that much of my time, and then not having the courtesy to copy and paste a form rejection email speaks volumes about how they value people at Wombat/Proofpoint

They didn't do any 'whiteboard' style questions, they all centered around prior experience and things I had built in the past.
