In total, I underwent 1 written interview, 2 psychometric assessments, 7 video interviews and 2 take-home design tasks over the course of 4 months. After a final interview I was told that they would like to make an offer, I had a video discussion with an executive about the terms and was told that I would receive my formal written offer in the next week or so. Two weeks go by and I receive a short email explaining that they've rescinded my offer with little to no explanation. I pushed to understand why this had happened and was told that despite almost everyone involved in the process thus far wanting to hire me, someone/some process was blocking it and they could not reach a consensus. Never have I heard of a company where an executive can be confident about making an offer, extend a verbal offer, and then have it blocked. It's completely immoral for someone to make a verbal offer and then rescind it. Canonical, recruitment is always partly a gamble and god only knows how you manage to recruit anyone.

Very long, many many steps, in depth, asking questions from a long time ago in the past, but helps understand the company very very well. Need to speak to engineers, hiring mangers, etc. There's also a take-home task involved
