I was working for a FAANG company and had negotiated internally with another department for a job which I would have been perfect for. My management chain veto’d the transfer, which was the day I decided to quit. I started looking for opportunities outside that company, and within six months had moved on to a job with significantly more responsibility than my original or other routes within the FAANG. Companies that prevent internal transfer turn them into external transfers.
