Save up money and work at a risky pre-Series A startup. They'd kill to have an ex-FAANG employee who can design things from the ground up, lease a project to completion, and enjoy the systems they are building.

Recently left a small startup for Google and was recently talking with someone who thought I was going for promotion. I asked if I should, they then looked at my profile and said "You've only been here X long so they won't give it to you even if you deserve it."

Completely different world. Completely different mentality.
