Personally I wouldn't want to work for an employer who'd retroactively change my performance reviews. On the other hand, working for AWS is hardly any sort of panacea. Initially it'll feel good to be out of your current situation, but there's a reason why Amazon burns through so many people - and as a Seattleite, I've heard lots of bad stories. I suggest you consider other options assuming you can hold things together until hiring starts again Jan/Feb.
