Reject after accepting - what happens
What happens if I accept a Microsoft/Amazon offer and reject it later? I understand it's bad and I don't want to do it either, but I interned and for returning as FTE recruiter says that I'll be placed depending on open headcounts, and I'll know exact team placement couple months before joining means I would have to accept the offer before that. I don't want to sign up for something I am not passionate about.
Need info on blacklist policy especially for Amazon and Microsoft.
