I get 3-5 requests to interview from Amazon a week. I ignore most of them completely because I know too much about them. Guy I worked closely with at a certain cobbler in Beaverton Oregon you've probably heard of. He left for good reason and had lots of bad things to day. The managed to claw him back after about a year with "a huge pile of money" right after he had a kid.

Up front (before talking to the hiring manager) artificial coding challenge is a massive red flag, and I'll bail at that stage with most companies.

Last week I asked one of their spear fishers via LinkedIn if they're still doing that. She confirmed they are so I don't need to talk to them for a while.
