Good place to start - Transaction Risk Investigator Amazon Employee Review

AWS has one of the most fun and interactive assessments upon applying and if you pass they almost instantly give you an interview with the recruiter.

I don't have any thus far

Really smart people, a lot of opportunity for growth, always encouraged to be innovative, think big, and create something new. Competitive salary and benefits with other major tech companies. 100% self motivating work environment. No dress code and 4 legged friends are welcome.

You have to be self motivated. NO ONE will hold your hand and tell you that you're doing a great job. If you need constant affirmations from management, this company isn't for you.
