There are 2 rounds in total. The first round has an extremely easy sql problem (group by + aggregation) + LP, and the second round has machine learning basics + LP.
It was easy. There were some behavioral questions but you will do great. I had 2 different people interview me, but they were very nice and accommodating. Amazon is a great place to work and I think that everyone should get a chance there.
I applied online. I interviewed at Amazon (Seattle, WA)
Interview
Had an online assessment and technical interview (~45 minutes). Relatively straightforward interview process. Faster turnaround than other companies I interviewed with. There might have also been a personality assessment, I don't recall super clearly.
