There were 2 video interviews. The first was based on optimization questions and the second one was a technical interview which had 2 codes based on data manipulation and 2 behavioral questions .
I applied through an employee referral. The process took 1 day. I interviewed at Amazon in Mar 2018
Interview
Two phone calls with one asking about past projects and the other asking two of the Amazon leadership principles. The process was quick and non-technical for me, I'm guessing because I had another pending offer and it was just for an internship, not full-time position. Also manager was non-technical and the other interviewer was a SDE and not data scientist.
