Amazon Data Scientist interview questions

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 .

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.
