Amazon Data Scientist interview questions

Made contact with HR, several days later had telephone technical interview. They were clearly wanting a Software Engineer instead of a Data Scientist since my interviewer knew very little about Statistics or data science and only asked me CS questions. My interviewer also spent about 10 minutes discussing politics, which made me very uncomfortable.

2 phone interviews and 1 onsite interview and the onsite interview includes 5 small interviews with different people. Called out of the blue, asked if I'd be interested in interviewing. Still not entirely sure how they got my name. Had first phone interview the next week, asked no personal questions, all technical in nature. Total of 3 phone interviews and an in-person trip out to Seattle.
