I applied through an employee referral. The process took 2 months. I interviewed at Amazon (Seattle, WA) in Feb 2016
Interview
There were just two phone interviews. The first interview was a mix of code test, behavior and statistical questions. The code test was super easy as long as you were proficient in summarizing data and doing basic statistical analysis, such as aggregation, estimating missing values and linear regression. The second one was much harder and no question was necessarily related with my resume. I felt it was conducted by a senior BIE or data scientist. They hoped you could consider the problem more thoroughly and in a creative way. Of course, they also asked statistical questions, but I feel that was the easiest part.

Question 1
If we want to know whether people like a product, is there any statistical problems you can see when the analysis is based on their behaviors on the websites?
How do you combine text information into our recommendation system?
How do you compare models by data visualization?
The interview process was smooth and conversational. The interviewer was calmly asking questions about my previous work experiences and listened patiently. He even gave me ample time to frame my answers.

Question 1
1. Tell me about your previous work experience.
2. Asked few SQL questions
The first interview is a technical phone interview that assesses your skills in SQL and Python, specifically data analysis with python. The interviewer pastes the description of an SQL problem on the code editor and asks you to write your answer while describing your thought process. They give you hints when you're stuck.

Could you tell me the steps involved in the data analysis process?
few rounds of interviews ranging between technical and conversational. Mostly in the form of " tell a story of time where ..." to show how you relate to amazon LPs
