Now that you know more about the roles and responsibilities of Amazon data science teams, here's a brief overview of how the interview process works.
Outlining the Interview Process of Amazon Data Scientist Position
Amazon has a fairly standard (if extensive) interview process for the data scientist position, from the initial phone call screening through the hiring manager interview, and finally the full day on-site interview.
Online Application & Phone Screening
After your online application and resume are submitted, there is an initial screening phone call with a recruiter. This is a short half-hour conversation where the recruiter goes over your resume and experiences, and then briefly explains the role, team, and team's relative position within the company.
Next up for the Amazon data scientist position is the technical screen, which will go more in-depth about your data experiences and technical expertise. This will include questions about statistics, coding, algorithms, and product design, with the data science coding questions being done over a shared code editor.
Full Day On-site Interview
After passing the technical screen, there is the full day on-site interview. There will be around 5 interviews split throughout the day, with a lunch break in between. The interviews will have a mix of behavioral and technical questions.
Note: the interviews will be virtual and the interview format may vary for the duration of the pandemic.
Types of Questions Asked During a Data Science Interview at Amazon
Interviews for the data scientist position at Amazon always include the typical questions about your background and experiences, commonly with many variations of "Tell me about a time where…"
- Where do you see yourself in 5 years?
- Describe a time when you had a difference of opinion with your colleagues.
- Tell me about a time when you had to work with incomplete data or information.

- How would you measure the impact of a business initiative?
- How would you describe the value proposition of AWS to the CIO of a company?
- What would you change on the Amazon website?

- Find the customer with the highest total order cost between a set of dates. Output their first name, total cost of their items, and the date.
- Given a table of purchases by date, calculate the month-over-month percentage change in revenue.
- What is the difference between a linked list and an array?
