Amazon Machine Learning Scientist interview questions

I applied and interviewed for an internship. Two rounds interview with similar style. Both contain coding and machine learning basic knowledge. And behavioral questions are also included. The coding is not hard, compared with the other technology companies. Machine learning knowledge depends on the specific position you apply for.

The process took about a month. After applying through LinkedIn I passed the screening and was sent a home exercise with a basic regression model. This was followed by a 1 hr phone interview, and two 1hr each skype interviews (one technical machine learning and one coding).
