I had two interviews:

• One for the machine learning side.
• One for the programming side.

Unfortunately, I did not make it to the second round of interviews.

For the ML interview, there were some easy questions about general knowledge of ML, and one question about what I would do in realistic ML project scenarios.

For the programming interview, I was given a coding problem that was a modified version of the lowest common ancestor in an n-ary tree, which was pretty simple.

Both interviews concluded with questions about Amazon's leadership principles.

I believe I aced the technical part but fumbled the leadership principle part. I can't be sure, since Amazon does not provide feedback.

Find LCA in n-ary tree.

Questions about:

• A time series project scenario
• A project where the goal is to predict customer returns

Then more general questions about ML.

Questions about leadership principles.
