I had two rounds.

In the first round, the interviewer was really nice and made the experience comfortable, not stressful. Since my subproject involved machine learning, they asked related questions, such as how I would retrieve specific values (x, y, z) from a dataset, and even touched on some terminology.

I also had to explain the model I used and code parts of it. Then, we moved to technical questions, including:

• A HashMap-related problem
• Tree traversal (in-order, post-order)
• Some sorting logic

The second round featured a single coding question.

I was later waitlisted and eventually informed they had selected other candidates.

In-order tree traversal with a twist.
