Three rounds:

1. Phone interview
2. 1:1 Technical Interview
3. 1:1 Technical and Competency Interview

The phone interview focused on questions on Python (preferred language of the role and my current language), data structures, concurrency, and databases. It also covered soft skills and experience required for the role.

The second round was a 1:1 on-paper OO Design and problem-solving session.

The third round was the same as the second round but with more emphasis on soft skills.

Questions ranging from data structures and algorithms, OO design, on-paper programming question solving, and verbal technical questions.
