There are 3 Rounds of interview
The first one is coding questions about Data Structure and Algorithms. Basically, it's similar to leetcode.
The second one is ML Questions about machine learning and deep learning.
Project Questions about different projects
Well structured, first recruiter call, online coding test that involved SQL, python ( basic regression ) and statistics. The process was good with good feedback. They also check how well you can communicate.
