There were 2 rounds
In first round I was asked some basic DSA questions and about my previous experiences and some basic maths related problems.
After a day I got a call from the hr that I have been selected for round 2 of the interview process .
Round 2 was more difficult and comprised of questions from the core cs subjects and also there were 2 medium level DSA questions and one Database Schema question.
After a day I got a call that I have been selected for the role and some basic discussion with the hr was done.
