Round 1 - Online coding test. Round 2 - Technical interview. Round 3 - Behavioural and HR. It was an on campus opportunity and I made it till round 2. In Round 1 there were 2 coding questions related to the role I applied. In Round 2 the interviewer asked about myself, projects and some Data structures and algorithms questions related to Trees + Dynamic Programming problem. I gave the optimal solution and clearly stated my approach to solve but couldn't code completely as it required logics of backtracking and DP. It was an hour long.

The interviewer started by introducing themselves and going over how the interview would run. I was then given a real-time coding problem to work through. There were also standard behavioral and cultural fit questions. At the end, I had time to ask my own questions about the job and the company.
