- For the fist round, I don't remember what the OA questions were but they were relatively challenging. Hackerrank was the platform - Second round was chill. More like a chat on experience and why you should move onto the following round. - Final round: - The first question definitely an easy(for me). If you practice company tagged questions, you'll be good. - The second dsa question I thought was relatively easy (leetcode medium). Not in the company tagged questions but it wasn't nothing challenging. - System design wasn't anything difficult too. It was simple and also one of the questions you would find online in intro to system design. - Behavioral would be inline with the job description/how you fit in a team environment.
