2/4 rounds i went, each round was eliminatory, first round was technical, majorly asked CN, OS question, 2 DSA maybe because we had some time left. DSA question were pretty basic, leetcode easy, CN questions were also pretty standard and same for OS, they asked me a lot of questions back to back so that was one thing, went smooth ans every question correctly. 2nd round was managerial round, and there I was rejected (recieved rejection just 5 mins after the interview). Interview was pretty serious with my ans and was processing each and every words. If he feels that this or that should be included in my answer he directly said me that after each question as a feedback.
