The interview was in 2 stages: First was the technical round- In that interviewer initially discussed the questions which were there in the written round. In total 3 questions were discussed, where I explained my approach, and then the interviewer asked about the optimized approach for the same questions. Later some questions related to complexity were also asked. The next round was a simple HR discussion round: I was asked if I have any plans to do further study now and basic questions like intro, strength, and weakness. Finally, I was selected!
