Not very good experience there, my interviewer came late, then in shortage of time started asking question with any discussion. And just to wrap up the interview quickly asked 3 question and told me i am not fir for the job

It was easy, Interviewer just asked me basic question on CS fundamentals, no DSA questions were asked. Interviewer was friendly and understanding, only one interview was held. Just be confident in what you answer.

The interview consisted on 3 rounds. All included technical questions from resume. Just study your resume well and be ready for behavioural questions. They would also ask some basic implementation on what your work was done and how did you implement that
