good technical qs on dsa, cs fundamentals with resume based questions asked with 2 technical and a mangerial/hr round all topics covered(sql,os,cn) each round goes up to 30 minutes and elimination rounds

I recently had an interview with BT Group, and it was a positive experience overall. The first technical round included 3 DSA questions, where the interviewer was supportive and provided helpful guidance. They also asked a few basic OOP concepts questions, along with 2 puzzle questions and 1 pattern-related question. The second technical round focused on machine learning and deep learning concepts, with 1 simple DSA question to wrap it up.Finally, the HR round was straightforward, with simple questions about my background and fit for the role. Overall, the interview process was professional, and I appreciated the supportive environment created by the interviewers.

They had one online test followed by the interview on campus which included group discussion, technical and HR round. The group discussion will have very general topic where you have to choose for or against the topic.
