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.
