The interviewer was too much judgemental. Asked personal and irreelevant questions not required for job. On the technical side, the interviewer expected to finish writing DP code by the time he finishes the question. No follow-ups are allowed and no discussion. The interviewer will close the video and mute himself after utterring the question. I felt you can only answer if you have mugged whole DSA. I don't like this way of interviewing at all. I declined before they get back with the result of the first interview.
