Expedia Group Software Developer I interview questions

4 round interviews, with 3 technical including design the OOD or class, data structure and algorithm, and one round behavioral question. I don't enjoy the BQ round interview, since they change the interviewer temporarily, the interviewer doesn't even know my name or my background, and didn't prepare for the interview. Very awkward BQ interview experience. I don't even think he has my resume before interviewing with me.
