This was very interesting. The recruiter called me and said whether I will be available today for an interview. I said that its on a very short notice, can we have it next week. The answer was that its better you have it today because today it would be only one round. Next week you have to go through three rounds. I was confused but agreed. Interviewer seemed not interested. Did not turned on the camera. Asked binary search and LLD of bookmyshow. I think he had prebuilt solution in his mind. Neverthless I wont comment as I agree that my design was not the best. The positive side was that I got feedback the very next day which is good
