The interviewer started off fine with him telling me the structure before proceeding, but then launched into a barrage of theoretical scenarios and technical questions. I was barely given enough time to talk about myself. The interview went half an hour over the allotted time slot with no acknowledgement from the interviewer. They were also eating off screen so I had pretended not to notice. I felt the interviewer did not wanted to be there. The recruiter couldn't be bothered to send a personal rejection afterwards letter opting for a generic one.
