the interview had nothing to do with the workload, and it seemed like they were unprepared for my interview. There were long breaks between interviewers almost as if they had no one lined up and were pulling people out of the office randomly to talk to me.

Very brief, asked some technical questions. Didn't really care about the person - just need to fill the role asap. It seemed like there was high turnover and the interview was to qualify you to get you in the office and start work.
