If these ridiculous interviews don't produce top notch performance reviews after a year on the job, then the interviews are worthless. If I were to ever try a startup (I won't), my philosophy would be to hire easily and fire easily. Do my level best to interview fairly, and give people a chance. But if they don't work out, fire them quickly and give them a 2-3 month severance bonus. Then I would remove most titles and pay in the top tier. I think at the beginning of hiring, it would probably have a high turnover, but as the company matures, if it survives it will be filled with a lot of happy engineers that won't want to leave.
