I reversed my attitude for interviews. If the employer has an interview process that doesn't respect my time, my experience, and my ability, then I don't want to work there.

My attitude isn't "As a candidate, I failed that interview." My attitude is "That employer failed to have a process that enabled them to hire someone as awesome as me." I know that I'm a 10x-100x programmer at the places I've been, and if your interview process can't identify that, then that's your problem and not my problem.
