Two reasons: The idealistic reason is that I didn't want to participate in a corrupt system. AFAICT, an individual interviewer is powerless to change the system. I've I'd have rated every candidate a must-hire, they would have thrown my feedback out. The more practical reason is that I was a SWE embedded in a hardware group. Interviewing (and writing up the feedback) takes time. My spending time on interviewing would not have helped my boss (or his boss), so when I told my boss I didn't want to do interview training, he didn't care. This kind of paid off, because I got to spend enough time doing stuff my boss (and his peers/bosses) cared about that I got promoted while I was there.
