When I was at Google, interviewing was considered everybody's job, but without any particular benefit from doing them. They'd just try to guilt you into doing them. (I think they'd try to guilt some people harder than others, though.)

I think this is a mistake. Interviewing is a teaching/sales role and many people need coaching to come across as friendly. They aren't going to get that coaching if they see it primarily as an obligation.

I did them for many years out of a feeling of obligation, but if I got better at it, it was slowly, and with diminishing returns. It was just more of the same experience.
