Such a feedback loop -- of identifying which interviewers give the "most accurate" scores -- doesn't exist. Nor is it clear how you would build such a system (how do you quantify a "bad hire" or "good hire" in such a way that isn't lost in the noise?). Interviewers are trusted to do the best job they can.

Remember, interviewing is volunteer work, not something that will advance your career. The results of the interviews and committee deliberation are confidential, so there's no way to gain a reputation for being a "great interviewer".

Ah, but you are woefully naive if you think some interviewers don't slip in who enjoy having people struggle with problems so they can stroke their own ego. There are also the ones that have seen the quality of engineers significantly decline over the last 6 years of massive expansion and just want to gatekeep.

One of the major flaws in Google's process is assuming that the engineers are incentivized to find good hires.

I hope that at least engineers are given courses in "how to be a good interviewer".

It's not a natural skill, dare I say it, especially for an engineer.

Sounds like a good interview question.
