From the Google Research Blog:
- only hire candidates who are above the mean of your current employees.
- no hiring manager. Whenever you give project managers responsibility for hiring for their own projects they'll take the best candidate in the pool, even if that candidate is sub-standard for the company, because every manager wants some help for their project rather than no help. That's why we do all hiring at the company level, not the project level.
