Has there ever been a company that doesn't say they hire "only the best"?
Yes. The police in the US explicitly reject people with high IQs. It has been challenged in court but upheld. https://www.kake.com/story/32508747/court-oks-barring-high-i...
I don't agree with this personally, but what they are doing is not equivalent to them exclaiming that "We don't hire the best". It would only be equivalent if they were explicitly filtering-out qualities they believe contribute to being the best, such as discipline, strength, and the like.
