The issue with defaulting to yes is that then you're going to be a hiring a lot of mediocre people who say just enough to appear "okay".
"A" players want to hire people better then themselves who elevate both themselves and the team.
Not getting into how most "B" players see themselves as "A" players (dunning-kruger?), unconscious biases, or people who are just bad at playing interviewer (esp. people who have done it a certain way for their entire careers and are unwilling to even think that a different process might yield betterresults).
