Exactly! Google famously did 8-10 interviews during their startup stage and they absolutely hired rock stars who helped them lay the foundation for Google's $2T company.
People who haven't build sustainable, profitable organizations typically have no clue about hiring. Sure, they may be able to hire well for their little project. But, if you care about the culture of the company and how you want to shape it, you almost want all of your current members to have a say in the new member
They hired rockstars because back then, all the rockstars wanted to work for them. The only focus of their hiring process was how to reject the 'B' candidates. They knew they would get enough 'A's applying that they couldn't avoid hiring a bunch.
For most companies, including Google as a more mature company, the dynamics are different. You might be quite happy to hire candidates who weren't top of their class but who are going to be easy to work with and get stuff done. And you want to make very sure you don't either reject or turn off the (maybe small number of) outstanding performers who want to work for you.
Google IMHO completely fail at the latter these days. A solid A student who knows how to present themself and really wants to work at Google will be hired. A genius with an unconventional educational background probably won't be.
