We simply have a specific bar for admissions and everyone above that bar gets admitted
In my experience on hiring committees, this is actually quite difficult to do. I think in practice it is much more common to operate with two clear bars: one above which everyone gets hired and one below which nobody gets hired. The ones in the middle get a bunch of situational criteria applied to them and it’s pretty impossible to keep “we’re feeling tight on space” out of the equation there.
