Presumably when you say GOOD you mean good for the position. If you take a holistic view, that metric should encompass things like how they will work on the team, whether they will fit in, and even whether they will be good for the company.

If your company gets measured (as it will) by future prospective job candidates beyond just this one hire, one thing they will look at is the health of the company (see the article).

A lack of diversity in a company does not say anything conclusive, but it can be a red flag.

As a very low level hiring manager (which it sounds like you may be, very low level) you don't have to think about this much. As you ascend to higher levels, the environment you are providing for employees, and consideration of how each employee you choose contributes to that environment, becomes more of a consideration as to whether someone is not only GOOD at what they do, but also GOOD for the company.

And if someone with an overwhelming advantage in the job marketplace gets edged out in a tie-breaker amongst equal candidates, cry me a river; they will be just fine.
