Seconded
Where I work, the rule is simple. Everyone who is interested interviews, and if we all like, maybe we'll extend an offer. That's not guaranteed, though it is likely. If anyone doesn't like, we don't hire.
Getting rid of the wrong person after you hire them costs a lot more (money, stress, etc) than not hiring in the first place. And there are enough people out there that will work out that it is OK if you pass up a few who might have been great.
Similarly, if you have the wrong person on board, you want to fire them early (before they've done full damage) rather than late. But that's a position that you want to avoid being in.
Cheers,
Ben
