How exactly does Mike “vet” people?

This comes up mainly in S5 when Mike says he needs to “vet” all the Vamonos Pest guys to make sure they’re solid enough to be complicit in the meth operation. He says the same thing about the employees of the cardboard factory when Saul pitches that place as a potential site for Walt and Jesse to cook.

A big example is when he tells Lydia not to kill the nine guys in prison. He says “They are solid, I vetted them with great care.” By “solid” he seems to mean that they won’t rat on anyone. But how exactly could he know that about someone with certainty?

I get that Mike is a licensed private investigator and clearly he has his mysterious ways, but how exactly can he vet these people? Can he really investigate them deeply enough to figure out whether they would rat (since it seems that’s mainly what he’s worried about)?

I don’t know anything about PI’s, so if anyone who does could fill me in on what exactly this “vetting” process is, that would be cool
