The demands for background checks tends to be inversely proportional to the ability of the employee/applicant to do criminal or civil harm. You'll need a clean criminal record to work a random retail job but could have numerous convictions and be a software developer. A crummy rental will require it but fancy executive rental will not.
I know some of this has historical/data underpinnings on experience, but fear most of it is based on biased expectations.
In my experience you will more likely see it if you are in a shop that is paying below market. I.e. Devs there make 10k less than other local shops.
We wound up with some interesting folks. Got to see what someone going through methadone withdrawals looks like. On the other hand, a few people got some really meaningful second chances at a career there.
