It's a good thing you've never had the position that includes interviewing someone for a job. Experience and qualifications are a very important part of the hiring process. I would never recommend a pottery maker for the position of machinist, I'd have been looking for a job myself if I did.
Whatever.
If you interview a candidate with impeccable experience and qualifications credentials...but discover there is the possibility he is a serial killer...I suspect you are NOT going to hire him without a great deal of investigation....if at all.
We have a guy here who MAY BE a sexual abuser. being considered for a job on the highest court in the land.
I think we should investigate thoroughly before even considering confirming.
