Very good analogy. And true. My dad used to own a used car dealership back in the day. He bought pretty much anything he could get for a good price that was in decent shape. If he only bought cars that were in perfect shape, he'd have pretty much no cars on his lot.
And I've worked for companies whose bosses are so damn picky about who they hire that they would go without hiring a single person even after conducting hundreds of interviews themselves over six months, as the rest of us were struggling to keep up with the workload.
It got so bad one time the higher ups eventually had a recruiter just pick a few people and said "Here, these are your new employees. Get them up to speed." and he just had to accept it.
