Also, I sort of shortened the story above, but the other intangible thing I saw others maybe would not have picked up on is when I gave all the candidates a tour around our set up, we had these Symbolics computers to do some back end AI stuff (early days stuff) and we needed a Symbolics slayer. I just saw the look in his face when he saw those things, you could tell he was truly excited about working on them. They all said they wanted to work on them of course but just how he looked at them.... I just felt like that was going to make a difference.
In today's world it would not fly if I told HR that I was choosing this guy because he looked at the computer equipment they way a dude looks at a sexy lady.
