> I would assume "liking each other" is usually a given job requirement. Not really. I've had plenty of co-workers over the years I did not particularly like, but with whom I've had very productive working relationships. I'm not saying I actively disliked them, but they are not the type of people I would have become friends with in other situations. There was the guy who was super into his micro-brewery, had to make…
But did you make the hiring decision for those people?
One guy was very awkward socially, over confident in himself and under-appreciative of everyone else. At least that is how he appeared in the interview. My team at the time rotated three people through as a hiring board to spread out the work of finding people and I was on the board that interviewed him. He was a very weird guy, and I mean more than your typical loner/introvert with underdeveloped social skills. We were a little worried about his ability to work well with the team, but on technical merits he was fantastic. He also didn't show any red flags, just general weirdness. So we hired him, and he was a good fit. Definitely in the top half of our team as far as quality and timeliness of his output.
I'm also glad that the people managing the hiring process for the other two employees I mentioned was willing to look at their professional record and not at their "culture fit" because pug-lady and microbrewery-guy were some of our best people. When I left the company where I worked with microbrewery guy, he was the one to whom I handed all of my outstanding projects.
