> I am confused why people are so outraged at the idea that some part of selecting people to work with may be based on whether you get along with them.

Because in large companies you will not work with the people that hired you.

Many successful sport teams were composed by people who openly disliked each other, there's no reason to be likeable if you are not being paid to be liked by others, but there are many reasons to cooperate to the end goal if the team members' salaries depend on it.

For many people being likable in the way it is represented in the article it's more stressful and energy draining than the job itself.

I would go as far as to say that people that can't go through first impressions and work together with someone they don't particularly like (except of course if it's for good reasons) aren't good team members.

But they tend to select each other to not feel alone in being bad team members.
