Hire specialists with extreme strengths in one area, even if they're weak elsewhere. A team of people who excel at different things covers more ground than a team of well-rounded people who are just okay at everything.
I've learned that in any team, you can look for two types of people. You can look for people who lack weaknesses, meaning they're pretty well-rounded, they have no fatal flaws, but they may not be great at anything. Or you can have some people that are amazing at some things and kind of weak in other areas. I've learned that the best performing teams are filled with people who are amazing in at least one area. So you're hiring for an extreme strength, not a lack of weakness.
