I've always felt like the best way to hire is to think in terms of teams instead of in terms of people. If you team is lacking communication skills, hire someone who have good communication skills, ignoring most other traits such as intelligence. If your team has great communication but is lacking in problem solving ability, then you should focus on hiring a really smart person, ignoring their communication skills. For this reason, I by default disagree with any article that decrees a certain trait that is "un-hirable"

The best team I was every on was a team that was basically hired randomly. The boss had tons of money (rich daddy was investor) and needed to hire 10+ devs pronto. Some people on the team were idiots, some were brilliant, some were communicative, some weren't, etc. No one was perfect individually, but we were all perfect as a whole.
