I think "team fit" as you've described is probably the most important factor for me. But it's a really tough thing to interview for / create within a team.

I had a coworker who could be described as a 'social butterfly', someone who can talk to anyone for hours on end and make them feel comfortable. They would spend half an hour with each interview candidate, not asking any technical questions, but just having a friendly conversation. Then they would give a 'yes/no' opinion of whether we should hire the candidate. All of their preferred hires were very successful and fit in with the team. It was remarkable. Some people are just excellent at reading others. Most people really aren't sadly.
