Ask HN: What do you look for in your first 10 hires?

I've been helping a few companies recruit founding engineers. After doing a lot of screens I have a rough idea for what to look for. For others that have done a lot of hiring what do you look for specifically besides their technical ability?

I think this is where you’ll define the company culture. Maybe in the first 10, but certainly in the first 100. If you want to design the corporate culture, this is where it starts.
