General Cognitive Ability (GCA): How you break down problems and learn new things. Not about what you know, but how you think.
Role-Related Knowledge: Technical skills and experience for the specific job.
Leadership: Google calls this "emergent leadership." Can you step up when your skills are needed, then step back when others should lead?
Googleyness: Comfort with ambiguity, bias toward action, collaborative nature. Not about being quirky. About working well with others.
