Someone can be a poor people-person and have little education but delivers in a job that doesn't heavily rely on these other factors. They might get stuck in fairly narrow roles though.

I think being a good networker is tied with being good at communications and interpersonal skills (they’re both ranked closely). Someone can be good at these but went to the school of hard knocks and doesn't deliver at work. They’ll go some way but they might have to move around jobs/companies a lot.

Someone can have be great at passing exams but is a loner, can't communicate and doesn't deliver in the workplace. It’ll be difficult for them to get past the job interview stage. At any rate, Knowledge isn’t just acquired through books and exams. And Wisdom can be gained through one’s own experiences and one’s networks.

But it's hard to be lucky for very long when you're anti-social, uneducated and don't deliver at work.

Overall, it seems to depend on the jobs and organisations. High-level vs low-level, technical vs relationship job, big company vs small company, political vs meritocratic company etc.
