I think it's important to distinguish "introvert" from "lacks social skills". I'm introverted in the sense that social interaction drains my energy and solitude recharges it (with the stereotypical consequences like I don't like parties qua parties). However, I have good social skills in that I can make almost anyone like me, quickly. That is extremely useful in both getting hired and keeping a job.
