When I teach or present workshops about networking, interviewing, and other aspects of the job search, I can almost always count on at least one person approaching me privately at the end saying, "But I'm shy and these things make me uncomfortable. Isn't there something else I could do to find a job?"
Whether you label it social anxiety, introversion, shyness, or whatever, the bottom line is usually the same: you're uncomfortable in certain social settings, particularly those involving a feeling of being on stage or performing in some way. For the purposes of this post, I'm not going to make a distinction between being "introverted" and "shy" since both traits face challenges in the job market. But if you'd like to read more about the distinction between introversion and shyness, this Atlantic article explains introversion quite well.
