There are a number of entry-level jobs that don't require much social interaction, but you'll have a small chance of getting promoted. No matter what you're doing, advancement often means managing others, helping others with their jobs, organizing teams, talking to clients, etc. The good news is, it's not too late. Some people seem to be born with awesome social skills, others have to learn them; but they are learn-able. I would consider social skills as important as any other technical skill you're learning in school; they will be just as important in the long run.
