Ok, that is not a beard. A beard is full coverage of the jaw line extending over the mouth area. What you have makes you not look your age, but look like you are trying to be older than you really are... or trying to grasp back to the old grunge look... unsuccessfully. Don't worry, I can talk, I have the same problem... for that matter I can't even grow a mustache... and I am 32. If I were you I would first shave, then go and get a clean haircut... nothing works better for me than a high & tight military cut. Both factors here give the appearance of organization and maturity. That is a lot of what an employer is looking for.
