If you don't get the position, seek out others like it (provided you really want that type of career). Keep trying. If you feel like your skill set might not be a good fit, it might be valuable to take a few classes in the areas in which you think you need some work. You can take a class a a local college or online... even brush up via webinar. The sky is the limit. Keep trying and, as the old saying goes, "if at first you don't succeed, try and try again!"
