If you haven't been receiving callbacks from interviews, then perhaps you need to revamp the way you present yourself. Instead of emphasizing what you have done, try to steer the focus toward what you can possibly do.
There's a new study by the Journal of Personality and Social Psychology which found that recruiters favored potential over past achievements. The promise of what the person could achieve apparently stimulates more interest in people.
Draw up a list of things you hope to achieve at the job you're interviewing for, and try to make a case for why you are the right person to make those moves. To really impress the interviewer, tell her what you plan to accomplish in your first week to make your future achievements seem more realistic and tangible. Remember, don't give too much attention to your past achievements unless you can tie them into how they will help you in this new position.
