Hi Ava: I think you're on the right track in terms of wanting to portray what the company needs, but don't put on too much of an act - you don't want to seem fake! Ultimately, it sounds like the real issue you're having is feeling confident during your interview. Trust in the fact that you deserve that interview. Sell yourself, but don't go overboard. Just be yourself - eventually, you'll find an employer who wants to work with you!
