A strong cover letter and a killer resume can secure you a job interview. Once that face-to-face happens, though, those two things won’t carry as much weight as what you do and what you say during the interaction. Your presentation and your body language will be the tools that can give you the edge, especially when vying for a competitive position.
First thing to remember: If you got the interview, the employer thinks you’re qualified. So don’t be bashful, don’t be scared and don’t be afraid to act confident. In fact, they expect you to be confident and conduct yourself like you know what you’re doing — that’s why they’re giving you a sit-down in the first place.
