Your body language says a lot to recruiters.
Having a firm handshake, smiling, making eye contact, and reducing fidgeting portray confidence and interest. Avoid crossing your arms or putting your hands on your hips. If you don’t know what to do with your arms, carry a notebook or portfolio with your resume. Doing this will not only give you something to do with your hands and arms but also make you appear more prepared; more importantly, it allows you to take notes.
