As we said, an interview is a potentially nerve-shredding, stress-inducing experience. By letting even some of the negative emotions surrounding an interview get to them, potential applicants forget to do some of the most basic bits of body language to encourage an interviewer. An interview is, at its very core, an opportunity for you to showcase yourself as a candidate and be rewarded with a job. By carrying yourself with even something as simple as a good smile, you convey a whole level of confidence and enthusiasm that charms even the toughest of interviewers into realising your potential. It also helps establish a connection between the two of you during the interview that makes the chances of them remembering you rise drastically.
