When it comes to job interviews, what you look like counts. As shallow as it sounds, your appearance is one aspect of your overall person that may make or break an interviewer’s decision to hire you.
Before you say a single word to the interviewer, you have already made an impression based on how you are dressed.
Whilst dress codes in the work place have become much more informal with ‘dress down Friday’ seeming to have invaded Monday through to Thursday, job interview attire remains strictly professional.
The general rule of thumb is to dress in a manner that is professionally appropriate to the position for which you are applying. In most cases this will mean wearing a suit. Make sure you are comfortable in what you are wearing and that it fits well, so that you look and act your best.
Don't forget clean shoes, not too much perfume/aftershave, fresh breath (don't smoke just before an interview) and clean hair.
Dressing professionally shows respect for yourself, the interviewer and the company. You may not have to dress like this every day, but you are more likely to be taken seriously when you present yourself in a professional manner.
Physical appearance is a factor too - make sure you get a good rest the night before the interview so that you look and sound your best.
