The first impression you make on a potential employer is the most important one. The first judgment an interviewer makes is going to be based on how you look and what you are wearing. That's why it's always important to dress professionally for a job interview, even if the work environment is casual.
Don’t give the interviewer a chance to rule you out because you dressed inappropriately.
You'll want that first impression to be not just a good one, but, a great one. The candidate dressed in a suit and tie is going to make a much better impression than the candidate dressed in scruffy jeans and a t-shirt.
DRESS PROFESSIONAL – If you’re not sure of what to wear to your interview, call the company and ask someone in their human resources office. They’ll be glad to tell you.
DRESS – The best advice is to dress on the conservative side, clean and pressed. Loud designs of shocking colors should be avoided. Solid plain basic colors are advisable. (Navy blue, black, or dark grey)
TIGHT PANTS, JEANS AND LEVIS, SHORT SKIRTS OR SEE THROUGH BLOUSES, BLOUSES SHOWING CLEAVAGE, SPAGHETTI STRAPS ARE INPAPPROPRIATE.
HAIR – Should be attractively styled and cleaned, above all, neat and cleaned. Get the interviewer to notice your face, your expressions, your eyes – not your hair style. Caps, hats, scarves or headbands are not appropriate for an interview.
FINGER NAILS – Must be clean, trimmed or shaped. Again, excessiveness will hurt you. If polished, use moderation in color. Clean nails without polish of any kind are still the best.
TOE NAILS – Same as for finger nails.
CHEWING GUM – is a definite NO NO!!
SMOKING – do not do so on the day of the interview
