On a job interview, presenting yourself in a professional and put-together manner may be the key to your success. Traditional advice is to always dress the part for an interview, and that includes hair, makeup, jewelry and personal grooming. Your potential employer will make a judgment about you based on the first few minutes of meeting you. Right or wrong, her initial impression of your skills and abilities may be based on your look alone. That’s a lot of pressure to put on a hairstyle, but if you follow these tips when prepping for a job interview, you're more likely to make a good impression.
