With this question, the employer is basically asking you why they should hire you over any other candidate and they’re also testing how well you know yourself as a professional graphic designer. Again, with this question it’s important to be honest and to think about what qualities and experience you might possess as a graphic designer that other candidates might not – this could be your previous client base, the range and depth of your experience – or even some of the techniques you’ve picked up in your career. Whatever reasons you give, be sure to have some examples to hand so you can back them up.
