When applying to a certain job, you want to show a future employer what you did beforehand and to prove to them you are worthy of the position. That is why you put examples of previous experiences that could be relevant.
<u>If Tony is applying to work as a fashion photographer, </u><u>he should list where he worked previously and put examples of his work in the experience section. </u><u>This way the future employer can deduct from the work what Tony can do, what has he learned so far, and if his experience is good enough for the magazine.</u>
