Having engaging and impressive content is at the heart of any resume, but style is more important than you may think. When an employer is paging through a stack of over a hundred resumes, he or she is going to pick up the one that looks best before reading a single word.
There's no one right way to style a resume, so it's important to take the time to look at many different examples for inspiration. Your school's career services office may have some samples for you to look at and an Internet search for 'sample resumes' will turn up lots of results.
