On average, employers look at your resume for approximately fifteen seconds. Possibly not even that. If that find one misspelled word, one spacing error, into the trash bin it goes.
Not to scare you prospective job seekers, but resumes are an important part of applying for and getting jobs today. Your resume seems to put everything you have ever done in a page of words, but that's not quite the case. Instead, it should initiate conversation about an experience, an internship, something that you've done that you can talk about in an interview.
I had the opportunity to attend a session on "How to: Write a Winning Resume" through the Villanova Career Center. I learned a lot of things in that session, many of them technical, but more importantly I gleaned a few big points I'd like to share below, that may make or break the process.
1. Format the resume to the employer. If you have twenty-five different copies of a resume for job interviews, so be it. Each job is different and so should each resume be. One job may put a special focus on one area or type of experience over another. Respond accordingly.
2. Layout is everything. No one wants to read a block of text. Lay it out in a way that looks appealing to the eyes, with white space separating sections and headings for each appropriate area. This makes it easier for employers to find what they are looking for.
3. Don't feel afraid to hype it up. This is you we're talking about, right? Don't gloat, but if a reviewer asks you about an area be comfortable enough to expand on what you did. It's an interview, after all.
This post certainly isn't all-encompassing for writing a resume, but it should help to get you started.
In essence, take your time with this one page piece of paper. Make it so that it shows your abilities to the best possible level. Get that job!
