I've been using the standard boiler plate resume and cover letter and customizing it to fit the position that I was applying for. Well, evidently that hasn't been good enough. So I decided to let a professional have a shot at it. She whipped up my resume in under 30 min. and was quite pleased with her work. I, on the other hand, wasn't as excited about her work as she was but she was the professional so I didn't question her. The format looked wierd and she had left out what was to me very important information.
I uploaded my resume and within two days had four requests and landed an interview with a South American company starting up new operations in the US.
So, if you think your resume is all that and a bag of chips, you may want to have a professional take a look at it. After all, getting your foot in the door is what it's all about.
