If you're on a serious job-hunt, you might be jaded by all the rules and regulations the "employment police" say you should abid
Breakable Rule #1: No phone calls mean never call. The average hiring department has more than one fax machine and more than one printer. The odds of your resume reaching the right person are far less than perfect. If there's a job that's perfect for you and you haven't gotten a call about it, try calling after hours and leaving a 10-20 second voice mail message describing your excitement and your match. If you seem right, you'll get a call.
Breakable rule #2: Resumes must be one page. No good recruiter has ever stopped reading an interesting resume at the end of the first page. Truthfully, they're more likely to skip around for the information they want. And if that's on page 2, they'll find it. Keep your resume to one page until you've got 10 years of experience under your belt, then use whatever paper you need to sell yourself.
And Breakable rule #3 when it comes to job-hunting: Cover letters are about you. Imagine a stack of cover letters and resumes with each one claiming that the writer has "the skills and experience for the job opening." The cover letters that stand out discuss the needs of the company, the particular challenges it faces, and how the candidate's skills and experiences can help. An introduction like this'll get you much further in the hiring process than a generic, "insert job here" cover letter.
