Cover Letter Q & A

Q. How long should my cover letter be?
A. Generally, cover letters should be one page in length. This is true for approximately 90 percent of all cover letters.

There may be instances, however, when one page is not enough. If you believe that the information you are including in your letter is essential information that is not communicated in your résumé, go ahead and prepare a two-page letter. But be sure that everything you’ve included is vital to favorably presenting yourself to a company or recruiter.

Two-page letters are most frequently used by the following types of job seekers: career changers, industry changers, senior executives, scientists andtechnologists, people seeking government jobs and people seeking university and academic appointments.

Missing qualifications
If you’re applying for a particular job, yet the required work experience is nowhere to be found on your resume, it is destined to end up in the useless items pile. Be sure you include skills and distinct work experience that match the job description posted.
Hint of uncertainty
Avoid vague job objective statements. Clearly state the kind of job you want and play on your strengths with a firm display of confidence. Your resume should be designed to subtly “toot your own horn”. After all, you want to get noticed and land an interview, right?
Wordy is not always worthy
This is one of those times when less is definitely more. Your purpose is to grab the hiring manager’s attention not to tell stories about your childhood sweetheart, so refrain from using old fashioned, flowery words. Pitch the tone so that it gives the impression of a modern professional who is in touch with up-to-date business lingo and usage. Stick to factual words rather than descriptive adjectives; keep it brief and straightforward.
Higgledy-piggledy presentation
Don’t make the hiring manager dizzy. If he is not able to follow your resume and find what he wants, he is just going to give up and put your resume on the no-way pile. Unless specifically required, too much detailed information is redundant. The most interesting part of your resume from the hiring manager’s vantage point is your work experience. Place it at the start; and not your personal or educational background.
Unreachable jobseeker
It may sound almost like “no-brainer” but giving inaccurate contact information is a mistake some jobseekers frequently make. If your phone number has changed or your e-mail is not professional-looking, employers won’t make any effort to contact you. Be sure you update your resume accordingly.

Cover letters are the best way to introduce your resume to potential employers. Here are a few sites that have example cover letters to help you get started.
