It's deceptively easy to make mistakes on your resume and exceptionally difficult to repair the damage once an employer gets it. So prevention is critical, whether you're writing your first resume or revising it for a mid-career job search. Check out this resume guide to the most common pitfalls and how you can avoid them.

1. Typos and Grammatical Errors

Your resume needs to be grammatically perfect. If it isn't, employers will read between the lines and draw not-so-flattering conclusions about you, like: "This person can't write," or "This person obviously doesn't care."

2. Lack of Specifics

Employers need to understand what you've done and accomplished. For example:

A. Worked with employees in a restaurant setting. 
B. Recruited, hired, trained and supervised more than 20 employees in a restaurant with $2 million in annual sales.

Both of these phrases could describe the same person, but the details and specifics in example B will more likely grab an employer's attention.

3. Attempting One Size Fits All

Whenever you try to develop a one-size-fits-all resume to send to all employers, you almost always end up with something employers will toss in the recycle bin. Employers want you to write a resume specifically for them. They expect you to clearly show how and why you fit the position in a specific organization.

4. Highlighting Duties Instead of Accomplishments

It's easy to slip into a mode where you simply start listing job duties on your resume. For example:

• Attended group meetings and recorded minutes.
   
• Worked with children in a day-care setting. 
   
• Updated departmental files.

Employers, however, don't care so much about what you've done as what you've accomplished in your various activities. They're looking for statements more like these:

• Used laptop computer to record weekly meeting minutes and compiled them in a Microsoft Word-based file for future organizational reference. 
   
• Developed three daily activities for preschool-age children and prepared them for a 10-minute holiday program performance.
   
• Reorganized 10 years worth of unwieldy files, making them easily accessible to department members.
