From what I have seen, job seekers tend to make several mistakes on their resumes. Some of these mistakes cost people potential jobs.   Please avoid these mistakes at all costs.

1. Troublesome Typos and Grammatical Errors – Hiring managers view your resume as your introduction and your attention to details.  It only takes one or two typographical errors to remove you from consideration from a job.
2. Overly Casual Conversation – If you are not professional in your communication, hiring managers will view you as unprofessional and not worthy of their company
3. Lies – Do not overstate your responsibilities or background. If a hiring manager verifies your resume and finds a lie or overstatement, you will not be hired for that position.
4. Personal Information – Employers research their candidates including checking your Facebook page and your personal blog.  What you say or post on a social networking site or a blog can come back to haunt you.
5. References – If you list a person as a reference, you need to know what the person will say about you.  The last thing you need is a bad reference.
6. Juvenile E-mail Address – if you have had a cute or suggestive email, you need to get a new one from Yahoo or Google.  Sexy69@aol.com will been seen as a negative for any hiring manager and another question mark on your professionalism.
7. Lack of Specifics – A vague description does not help promote your skill sets and will not differentiate you from any candidate.
8. One Size Fits All – If you build your resume for all employers, you end with a vague resume that will be briefly and discarded right away.  You need a resume targeted for the company and the job.
9. Highlighting Duties Instead of Accomplishments – A hiring manager is less interested in your duties as opposed to what your accomplishments.
10. Too Long or Too Brief Resumes – You need to provided a hiring manager with a good understanding of what you accomplished and what you are looking for.  If you make your resume too short, then you lose the substance of your resume.  If you make it too long then you no one will read it.
