Misstating anything, either orally or in writing, will only wind up being counterproductive, because as soon as the employer detects a lie, you will be removed from consideration. If you feel something in your professional or educational background may stand in the way of your job search, stress the positives about yourself instead of lying. There are many ways to project the image of a likable, confident, happy and capable person, the kind of candidate an employer is looking for. In an interview, instead of speaking generalities about how wonderful and capable you are, give concrete examples of how you contributed to a company's performance. You do not need to lie or exaggerate.
Good work speaks for itself when properly presented.
Avoid mentioning anything that may be perceived as negative. Give examples of your ability to work well with others. Employers, today more than ever, want to hire people who will fit in well with the company immediately and be effective team players. By citing positive examples, you will give the employer reasons to screen you in, not out.
