Self-Promotion
Your résumé is an advertisement for yourself, and should therefore be presented in a convincing manner that will most effectively "sell" your past experiences. Each bullet in your experience section should start with an action verb (using past tense for previous jobs and present tense for current jobs) to make it powerful and descriptive. Avoid the very bland phrase "responsibilities included." Wherever possible, use concrete numbers and examples to highlight accomplishments (such as the amount of money you managed as a treasurer or the ratings you received as a teaching assistant). When describing an experience, highlight what you did and how your approach may have been unique and effective. Try not to just reiterate the job description, especially if it is a well-known job.
It is important to emphasize the importance of honesty. Although you do want to "sell" yourself, never misrepresent or exaggerate any information on your résumé.
