A resume that is two pages long provides plenty of opportunity to identify your accomplishments, yet is not too lengthy for a busy employer to screen. Make no mistakes. Errors send a strong message that you may not be accurate in your work or disciplined enough to correct errors. If possible, let it sit for a day then recheck it. Make it neat, clean and legible.
Career objectives are often either too limiting or too broad.
A cover letter is often the better place to state your objectives. Chronological is the way to go. Start with the most recent employer first and work chronologically backwards. List specific accomplishments. Use action words and don't be modest.
