When preparing your resume to send out for potential employment, first take time to study the chemical engineer job description. Usually these descriptions are filled with keywords that your potential employer will scan your resume for. Often your resume won't be seen by an actual person until after it passes through one of these scans. It's important that you don't get disqualified early in the game for a technicality. Adjust the language in your resume to match up with the language in the job description.
Don't let your research end at the job description, however. Getting through the scan is only step one. Once you have your interview you must wow an actual person, which isn't as easy.
