Should the language of a resume be specific or general? Really, this isn’t a good question. The language of a resume should fit the kind of job you are applying for. It should show how you are qualified to fill the level of responsibility that the employer needs. Sometimes the terms will be broader. If you’re looking for a sales job that cuts across different industries, you will talk about sales in more general language. However, if you’re only seeking a sales job in IT, your language needs to reflect your background in that industry. That language needs to be more specific.
Beware of simply taking the job description for your current job and repeating it point by point. That language works for the job you are leaving, but it doesn’t show your next employer how you fit her needs. I recommend gathering 5-10 posts for the kind of job you’ll be seeking. Write your resume to appeal to the needs of these employers, speak to their key words, and match your technical skills to what you see in the job posts. A good review of the job posts will tell you how specific or general the language in your resume needs to be.
