A resume is a menu, not a cookbook.  It’s purpose (and it’s ONLY purpose) is to encourage a prospective employer to invite you in for an interview.  Contrary to many claims, a resume will not get you a job offer or a higher salary.  You must do that during the interview and negotiating process.

If the resume is too brief or too general, it will not spark the interest of the reader.  Put in too much information and the reader may feel overwhelmed and may not be able to focus on any specific thing.  In either case your chances of being invited in for an interview are greatly reduced.

An effective resume strikes a balance between the two.  Like a menu, it should be attractive, uncluttered, easy to read, yet INTERESTING.  Like a menu, it should provide something that will be of interest to a wide variety of readers in your field, yet not provide all the details about how the individual dishes are prepared.  A resume is a menu, not a cookbook.
