The opposite of TMI is TLI -- too little information.
Being too general in the resume is just as bad as being too wordy. Usually too little information takes the form of no details on achievements. Most people can get their job duties or role descriptions down, but falter when it's time to detail their successes in some sort of quantitative or qualitative way. As a result, the content is thin or bland and doesn't inspire the reader to make contact with the job seeker.
