What's next? The section that is almost always missing on entry level resumes: the Summary section. This section immediately follows the Objective section of the resume and is composed of "sound bites" of who you are. It provides the high-level support for the objective and draws the reader into the remainder of the resume, which provides further detailed support (Education, Experience, Activities, etc.). This section is crucial in the "high-speed resume review" world in which we live. Make sure it is there and bulleted with three or four one-liners about who you are and results achieved.
