If you Google Information Technology Resume, you should find a number of examples and some advice. As an IT manager with a large state government agency, I was always looking for Jacks and Jills of all trades. An Expertise or Skills portion of the resume is the place to highlight what you have to offer, preferably edited to your understanding of the position you are seeking. Don’t omit mention of other IT skills, but don’t devote much space to them either. Make the connection in the Experience and Education/Training/Certification portions of the resume showing how the skills were acquired, applied, and/or documented. Exposure to many aspects of IT by moving from job to job without mastering anything is not desirable. Successfully doing many different things in a small IT shop out of necessity shows potential but could indicate lack of exposure to the kinds of challenges inherent in the position you are seeking. In addition to the technical aspects, this includes working with a more complex IT and client organizational structure and the standards, policies, procedures, etc. that come with it. Dispel concerns about job hopping and the limits of a small shop background in you resume if possible.
