Most people fall into the trap of just listing job responsibilities.
Instead, provide a home number or a cell or pager number that you can answer discreetly. It makes recruiters wonder what you're trying to hide. Use the traditional chronological format, and address any problems, such as a gap in employment, in your cover letter. That neutralizes the issue from the beginning. Spin your resume to fit the new industry's requirements by selectively highlighting relevant skills and using the new industry's terminology wherever appropriate.
