The list of companies/roles/descriptions/dates, and the list of universities/degrees/GPAs/dates, is the least interesting part of your résumé and should take up very little space. Most of it should be what projects you've done (for an employer or otherwise), presentations/publications, or other unique things. I've been in the position of reviewing résumés for hiring, many times, and the list of companies gets a brief perfunctory glance when filtering, and then a second glance before the interview when looking for prompts to get the candidate talking. Projects are going to get a much closer look, to get an idea of what they did, what skills they demonstrated, and what we should spend more of the interview talking about.
