Depends on the company
I got my last job with 1 page (company is a 15-20 head in the agency / digital marketing area). I listed :
* Last 2 jobs, listing company, dates of employment & Job Title.
* List of Education / Certification (only relevant to the job)
* List of notable skills (written in a very broad manner, i.e : Administration of Windows, Linux and Mac OS X servers and major application packages.
Add a references on request line and contact details and I was done.
May not suit everyone but worked well going into a small and casual environment.
