A resume longer than two pages never get much attention.
Be Brief.
A resume is like a preview, a trailer to entice the recruiter to call
you for an interview, not the entire movie. So be brief.
Cut ruthlessly and eliminate all projects, tasks, and information that
isn't relevent to the job requirement you are applying. If in doubt
about something delete it. When you doubt the relevance of that
information in your cv then how will the person at the other end will
believe it?
CV is not a fish hook that you are just throwing into the pond to
catch any company. It's should be a net that invites interview
requests from the companies you want. So design it properly.
