Length of Resume

A resume is a window designed by the job seeker to give a glimpse of himself to the world of jobs.
Make sure your resume gives only a glimpse not the whole of you away. So to the point and crisp points always leave a deeper impact.
Just when you least expect you get a call from your dream company you contacted long back. And then? You are being asked to drop your updated resume.
Here is where the battle starts. What should your resume look like? How big is big enough and how small is too small?
Well, under much debate though, this is an extremely subjective choice.
