It’s astounding that the very people whose job it is to be concise fail to be concise on their most important document: their resume. I plead guilty to this word-crime.
After consulting with an expert, I reduced my resume from 650 words to 300. How? By hacking off the crap that had accumulated over the years, and then simplifying the leftovers.
My resume is now a page and a half and can be read in 20 seconds. Considering the mountains of lengthy resumes employers must sift through, a short and concise one is a breath of fresh air.
Isn’t this extreme editing? Yes, it is. Try it; you can always back up your super-sized resume.

I couldn't agree more. You should really look at your resume as a marketing document: your “highlights” or “key features”.
Think about what parts of your career the client would be most interested in and make sure you emphasize those. Then trim everything that's nog relevant for the job you're applying for.
You could however leave one or two extraordinary hobbies or former jobs to serve as an icebreaker.
A shorter resume gives you more to talk about at interview! I fit all the basic stuff (software competence, work history, education, personal interests) on one page and dedicate the second page to a list of mini case studies of projects I've worked on.
It works for me – the last time I was jobseeking I got three interviews in three days, which resulted in three job offers. I then had the glorious problem of choosing which job I wanted the most 🙂
