Other than my first resume, I've always used a chronological format that lists work experience first, followed by a very brief section on educational qualifications. If necessary, I'd include another brief section on relevant off-job skills, e.g. community contributions, etc.
In the work experience section, I list each major job position held, employer and duration, followed by 3 bullet-points of major contributions in each position. Prospective employers have (so far) responded positively to the bullet-points.
Once I have a "standard" resume done, I'd modify it slightly to suit each job application by highlighting specific related skills and experiences.
I've never been keen on wordy resumes (especially if the candidate does not have a good grasp of English grammar, and I was hiring mostly for teaching positions), so I've learnt to keep my own resumes concise and relevant (in this case, not more than 2 A4-sized pages long, printed on only 1 side).
And get a nice smiley warm and sincere-looking photo taken, preferably in a studio by a professional. Dress professionally for the photo as well.
Hope that helps.
