Are one-page résumés passé?  How long is your résumé?
timr: How long should it be?  The premise of the question is flawed -- nobody is going to shoot you if you don't submit a one-page resume. There's no law against it.But if a resume is little more than a marketing tool, then brevity is your friend.  One page is better than four, even if your career can fill ten.(One notable exception:  if you're in academics, long CVs are considered better than short.  Academia is not the real world.)
