I've been given this advice and I'm skeptical. You can only mask things to a certain degree, it can make you look like you're hiding something (which you are), and the hiring manager will figure it out soon enough in any case. If they really want to age discriminate you're probably better off finding out sooner than later anyway. In any case, later career jobs tend to come from personal networks anyway. My resume was just a formality for any interview I've had in the last 20 years.
It's not hiding anything. A resume is a two pages flyer to advertise your services. It doesn't pretend to accurately represent you as a person or 40 years of accumulated experience.
It's really bad if a resume never pass the first screening, it literally can't get a job. It's not reasonable to blame age for that, interviewers cannot guess the age from just a resume (and if they can they shouldn't let be).
Yes, it’s a flyer but it’s a flyer that many expect to include specific information in a specific format. You are free to ignore those expectations of course but employers are also free to draw various conclusions about apparent employment gaps, incomplete work history, etc. even if those conclusions aren’t warranted.
