This thread has provided a lot of useful tips, but I think the thing that's niggling me about it is that a lot of the 'errors' which are being complained about as being bad CV etiquette which may result in applicants not getting called for interview, are committed almost exclusively by older candidates.
Including your DOB, writing at length about extra-curricular achievements, turning up in person to hand in your CV (because it shows keenness), going line by line through the person specification and referring to every item there (what? seriously? I've never done this - I just pick the 'highlights': 'Must be proficient in Excel' - fine, I'll talk about how I can use Excel; but for something less quantifiable, not so much. I'd be less likely to spell out explicitly 'I can do X' because I would assume the recruiter had a brain and could work out that if I'd had, say, multiple public-facing roles then I felt confident handling enquiries).
This is the way we were taught to apply for jobs (along with 'Chance your arm - it doesn't really matter if you don't have ALL the relevant experience, just fudge it a bit and play up your strengths!' For real.) So by instantly discarding applicants who do these things, it's indirect age discrimination.
And no, I don't believe it's enough to say 'Well, that's on them because they should have gone out and got some advice about modern job-hunting techniques' because why would they think of that? If someone hasn't applied for a job for ten, twenty, thirty years (either because they've been a SAHP or just been in the same post all that time), why would they necessarily assume that the rules around how to write a CV had changed? It wouldn't be my go-to thought. TBH it had barely occurred to me, beyond a vague notion that some (SOME) employers didn't like you to include DOB these days. It's not like these changes are made public anywhere, so unless you know someone personally who's in recruitment or has been through the same thing themselves recently, you're just unaware.
Add in all the poor souls who are getting told wildly wrong things by job centre coaches and you have a lot of applicants who are committing all these CV blunders in innocence. I really feel for that older teacher you mentioned. The poor woman. I’m sure she thought her experience spoke for itself (another phrase we heard a lot 'back in the day').
What's the answer? Idk. Maybe companies should offer mandatory CV training to all employees who've been with them for more than five years, but then they'd be paranoid that those people were about to leave and would probably try to edge them out for disloyalty or some shit. Honestly I hate the business world so much, and more than ever after this thread.
