Yeah, I feel as though some people just don't understand how much of your time can be wasted during the hiring process. It's really not unreasonable to pass over a résumé for including/excluding certain content, though I don't think the inclusion of an Objective section should be grounds for not considering someone for a position. I'll take that over someone sending me a screenshot of their résumé from their phone (usually with the phone UI visible and with the résumé partially cut off), sending me a résumé that's clearly intended for a different business or sending a résumé with a lot of typos on it. It's always irritating when someone sends a résumé as a Pages file, but I'll at least have the decency to email the person applying and ask him/her to re-send it in DOC, DOCX or PDF format, because it's just Apple's arrogance that allows people to so easily send a document in a format that Windows users won't be able to view without jumping through a bunch of hoops.
By the way, I've heard of people not considering applications submitted by mail some of the time because the stamp is crooked on the envelope, so it's not as though the means of weeding out candidates has always been the most sensible.
