BEagle,
This isn't a new thing though. I have scores of CVs coming across my desk in a typical week, from applicants still completing PhD's to Professors nearing retirement age. The presentation standards don't seem to correlate to year of birth or expertise, rather, they just seem to correlate to a personality type.
It can be frustrating as their presentation of work often emulates the sloppy CV standard, but the actual quality of work again seems unrelated to the presentation.
I agree that a certain degree of decorum in public is required, especially when representing an employer. At the same time though, the judgement that one persons smarter haircut constitutes a better work ethic, a tie indicates professionalism, or a suit ahead of smart-casual shows greater committment are in my opinion counter productive and quite possibly over-opinionated judgement calls.
