Charley I don't think application forms are personalised as such so are not really a reflection of the company's ethos or attitude to staff.
Many forms are a total pain, with unnecessary questions, and mission statements, etc., but you're just going to have to 'suck it up' Phoenix.
They will realise your age range immediately.
I'm reminded of an incident that became public recently, can't remember the organisation, where an email detailing what should go into a job advert, said something like
"We welcome applications from all sections of the community, blah, blah and all that crap"
But if you don't apply you won't be in with any chance!
Just a reminder Phoenix last year my 55-year old sister was recruited for a good well-paid admin job in a big organisation. It's a high profile place so would have attracted many applicants, no doubt many much younger.
