Yeah I sometimes get inquiries from people who say things like "do you have jobs where I can just walk Yorkies?"
And then of course the ones who do a great job of selling their qualities, and finish up with "I am available for work on Mondays, Tuesdays after 2pm, Thursday mornings and alternate Saturdays between 3pm and 7pm," expecting you to come up with a job that's tailor made for that schedule.
I'm guessing that technology changed things quite a bit. Back in my days, when you were looking for a job and you really wanted to work, you had to show up at this federal employment center where they'd post the majority available jobs, and that in itself was already like a job interview.
It looked quite bad to arrive later during the day unless you had another job. Priority was given to the folks who'd do the line before the office opened, at 8 or 9 am. Showing up after 10 am basically meant that you weren't a serious candidate. You didn't dress in rags to go there either.
If you were lucky enough to potentially find something, you'd first meet a counsellor, then (admitting that you succeeded getting through that first round), you'd get a short interview over the phone w/ the employer - mainly to schedule formal interview, but also so that the employer could get an idea of who you were. The phone interview obviously took place under the eye of a recruitment agent.
Anyway, by the time you even got to the guy who offered the job, the preselection had been made. Employers didn't really have to deal with those people.
