Answer
Personally I've never seen recruitment methods used for un-skillled workers. What I have seen is ads in a Newspaper advertising for un-skilled workers and the rate they will be paid per hour.
Usually large companies don't bother with big recrument efforts to hire un skilled workers, its not worth their money. It's when they want Chartered Accounts or something along that line, that they put out big bucks for recruitment.
