I realize this thread is a month old but it is still relavant. I have been doing applications and sending resumes and still no calls. The school semester is almost over but at the same time I will be here next fall to work as well so it wouldn't be that temporary of a job.
How's your resume looking? Is it more than one page? If so... cut it down to one. Long resumes tend to get sidelined. In this country you can call jobcentreplus, give them a top three list of what you want to do, like admin/retail/bar work of something, and they'll frequently send you letters, call you, and send emails for the jobs that suit you the same day they come in. S'a good service. You probs don't have it there, though.
My only advice is hassle people. Better to hassle in person, while dressed well. You have a CV, walk it into the building and talk to the receptionists when you hand it over, be personable, looks better than sending it in. Ask to fill in application forms while you're there in the reception, make small talk. The receptionists are often the best known people in the place, and they will mention you when they encounter a boss or something. Call up employers, and talk your way from the receptionist to the human resource department, ask about the kind of people they're looking for, tell them you're interested in the company, and would like to know what you can do to improve your chances of becoming an employee. "Any particular qualifications or skills I should concentrate on?" If you're keen enough and they know that they may just grant you an interview just to see what you're like. If you get a reply from a prospective employer telling you your CV and application is on file, call them every two weeks to follow it up. Don't let them forget you.
Doesn't matter if its an office or a shop or whatever, talking to the staff in a shop, about 'whatever' while you're asking about work, will get you put ahead of people who have their applications stashed in some drawer somewhere. I'm pretty good at getting jobs, I just blow at keeping them. (I've quit jobs just to play a new game.) lol You are the product, and you're the salesman too. Nobody knows the product better than you, and all you gotta do is understand your customer, make your sales pitch, and make the product something they'd like to have around.
