I could be wrong, but it was always my understanding that career services wasn't supposed to get you a job. They were supposed to show you how to write a resume, go on interviews, things of that nature. Maybe show you fields you can apply your degree in. But finding and landing that job I always thought was supposed to be up to you.
Yes. Now, granted my school is a state school with around 25 - 28,000 students counting graduate students in any given year. It's also a party school, and not top of the line, though not a piece of crap either. Still, career services here put together databases so you can post your resume and try to search for companies that would be good fits. Companies can also search for you. But otherwise, they do interview prep including taped sessions to help you get better feedback, things like databases and career coaches to help you figure out what sort of field to search in, etc. They do a series of workshops on how to deal with a shitty job market in your senior year of college, the various stages you should go through, etc. They look over and advise you on your resume. They do career fairs several times a year to bring companies onto campus so you can go to them and apply for internships and jobs. They try to partner with businesses where they can. My school has a connection with the FBI because we have a center nearby. They always come to campus to recruit. We're not special -- we're on par with our peer institutions in this regard. At the college level, there are even more things built in for career prep -- if students sign up for them, go to the job talks or go actually meet the person brought to campus. But ultimately, students have to at least go fill out the application or even more basic, they have to show up. And at my school at least (granted, it's a big party school, but it still has research honors, notable alumni and various other rankings), that's still not happening nearly like it should.
And Smurfette is right -- it's definitely more difficult nowadays to walk into that job after college, though I would posit that was originally mostly a myth anyway. If you had prior connections, college was just a stepping stone. If you didn't, you looked, applied and competed for one like everyone else, it's just that more people were hiring and not being stingy with salary. Everyone seems to agree it's harder now. Which makes it all the more perplexing that more students aren't looking for that edge, wherever it might be. I know I didn't when I was a senior in college.
