Even job fairs are useless now. I'm a current student and when I show up a lot of companies seem to just send an intern or 3rd party recruiter out with a bunch of generic company fliers. You can't ask any questions about the job because the recruiter won't know the answer, they don't work in the department or even worse they don't work for the company, and when you find a company you want to join they tell you to apply online anyway. Sometimes you get a special link for applying, which I think is how they differentiate between job fair applications and the others.

At least the few smaller companies that show up seem more immune to this, but they have the problem of wanting to pay an electrical engineer about $50,000-$60,000 for starting pay, which just isn't worth it. So everyone still puts up with the recruiters that know nothing because at least then you have a shot of earning a market rate salary.
