It can be as simple as saying hi.
I get a lot of praise and “wow”s when I mention the amount of companies I’ve been getting in touch with lately. And yes, it most certainly sounds impressive to say “I have three appointments with various companies this week, and two more next year”, but they’re just that: appointments. Little talks to get to know the company, have them see what I’m all about, that kind of stuff. I’m being asked largely based on the fact that I am an IT student. That’s it.
But the companies didn’t just randomly call me one day. Contacts don’t fall from the sky like that. I actually forced myself to network as best I could. Apply to meeting days, conventions, and go chat with company recruiters. Give them your business card, resumé, make sure they can find you among the other people they talked to. Then, wait and hope for a call.
That’s about the best advice I can give right now, be pro-active. Also, work in IT.
