Put a figure; Hammering home to us - Tradução em português

To be honest I couldn't put a figure on how many jobs I've applied for, but it's a lot. Since I broadened my search I've had a couple of interviews, one over the phone. But neither has come to anything. I've just done some more unpaid work experience for a digital advertising network, which went well, so now I'm thinking about looking in that direction.
I can't really fault the university. One of my lecturers had experienced a long period of unemployment and set up careers workshops, hammering home to us how hard it was. But nobody I know who did my course is doing a job they want to be doing. They're all waiters, or working in shops.
