I would suggest reading business papers/magazines to find out which tech companies are really growing. The company I'm doing my internship with grew exponentially over the past 1.5 years and hired about 67 people in just a few months. I've heard stories that five friends who just graduated all submitted their resumes to the company and four were hired.
Also, take note of which companies are going public. The company I work for went public last year and therefore received a huge influx of money to pay for the 67 new hires.
I guess this doesn't really answer your question, it's more of a tip when job hunting.
