Among college graduates ages 22 to 27, computer science and computer engineering majors are facing some of the highest unemployment rates, 6.1 percent and 7.5 percent respectively, according to a report from the Federal Reserve Bank of New York. That is more than double the unemployment rate among recent biology and art history graduates, which is just 3 percent. “I’m very concerned,” said Jeff Forbes, a former program director for computer science education and workforce development at the National Science Foundation. “Computer science students who graduated three or four years ago would have been fighting off offers from top firms — and now that same student would be struggling to get a job from anyone.”
