In a slowing U. S economy, job opportunities are shaped by uncertainty. As president of a small college, I am keenly aware of the job market that awaits this year’s graduates. The recent news that Bear Steams was nullifying a few hundred job offers to business school students fits a pattern of corporate downsizing that isn’t lost on college campuses across the USA. But even with the darkening economic clouds, rays of good news await this year’s graduates. Sure, companies are laying off workers, but many are also looking for new talent, especially at the entry level. As more than a million entrants flood the job market, students should know that in a global marketplace, language skills will go a long way. So will flexibility. If a grad is ready to accept an entry-level job, give a little on job requirements and move d the company asks, chances are he’ll land a job. So despite the rising job losses, a new graduate should embrace the market as the first challenge of a long career.
