About 700 people filed into the Hilton Concord on Tuesday in order to take the exam required to become operators or maintenance workers at the Chevron Richmond Refinery. The applicants were among thousands to express interest in applying for just 65 full-time positions. These jobs earn upwards of six figures and require from applicants only a high school degree (or GED equivalent). For many, this will be a life-changing, career-making opportunity. We wish them luck!
