More than 70 M.B.A. students at UC Davis will be given a lesson in business etiquette on Friday, Feb. 17, at the fourth annual business etiquette workshop. "Our goal has been to give our students a competitive advantage by developing strategies that will give students confidence and poise in their search for a job," says Don Blodger, director of student services at the Graduate School of Management. "The business school created this course because students wanted to make sure that if they were turned down for a job during an interview that included a meal, it wasn't because they didn't know what to do with a fish knife or the olive pit." The three-hour program, including a four-course lunch, is taught by etiquette expert Shirley Willey. "With an 80 percent chance that your interview process will include one or more meals, etiquette is certainly something to think about," says Willey. Thirty percent of all job-interview failures can be attributed to poor manners, she says. In what has become the single most popular one-day course in the business school, students will learn table manners, place settings and the proper etiquette for greeting international business leaders.
