21． Look people in the eye.Smile.Shake hands.Sit up tall.Speak confidently.That's the last-minute advice Professor Paul Calhoun gives college students before they head off for job interviews.The Skidmore College seniors he's talking to are dressed in suits，dresses and heels.They stand out in a college library with other finals-takers，most in sweatpants or T-shirts.
There isn't an actual job interview，just a satisfactory or unsatisfactory grade from a popular，semester-long class called Presenting the Brand Called Me at this college in New York.
Calhoun created the popular，semester-long course 10 years ago.He'd spent more than three decades working in the banking industry，where he saw the importance of presentation skills： "A lot of it is acting."
When Calhoun came to Skidmore as a business professor，he noticed a lot of students struggling with self-confidence and public speaking.He shaped what eventually became this class with the help of theater professors，in order to give business majors "the same training that the theater department gives to actors".Over the 13 weeks，there are dance classes，role-playing，and a group of guest speakers who talk about cover letters and resumes （簡歷）.By the end of the course，students leave with a "STAR" story — the short story about yourself and your abilities that's designed to help land you a job. "People don't remember when you tell them you're good at something，" Calhoun explains， "they remember when you tell them a story that proves you're good at something."
Dante Delemos is a junior business major，soft-spoken but confident.He says this class has helped him realize that telling a story — his story — has value，so he uses it whenever he can：in cover letters，to shape his resume and during interviews.And it
did the trick.Delemos is spending the summer working in finance，with an internship （實習） in Manhattan.
