For the next two weeks, we’re focusing on job interviews. If you have an interview on the horizon, you may be asked some variation of “what motivates you?” or “what makes you happy at work?” And even if you aren’t asked one of those questions directly, you should still think about — and be able to convey — what makes you feel good about your work. Beyond doing well in your interview, knowing what makes you feel good about your work can help guide your job search.

For this week’s Video of the Week, we’re featuring a TEDx Talk by behavioral economist Dan Ariely that considers what experiments reveal about what makes humans feel good about our work. Check it out, and come back Thursday for tips for succeeding at informal interviews.
