Why Projects Work Better than Interviews ?

Can you really find out what you need to know about a job candidate in an hour-long interview? Probably not. No amount of interviewing, reference checking, and psychological testing is a substitute for actually working with a candidate on a real project. Next time you're hiring, consider giving your top candidates a constrained project to execute.
Ask them to redesign a social media campaign, document a tricky bit of software, edit a keynote presentation, or produce a webinar. Look at the results and decide which candidates were able to deliver real value. This doesn't just benefit you as the hiring manager. Candidates will learn what it's like to really work with you and your company.
