Daniel Haarburger always asks job candidates a simple, common interview question: What does your day-to-day life look like? One candidate gave him a textbook example of the "worst response that I've ever heard," Haarburger, the CEO of Denver-based dog toy company Woof, tells CNBC Make It. That was someone blatantly saying, 'I don't know what the hell I'm doing.'" You do need to be honest during job interviews, Haarburger notes. Haarburger offers another piece of advice: No matter what you say, keep your demeanor and body language consistent throughout your interview.
