Here's what Elon Musk, Richard Branson, and 28 other successful people ask job candidates during interviews

Savvy executives know that interview questions like, "What's your biggest strength?" and, "What's your biggest weakness?" aren't as telling as they seem.

That's why they steer clear of these cliché queries and instead ask more meaningful ones.

Many of the most successful execs have their one favorite go-to question that reveals everything they need to know about a job candidate.

Here are 30 of them.

'What didn't you get a chance to include on your résumé?'

Virgin Group founder Richard Branson explains in his new book "The Virgin Way: Everything I Know About Leadership," that he isn't a fan of the traditional job interview, reports Business Insider's Richard Feloni.

"Obviously a good CV is important, but if you were going to hire by what they say about themselves on paper, you wouldn't need to waste time on an interview," Branson writes. That's why he likes to ask: What didn't you get a chance to include on your résumé?

'Are you the smartest person you know?'

As Dartmouth business professor Sydney Finkelstein describes in his new book, "Superbosses," Oracle executive chairman and CTO Larry Ellison makes a point of only hiring exceptionally talented and extremely intelligent employees, and consequently coached his coached his recruiters to ask new college graduates this question.

If the candidate answered "yes," they'd get hired. If they answered "no," the recruiter would ask, "Who is?" Then they'd try to hire that other person instead, Business Insider previously reported.

According to Finkelstein, superbosses like Ellison are confident enough in their own abilities that they aren't worried about employees outshining them, and they aim to hire people who are more intelligent than they are because those employees will challenge them to come up with better ideas and solutions to problems.

'On a scale of one to 10, how weird are you?'

One of Zappos' core values is to "create fun and a little weirdness," Tony Hsieh, CEO of the company, tells Business Insider.

To make sure he hires candidates with the right fit, Hsieh typically asks the question: "On a scale of one to 10, how weird are you?" He says the number isn't too important, but it's more about how people answer the question. Nonetheless, if "you're a one, you probably are a little bit too straight-laced for the Zappos culture," he says. "If you're a 10, you might be too psychotic for us."

Another question Zappos usually asks candidates is: "On a scale of one to 10, how lucky are you in life?" Again, the number doesn't matter too much, but if you're a one, you don't know why bad things happen to you (and probably blame others a lot). And if you're a 10, you don't understand why good things always seem to happen to you (and probably lack confidence).
