Steve Jobs once revealed the number one sign that means someone has high intelligence.

I think, we all have an idea of what makes someone smarter than the average crowd.

Whether that be stellar general knowledge or just common sense, everyone has their opinion.

Well, Steve Jobs was certainly a very intelligent man after investing and running the juggernaut that is Apple.

Of course, Jobs' journey with Apple was somewhat down to luck, as he was there with an innovative product at the right place and the right time to capitalize on the market.

Jobs, who died in 2011, had to be clever enough and have the know-power to execute his idea though - and he certainly did that and then some.

So, what did Jobs feel was the best indication of high intelligence?

Well, in a speech to the Academy of Achievement in June 1982, just six years after Apple was founded, Jobs said: "A lot of it is memory. But a lot of it is the ability to zoom out, like you're in a city and you could look at the whole thing from the 80th floor down at the city.

"And while other people are trying to figure out how to get from point A to point B, reading these stupid little maps, you can just see it in front of you.

"You can see the whole thing. And you can make connections that seem obvious to you, because you can see the whole thing."

From Jobs' time running Apple, we know all about the 'beer test' interview technique.

While deciding on candidates, Jobs asked them to take a walk and even enjoy a beer with him, in the hope of helping them loosen up while he learned more about them.

So, rather than grilling potential employees in a stuffy office, Jobs decided to make things a lot less formal.

When Jobs got interviewees down the local boozer, he would reportedly ask them questions such as: “When was the last time you accomplished something?”

And a more simple and talkative: “What did you do last summer?”

The aim with such an unusual interview technique you ask? Well, to essentially find the very best of the best, the 'A-Players' as the Apple co-founder once put it.

"I found that when you get enough A-players together, when you go through the incredible job of finding these A-players, they really like working with each other," the Apple founder previously explained.
