When looking at a resume, it's easy to understand how prospective employers will assume someone is very intelligent based on their education and past experience.
But one shouldn't only assume someone's intelligence based on what they read.
More often than not, one can tell rather quickly that someone possesses above-average intelligence, based on how they speak, how they behave, or other telling details.
Redditor PadWanKenobi was curious to hear what people felt were the tell tale signs they were in the company of a possible genius, leading them to ask:
"What’s a sign of extremely high intelligence?"
Instant adapability
"Ability to intuitively and quickly understand complex systems and how lots of parts relate in a coherent whole."
"Like I work with some people who just keep tons of concepts in their head and easily integrate new information into their understanding of those concepts."
"They immediately know what questions they should be asking to better understand."
"And these are things they're currently working on, not like things they spent time studying in school over years."
"They just have a very strong ability to synthesize new information into their understanding."
"I sit in meetings distracted and confused having forgotten what we talked about in the previous meetings, and these folks just consistently have a solid handle on everything."- Ok-Control-787
Innate Problem Solvers
"They know when not to solve a problem."
"This took me a while to understand but the smartest people I know do this."
"It could be a really simple thing like ignoring emails from people asking for help."
"The supervisor or boss might have a quick and easy solution for the situation but instead of just handing it to the person that asked they let them figure it out on their own."
"They know who they can do this with and when to do it."
"If they did that with all of their underlings it would just create a mess."
"Another example that I can think of is planned chaos."
"Some people can predict exactly where things will go wrong and they could fix it before it creates a problem."
"They don't because nobody ever notices what's going on in the background when things are working perfectly."
"Once things fails then everybody notices and if you are the one person that fixed it you become the hero."
"They can also use then chaos to reach a goal they couldn't get before if things were working correctly."
"There's many examples of this in every day life that I didn't see before until I realized what was happening."- atapes

As many people are masters at appearing much smarter than they are.
In fact, one important sign of super intelligence is being able to separate those who appear smart, from those who actually are.
