Word choice is a factor when considering how to write your resume, speak to a recruiter, or communicate in an interview/at the job. I’ve found some people see that I can overthink factors/details, but asking productive questions with an attitude that I don’t know everything can contribute more effectively to building a team network.

I have learned the art of displaying intelligence only when it is an asset to others (it saves the day for someone else). I dumb down my explanations and make them approachable, I don't use jargon or play master of the universe. I never humiliate anyone. You probably need to think about your desired "branding" so to speak, and tune it so as to be palatable in various contexts you need to function in.

Working with others is not a zero-sum game; you can shine in ways that help others to shine.

I always use my intelligence to make OTHERS look good and/or to prevent THEM from looking bad. If your boss knows that you have their back, they won't fear how you might go behind their back to undermine them. This makes me someone who is smart and on their side, rather than someone who is smart and disdainful.

I guess what it boils down to is that if you have, say, a 150 IQ then based on the bell curve you're going to be smarter than 99% of all other people and you'd better learn to be damned humble if you want to get along with all those people, have them be happy to pay you lots of $$, etc.

You can’t give most bosses the impression that you’re smarter than them; unless they are half as smart as they think they are, they see highly intelligent people as red flags more than assets. Most of them want people who are smart enough to do as instructed yet not smart enough to make any waves. Thinking outside the box is unpredictability.

I kept trying to get a job at an office or electronic big box store: office or Home Depot, Best Buy etc but I can never pass their subjectivity test. They have you answer a hundred or couple hundred questions which are actually the same 25 questions about how you’d handle certain situations, rephrased differently over and over. They’re looking for mindless consistency but to my intuitive brain, the different subtexts that result from the different phrasings always make me read between the lines enough to change my answer. They don’t want anyone who makes subjective decisions to the point that I couldn’t even get a job there when I had an aunt working there. Not even nepotism could defeat their intense desire to hire a basic bitch.

It could be that the person hiring is threatened by you. What I've found makes an ideal staff are people who are smart; have a good work ethic and as importantly who have a good attitude (team player, a sense of humor).

Do you think that you are more intelligent than other people? Why?

Higher intelligence is seen as a threat, moderate but controllable competence is all that is desired by most employers.
Intelligence almost always equals ambition.
It is no surprise that the phrase "To clever for your own good" has been so popular for so long.

Let me have men about me that are fat,
Sleek-headed men and such as sleep a-nights.
Yond Cassius has a lean and hungry look.
He thinks too much. Such men are dangerous. JULIUS CAESAR Act 1 scene 2

To be thus is nothing,. But to be safely thus. MacBeth Act 3 Scene 1

My job is about intelligence and knowledge. I constantly feel that the most stupid person in the room. Be proud of yourself you have nothing to prove.

I don't know of your personal experience, but maybe you come off as a know-it-all? Some think of me that way. If you correct someone, they think you are being a smartass.

Here is a job where they want you to be dumb. A service advisor or used car salesman is an example. These people have a job to sell things. When the economy was bad, I was looking for a job. Couldn't get a job as a used car salesman. Why? I know too much as a Ford and ASE certified mechanic with an AAS. If you try to sell a car the customer would ask something like "are these good cars"... well they are known to have (whatever) fail. Same with a service advisor. I had one that went straight from wash boy to service advisor. One of the other mechanics yelled at my boss because he had to explain to him how an EGR valve worked. The boss flat out said he wanted to keep him stupid. Not joking. This service advisor also gave me a ticket once that said "engine loosed oil pressure when engine is off". No. Fucking. Shit?

My observations are that they don't want really smart or the opposite. They want middle ground and easily controlled and manipulated. Anyone who sticks out, intelligence/originality etc is seen as dead weight or worse.

The reality is yes, your intelligence is an asset, but even more important is the way the new employee will work well with an already established system. Think about a basketball team recruiting a new player. The skills that are needed to play the position is already understood. What is needed is a player that can come in and work with the system in place. Can they get along with their teammates or is the new player going to upset the team chemistry? May sound silly but relatability is important. Asking questions about the dynamic of the office or organization and how different roles interact gives the person doing the hiring an understanding of whether or not the candidate sees the bigger role outside of the skillset, and helps determine whether or not spending the money and time to train the new employee is worth it. I'm an introvert, and I hate this part of the process but it is extremely important. We will spend more time at our jobs than with our friends and families so hiring someone to work next to you that can do the job AND get along with is just as important. At least that was my experience when I did the hiring.

Companies often don't want to employ someone who is overqualified for different reasons.
