Upvoting you to help prevent your comment from reaching oblivion - I don't agree with you, but I think what you said is a common belief.
The thing is, it's a vastly different kind of pressure. When I am coding as part of a job - by myself or with others - there is no inner monologue in the corner of my brain doing something like this:
"Could do that or... no damn, that's O(n^2), damn I'm taking too long that one looks bored, if I instead put those keys in a hash... no, I'm sure there's a better way, running out of time though, is he looking at his phone now? Okay, what was the profile of merge sort again? ... oh, shit! She felt like she had to offer me a guiding hint, I'm doing it wrong!"
And it never stops going. It picks apart every choice I make, and by five minutes into the interview I come across as a sub-articulate mess.
In no other high-pressure situation does this happen to me. Hell, this past summer I actually spoke at a conference and I didn't have the kind of trouble I do in an interview.
Whiteboarding, paired coding, participating in architecture design - these things come easily. In the context of an interview, though, it goes out the window.
Have you done pair programming before? Especially as you become more senior, the pressure to not look like an idiot in front of junior devs adds up fast. You have to learn, quickly, how to get over that kind of inner monologue, and just get to work.
I've never felt that pressure. Keep an air of confidence. Let them assume you know way more than they do about almost anything else. They'll feel like they're really shining in this moment, and impressing you, and growing in their role. Win win.
I don't understand the desire to make it seem like you know everything.
If you learn something from someone, is it that much trouble to give them credit for expanding your horizon?
If this mindset is recursive down your organization's hierarchy, doesn't it create a scenario where a legitimate critique never gets heard because people don't question the decision of a higher ranked employee because there is the impression that they know more than you?
Seems like you and your employer are worse off, but your ego remains intact.
I do pair fairly regularly -- for whatever reason, the concerns don't manifest the same way as in interviews. I can't think of anything in my experience (professional or personal) that's comparable.
