If I started a new business, excuse me Start-up, which college applicants hide in for 4 years would have no bearing on my new hires.
And yes--I'm the guy who spent way to much time hiding in college. It was cheaper in the 90's though, and I lived with my dad way too long.
One if the best at your school doesn’t mean one of the best at uni though! And I realised while I like maths, it is the maths you can visualize. My favourite was calculus and learning about limits! Just imagine it getting smaller right. But then it got more and more abstract. I lost the love of studying it and the intuition.
So in a nutshell I am saying Dunning-Kruger. But I could have been just a good coder if I got a job with other coders to learn the craft and nothing beyond 0-16 yo learning. I would have self taught stuff to the same difficulty as the 16-21 yo learning but on applied topics. Learning Windows internals for example or Linux - depending on where the job took me.
