On one hand, I agree. I've heard people on my past teams talk like we were an ace team made of the best there is, when the reality is we were probably thoroughly average compares to any other team out there

On the other hand, I've been a part of interview processes where candidates absolutely were rejected with good reason, because it seemed their technical skills would absolutely not be up to our expectations. I think a lot of us have seen that. It's more common than we think.
