I didn't say NOT to do it, I just think people focus too much on it. And not even the practice interview itself. I think this mindset that everyone has to have an amazing GitHub and be a rockstar 10x engineer and do tons of practice interviews in itself keeps people from applying for newer and better positions, and improving themselves on the job.
That is to say, it's a kind of meta imposter's syndrome. "I'm not even doing the right things to make myself good enough to put myself in a position to get a better job!" Which keeps people from even trying.
So, to those points, I'm pretty sure I agree with you. Curious if this is some sort of survivor bias, though. In particular, how normal are we? If we are the outliers through luck or some other factor, I'd kind of like to know.
That is, I think this somewhat describes me too. However, I don't know as that I can give the advice of "ignore practicing interviews."
