Apparently this tech lead guy created programming videos to teach you how to get hired at big tech companies. It turned out the partner guy in the videos wasn’t even a developer but had maybe interned somewhere in data science? And both of these guys were claiming to be career professionals, as if they were staff or principal engineers.
The ads reminded me of another character from many years ago that would show off a Lamborghini or some sports car in his garage with a wall of books - another scammy self help guru.
Edit: I looked tech lead up on YouTube as I read the Reddit post and typed up this post. I can’t tell if this guy is trying to be a parody/using dry humor or if he’s a narcissist sociopath.
