Yeah but does anyone really in that time? Lol lmao no.

They do, I've had quite a few new teammates who've done that

They're all people who've been coding at a young age or are completely obsessed with coding and working. Like spend lots of free time reading published papers or just working more types lmao

They usually also job hop once every year or two so they're used to it

Just the most hardcore careerists you've ever seen
