So, I am senior software engineer, got hired into this company. I was tasked by my manager/tech lead to work with another senior software engineer.
Overtime I realized that this engineer did not have the proper background in this field. I asked him and I asked my tech lead, and confirmed he did not have background in this field. This guy just roped into this project and stayed.
I sent him articles, tutorials, and even documentations that say so and so is so and so, but he refused to believe it and said it was just my opinion. I even offered to work on these problems instead of him. But we ended up getting into heated arguments. I talked to my tech lead and my VP and they just brushed me off. It got so bad that I asked to be transferred to a different team.
I also realized later that my tech lead was not as technically competent as I hoped to be, so that's why he couldn't make a decision.
Anyway, I asked Reddit and TeamBlind how to best deal with this kind of situation. (In those forums I actually described exactly what were the problems)
To my surprise, a lot of them, 99% of the answers go along these lines "Who the fuck cares man, just get your paycheck and go home, what an idiot". These are highly paid FAANG engineers.
So, that was my wake up call. They were right. Who the fuck cares. Just get my paycheck and go home, and work on other stuffs, work on side projects, side hustle, and go Leetcode.
I was 8 years too late into the industry to know that this should be my default attitude when working.
Now I am in "Who The Fuck Cares" club.
They gave you terrible advice. Vote with your feet. Don't enable posers. Find a better team or a better company. It takes time but it's possible. And when the new place drifts, vote with your feet again.
But remember to keep quiet about it. If all the competent people did this, natural selection would do its magic.
