Software engineers, what did you wish you knew before joining your company?

BTW, I saw the green name, welcome to HN! I feel if the title starts with "ASK HN", you might get more responses.

The team you will be joining will make a way bigger impact than the company.

True, I believe this. The question was more what do you wish you knew about your company, i.e. is there anything you were disappointed about that you wish you knew before, i.e. poor coding standards, poor management etc

coding standards, validity of the bullshit that recruiters were spouting and whether the managers were competent or not.

Coding standards are probably a myth.

At my company they are enforced with a linting profile and commit hooks...your PR will be rejected if it is not formatted according to standards. For code structure, PR reviews will catch bad practices and when building new functionality an architecture review is required. Coding standards are not a myth.
