Its not that hard, the core of programming is the code-debug-fix cycle.
That is something people can take with them no matter the job or the programming language. Pretty much comes down to where to put break point, print statements or how to setup traceable logging when working in multi services landscape.
Knowing this cycle well you're already effective when starting a new job.
Want to start even faster keep your tools limited and multi platform, lets just say your tool set shouldn't exceed a post-it note using big letter sizes.
The rest is domain knowledge something you will pick up over the coming months or years from colleagues and be paying attention at refinements and other meetings.
This is mostly about software development jobs/gigs, if you're doing some STEM job in nuclear reactor design etc then yeah thats a completely different story.
