Congrats.
I'm an employed dev who worked with C++, Java, C#, JavaScript, Python, Lua etc for a few years now.
I don't consider myself knowing any languages.
If you ask me about syntax for a particular reason, I would look like a newcomer to programming.
What I know, however, is the flow and the general design of the code, async callbacks (API calls are very common), low/mid levelish programming (robotics), pointer management (whether to make a pointer null every loop to save RAM or just pack them into a god class and let it stay for readability?)
Whatever I get told to code in, I do it.
This is the case in small companies.
With the market saturation, you don't really get to choose the language. My language was JavaScript, but my first job was Java.
If you work for very small companies, you can be told to "research" (euphemism for ownership; every bug will blamed on you) exotic tasks like Unreal Engine, drones, android apps, especially for takss shown to many people in conferences. This is particularly worrisome because a crash means embarrassing your company in front of thousands of professionals, or crashed drones.
