I don't mean to shame anyone for learning new information, but even if you have no interest in management, your career will benefit greatly from knowing the terms and concepts that managers in your industry commonly use. There's a lot of people out there who are aggressively against learning "corporate jargon" and then find themselves lost trying to understand why their company's leaders talk and act the way they do.

When I was hired at my current role, it was clear to me that I'm in an IC vs Management position. It's really not that weird and is a very common term.
