[Question] How do you concisely communicate & navigate the politics /​ culture at your job working at a large corporation or institution?

Previously I’ve worked at small companies and state government or educational institutions. Now I work at a ~30,000 person private corporation and need to better adapt to that cultural situation.

My biggest cultural struggles so far are communicating concisely to people at multiple levels in the hierarchy across multiple different teams and knowing how to navigate the politics of a large corporation (I’m not used to directors being meaningfully different from managers, or the massive differences between what’s called “upper management”, “management”, and everyone else).

I work in a technical role and support customers across every rank & role in the enterprise.

What are your tips, tricks, and advice for handling concise communication & navigating politics /​ the culture at a large corporation or institution?
