Good question — and maybe worthy of another post! I’ve been fortunate to work mainly in places that are low on politics, and where playing politics is not rewarded. But any amount of politics makes it harder for the best ideas to rise to the top.
In general, I’d suggest looking for people who seem to be able to navigate the politics in a respectful way, without making things more political, and see if they’d be willing to help you. The political environment at each company is unique, and understanding all the dynamics is incredibly challenging.
