I'd like to add that, what you are describing, sounds like a pretty hostile environment. Luckily, I made the opposite experience. However, it also requires that you, the developer, are open and curious about the motifs that the C-Level has. Sure, you can sing the tantrum that you cannot estimate times - and I agree! But it helps to ask what they actually need, and why they need it. Maybe you can come up with better ways to help them get clarity. Remember - from their standpoint, it's all a big black box they cannot understand.

From my experience, execs want to know the current state, and also want to be able to intervene before a project derails. That's usually accomplished by open and coherent communication - a skill that is yet to be found by some developers. But you can work on it! ...if you want.
