> I feel its a very telling skill of engineers whether or not they can communicate issues in an effective manner urgently and figure out the best course of action to unblock.

I could be this person that appears not communicate, but the reason is because I've never had a manager that could unblock me faster than if I didn't tell anyone and just did it myself. For the longest time, every manager I've ever had was mostly useless (for unblocking some issue), it took quite a few years before I got an EM that actually makes shit happen. Only then did it become a habit I had to break.

It doesn't make sense to tell someone who can't or won't help you that you're blocked on something. Eventually you just default to never asking.
