Besides finding the work incredibly unfulfilling, I'm concerned that this entrenchment will prevent growth of the company in the mid to long term. I am also concerned that as a fairly senior person (and having held a senior position prior), will be unable to meet what I consider the correct level of effectiveness for someone working at that level.
Onboarding besides the basic company introductions was very thin. The OG's don't have a team building mindset. I think it's probably more of a nuisance to them and they expect information to flow through question polling and osmosis.
I want to find a way to become an effective contributor to this team and someone who can lead and contribute a wealth of knowledge, but I feel that the OG's have reached a knowledge escape velocity that I will never be able to catch up with. Suggestions?
