Ask HN: How to cope and adapt to a complex tech company?

Hello HN,

About six months ago I started a new job at a "real" tech company after a decade working in startups, scale-ups, and relatively "non-tech" tech companies. Now I work in an org with hundreds of services, many teams from acquired buinsesses, and a mountain of terminology and acronyms. There is a lot of context switching.

At the same time I've been battling insomnia, which is impacting my memory and recall.

Basically I am looking for systems, techniques, tools to cope with a complx environment whilst operating at less than my best.

I've been using Obsidian and paper notes to capture information but to be honest it has devolved into chaos.

What do new joiners at big tech orgs use to manage their knowledge?
