Super-smart coworkers. Managers are quite savvy technically; all I've seen were hands-on engineers themselves. If you don't like this, you might like that. Tons of opportunities to transfer, and this is encouraged. Almost fully remote (thanks, COVID).

A quagmire of codenames and lingo.

Many silly ops problems during onboarding (thanks, COVID). Get on top of that and don't wait for someone to fix it for you. If you want it done, you're going to have to do it yourself.

An ocean of info in Confluence. There is no means of knowing what is old/outdated other than personal suspicion. Healthy skepticism is advised.

A myriad of systems and processes. If you do not do it correctly, you will simply be met with crickets and tumbleweeds. So you have to proactively check on progress to see if you need to do things differently.
