The epitome of office politics. If you play politics well, you will thrive. If you detest office politics, don't think about joining - you'll drown. If you're happy keeping your head down and working years without much upward movement, you'd be OK. If you play your cards well though, you'd be promoted really quickly.
No proper onboarding system. You're essentially thrown into the deep end of the pool and expected to swim - figure everything out on your own.
Matrix system. Expect an insane number of stakeholders in every project - you'd need everyone's buy-in and please everyone. This makes things move incredibly slowly.
Everyone wants to shine so everyone wants to start their own project. This leads to a mess of multiple meetings and projects that overlaps (and you start to wonder about the purpose of it all). 90% of my time sometimes an entire day is spent in meetings and telcons.
You work in teams but beware. No one will give you credit for your ideas and your creation. People WILL take credit for your work. Don't expect recognition for your contribution. This in particular disgusted me.
At the end of the day, NO amount of MONEY OR BENEFITS makes up for all these.
