i want to say something that sounds cynical but is honestly a load off my shoulders: at a holding company, the brand on the building is a variable that barely matters. Past the exec layer, every one of these shops runs the same logic. same offerings, same trimming of the same fat, same dysfunction. the inputs that actually determine your experience are your team, your client, your manager, and maybe the company president if you're senior enough to ever interact with them. That's exactly why nobody here can predict what your run will look like.
what you can control: treat the first month as a discovery phase. map the team, learn how decisions actually flow, figure out the promotion cycle before you build expectations around it. Managing up is the highest-leverage skill in that environment and nobody teaches it.
a stable seat in this industry is worth something right now, so don't undervalue just having it.
One last thing: delay judgment. Give every person and every process a few weeks before deciding you hate it. Half the time the friction is onboarding noise, not a real signal. Be a good teammate, keep observing, and act on the actual data once it comes in.
