I've said it before on here: being a lower-level manager in a large company is worse than an entry-level job.

No one cares about your job experience (all those painful internal tools you now have to use to manage and report on your team) so you're just expected to grit through all the broken processes and inefficiencies (kiss your evenings and Sunday afternoons goodbye), and you are mostly powerless, particularly in orgs with centrally managed budgets.
