The parts I love are where I get to make my own decisions locally, with people who are directly affected (which to be fair, is the majority).
The parts I hate are those planned centrally; which thankfully right now are mainly limited to IT, budgeting / expenses, etc. You can completely tell that at the CTO level it looks like we're saving gobs of money by planning centrally; but at the local level you can see that in fact what's happening is the costs are being externalized into other areas in ways that are difficult to measure, but probably end up costing the company at least 3x.
Some of the best jobs are in remote corners of large companies, in particular something that is very needed but nobody can or want to do, and thus people will leave you alone enjoying freedom and a big company paycheck. Like dealing with the legacy system that actually keeps the lights on while MBAs are drafting strategies to build one failed system after another.
