Pros
Competitive salary and interesting, large-scale problems,
Cons
The management chain is a series of folks promising the impossible to their manager, all the way up from line manager to C-suite. This will become your problem, either via impossible deadlines, accumulation of crushing technical debt, or whole-sale restructuring of entire orgs to facilitate a C-suite promotion or fulfill a promise to lay people off. Also, effectively uses stack-ranking for perf reviews. Expect to do an adequate or better job and receive a 2 if you're unlucky, or, as a manager, expect to be pressured to give your worst-performing-but-capable staff 2's (or most absent - strange trend of people returning from sabbatical or paternity/maternity leave receiving 2's! funny, that!).
