It's more possible at giants, IMO. Level of technical competence/excellence tends to be inversely proportional to company size. FAANG might be exceptions, but IMO large companies (like big banks, etc) have a lot of hidden technical incompetence you can't see.
A major goal of the complex computing infrastructure at large orgs is to wall off the ignorance and/or incompetence to contain, mitigate, or prevent its consequences.
(Note that "ignorance" is not pejorative here: not everyone can know everything.)
