I've for mega corps as a manager and now a tiny company. Both have strengths and weaknesses. It's baffling to come from that environment and see the lack of tools or standardization for example. It feels like things are being run backwards.

That said there's less stress, less micro management, people are generally nicer, you can reach the person you need without 18 fucking middle manager and gate keepers, you don't waste half your day on lectures and seminars on the newest buzzword campaign.

Smaller companies generally are better but have their own set of pitfalls.
