Also, this has been MY career experience to this date. As I now run my own tech companies and have been hiring technical people for the last 7 years, I have anecdotally found this to hold true. The early to mid-career types that have only ever been at tiny companies or startups are really good at having a breadth of experience and an ability to move fast. The spent all my career with big company types have usually been pretty deep at something (a language, framework, tech niche) and are very used to processes. They're typically slower and have a need to encumber small things with bloat (process, tech, etc). Marrying these people together on a team has yielded me fantastic results in nearly every case. The big enterprise people feel like they've been released from a cage, and the scrappy startup types seem a little less feral, while providing an infectious get shit done attitude.
