I am the kind of person who likes to work with small but effective teams. I like people who are willing to go the extra mile to build something cool and advanced. Although i haven't been to Google, Apple, etc but i think these companies do not leave enough room for people to explore new cool technologies to work in, which is pretty much all you do in startups.

So i'll always go with a smaller and effective team than being part of a very big company where my role is more or less insignificant.
