You learn a lot more about the process itself in smaller companies across the board. In larger companies that only happens in the higher level roles. In larger companies your secondary and tertiary skills also become significantly more important.

Ultimately I prefer working with people that have experience in both.

Engineers who've only worked in smaller companies tend to be harder to work *with*, on a social inter-colleague level.

Engineers who've only worked in larger companies tend to be less capable when left to their own devices, they need more help if there is less demarcation. Engineers who've worked in smaller teams tend to pick up the slack proactively, from larger teams retro-actively.

At least that's been my experience both from within as well as without. (Currently working for a small company that has large corporate clients, have worked for small and corporations before that)
