Having worked in both of these situations, I completely agree with this post. Even with the adoption of "Corporate Agile", our large teams were not able to get near the efficiency of a smaller 4-6 man team.

A 100 dev team is usually hiring by resume via HR with less focus on culture fit and in-depth technical knowledge.
