Pros
+Projects are often fun, engaging and interesting. +Very young organization, as an early-30 you often find yourself to be the most senior in your group. +Pretty diverse community (maybe even too diverse for some).
Cons
-Due to the average age there's not much business professionalism, which often puts the company to shame in front of partners. -Office architecture and traditions are at an incredibly low niveau. -It's a two-tier caste system with managers on the top and untouchable employees on the bottom. Those tiers can be described as separate "flat" hierarchies, but they are totally different experiences. -Lots of wishful thinking, sunk cost fallacies, unmeasured risks and other classic system issues that happen without appropriate feedback and control mechanisms in place.
