Pros
Having had the displeasure of working for some of Berkshire's competitors, I can confidently say Berkshire doesn't just push out empty talking points and goals and expect employees to conform without management's support or guidance. Berkshire engages its employees, gives direction and helps employees plan on how to achieve individual and company goals, and cares about the communities where its people are based. Berkshire talks about cultivating it's culture, but not in a "creepy" or "culty" way (I have not seen any Kool-Aid in the break room:)). You are not expected to blindly conform to Berkshire culture, rather, your individual personality and perspective are seen as an addition to the culture that evolves as the company grows. It's a very positive place to work. I don't ever close out my day feeling like the concerns I may have are being ignored or my contribution isn't valued.
Cons
No place is perfect, and refreshingly, Berkshire doesn't try to be. The company is growing quickly, and with that there are growing pains. Thankfully this fact is not being ignored by management. I am confident the company will use it's resources and engage employees on how to best address these growing pains.
