Pros
If you work hard you will be successful. If you have a thick skin, even more so. Lots of company growth which allows for upward mobility. There are many additional perks in the form of food, prizes, off-sites and so on.
Cons
Despite many bright, talented and insightful people in the senior management roles, the very person at the top of the chain governs by principles of rash decisions, closed-mindedness and bull-dogging. Rather than internalizing feedback, promoting innovation and encouraging constructive changes, he communicates a generic, "salesy" message that wreaks a callous, insincerity. What once was a fun, challenging, flexible work-environment, has now become a stifled, confined, corporate cog of a workplace that is gunning to be the next big thing, with little consideration as to how to retain the people that make the company thrive. It feels like a dictatorship. Where's the democracy?
