Pros
I see some sour grapes on this site because some people do not always get everything they want, but across the board, I have seen more people do amazing work than any company I've been involved with. The level of quality at this firm is amazingly high. To get noticed, your work must be truly exceptional and the culture is one that people are excited to show what they are capable of. Top performers are rewarded appropriately. Anyone who does outstanding work will be recognized. That sounds obvious, but it is amazing how many people blame external factors instead of focusing on their skills and contributions. People at this company help each other, even if they are not directly involved on the same team. Generally, they take time out for each other. I saw some complaints about career manager interaction. Contrary to what others have said, career managers are very involved with the performance of each person, even if they do not work with them individually on a team. Management is very tuned into individual performance even if they are not sitting next to every person every day. More often than not, it is the individual contributors who do not want to meet regularly, 1 on 1, or share their achievements. Managers are always open to sit down and talk, even if people want to talk to their manager's manager's manager etc. I have seen relatively junior people at the firm having lunch with top executives. They have a great open door policy. Also, social events offer some great room for people who would not otherwise meet, to cross-pollinate and discover new ways to help or be helped. If people do not love working here, it is doubtful they will love any healthy, challenging, quality work environment. If people prefer a slow, safe, simple job, they should work at a company that is done growing. We regularly get first place for 'best places to work' in almost every city where we have an office. The leadership here are the most intelligent, involved, and dedicated that I have seen. I would much rather see team budget maintain our culture than give slightly larger bonuses to people who are at the bottom of the bell curve. We survive and thrive based on our performance every day and cannot afford to make things more comfortable for the bottom of the bell curve, even as we grow.
Cons
As the firm grows, not everybody learns the same things at the same time, so it's more difficult for everyone to stay in sync and have the same understanding and visibility.
