Pros
The product is amazing. You really feel like you are working for a company that has the potential to change the world. Everyone at the company is open and welcoming - senior exec leadership encourages rank and file employees to contact them any time, and even thoughtfully reply to e-mails from new hires. The "creature comforts" are on par with Google - fully-stocked microkitchens, amazing food, and on-site fitness classes and massages.
Cons
Lots of hard work to be done, and the expectation is that everyone is ready to roll up their sleeves and get to work. There is no coasting at Twitter. Although the leadership team has a strong plan to re-ignite growth, it may take some time for revenue to materialize and the stock to recover. There's also always a few growing pains at companies growing as fast as we are, so employees are expected to navigate an environment with some uncertainty. Also, the company is strongly biased towards e-mails and meetings, which could be a shock for folks from smaller companies.
