Pros: Microsoft offers excellent pay for relatively inexperienced developers. Even as a junior developer, I was given responsibility, but I always had a mentor to aid me when I didn't know what to do. I shared an office with another developer, but I can't think of any engineering positions that had cubicles or open floor spots. There are many training sessions occurring, and career progression seemed like a very formalized system. It's easy to see what you need to do to advance. Self-evaluation and goal setting are encouraged by managers. These goals and evaluations are used when determining bonuses or career progression.

Cons: Some of the internal systems seemed a little archaic. Internally, open-source software, libraries, or tools were viewed as hostile, or at least with suspicion. I needed legal approval to use jQuery. My development computer was slow, even if I had a pair of nice monitors. 1 GB of RAM was terrible! A few of the employees seemed somewhat uninterested in their work; it was definitely a day job for them. Benefits, like leave, are tied to how long one has been an employee. Setting up an environment was not documented well in my team, and it was common for existing employees to not be able to help with this.

Pros: Great teams, and I personally had a great manager!

Cons: 520 traffic can be a bear!

Pros: Good compensation, talented co-workers, and a plethora of opportunities. Generally positive work environment, though this can change based on the team you are on.

Cons: Management is focused on re-organizing the business and has lost touch with the market. Lots of people are moving around right now, and projects are being shelved or killed left and right.
