Pros
Great office space, perks and compensation, trainings and workshops, flexibility in terms of dress code, work timings etc. There are some people who are smart and efficient.
Cons
The flexibility part highlighted about Microsoft is mostly on paper. Except for trivial things like dress code, work timings the important ones like flexibility to work, express, innovate remains a distant dream. Everything about you is decided by the manager. Your relationship with him and the way he perceives you can make or break your career. The work is crap and extremely mundane especially in Microsoft IT (UST). A software developer ends up spending most of his productive time in pointless discussions, activities like bug fix, deployment, design review which are not relevant to him. The managers here are mostly biased and useless.
