Pros: You will get decently good pay. Reputed Company.

Cons: Pathetic work culture, bad work-life balance. You work as labor, just following the manager's orders. All the decision-making on the projects is done by management without much involvement from the engineering ICs, who are just handed over tasks to be completed. There is a lack of transparency between management and the ICs. You don't grow as a person, but only as a resource. Much of the soft skills you gain are not over managing projects, collaboration, innovation, or leadership skills, but over pushing your work to someone else, negotiating on timelines, and the amount of work. This type of work culture is simply not acceptable from a large and reputed organization like Microsoft.

Pros: You will find really passionate people around you, and you will get to learn a lot from them.

Cons: Recently, a lot of changes have been happening, and you might find it difficult to adjust.

Pros: The greatest pro of working at Microsoft is the wonderful people. I spend all day with fabulous coworkers and chose to spend my free time with a different group of Microsoft employees. I cannot say enough about the professional support, as well as the personal contacts I've found within Microsoft.

Cons: Cloudy vision for some areas. Satya Nadella seems to have a cohesive vision for a unified Microsoft. There will be some growing pains, but well worth it.
