Pros
Access to latest technology. A lot of self development potential for either relationship, project or technical skills. Unlimited trainings for Microsoft products (if you are an FTE, not a contractor). Equity bonus and other benefits for healthcare, breakfast in the office. Great community and culture that promotes diversity.
Cons
Work life balance disregarded. Managers would not care what your days look like, how well prepared you are, they would just throw work and put pressure on you to finish it. Management changes too often (3-5 months change in leadership). Performance reviews are not fair, sometimes bonuses are halted because of one little thing that has no influence on the whole period reviewed, rather just a managerial decision. Mid and High management are very demanding and do a lot of micro-management. They also don`t take any opinions from employees, and put themselves on a pedestal with ease. Most management positions are given on friendship rather than competency and skill level assessment, and motivation most importantly to drive people to success.
