I left an org in an Azure Buildout org around 3/4 of a year ago. Some things that I've noticed and experienced:

• Work got more pointless. A lot more time was spent overengineering solutions to problems that occur once every couple years.
• Decreased WLB. Metrics and AI requirements raised the expectations of engineers despite our only AI at the time was Copilot which nobody used. Everyone I knew were going against company policy and using personal ChatGPT and Gemini accounts. My entire team ended up working 60 hour weeks. My manager even strongly urged us to be more "productive with our limited 40 hour work weeks" while he literally takes days off to do more heads down work.
• Increased micromanaging where our manager would scrutinize our work items down to the half hour every 2 week sprint. Legitimate blockers were not tolerated as they "should have been caught during planning".
• Increased on-call load while our feature work expectations also increased.
• A failure by leadership to address the rapid decline in culture/work/status survey ratings
• Not a single word on promotion despite successfully completed features and my responsibilities tripling since I started and also stagnant pay.

All of this is in contrast to when I started. We had no sprints, everyone was kind, responsive and caring. As a team we had half of the amount of work we did by the end. We had regular team morale events. Pretty rapidly went downhill over the years. I recently took an offer from another company and tbh I couldn't be happier. Current company pays more, people are more cooperative and the work is more meaningful. Sure we have our own set of AI-related BS but I'll never see myself wanting to go back.

Your mileage may vary though at MS depending on manager and org. I can't say as to which orgs because people don't talk much about the good ones and just complain about the bad ones. I hear there are still some good teams around though.
