After MSFT bought GitHub the most pleasantly surprising thing to me was that the MSFT ICs that came over were… very good. Those I worked with were very technical, able to have technical discussions, and took feedback very well. I loved working with them. By then for years I already had long struggled with lots of product teams at GitHub. Many didn’t care for code quality, accessibility, nor performance. Not the MSFT folks. They also felt correctly leveled, no fluff in leveling.
