My first job out of college, I had a manager sit behind me for 8 hours a day with the ol' "move that one pixel to the left, no, 2 pixels to the right.. no back again" after I had impressed the customer with some fast results. I coped with it for a few days before telling him I needed to talk about his management style. He agreed, and we went out into the atrium. There, he told me I just needed to shut up and do what I was told. I think it's important to have an intuition for why you are being micromanaged. Sometimes it's because you're missing processes and procedures, sometimes it's because you intimidate your superior. I imagine the former should feel like it has an obvious expiration date, where you learn the CI/CD workflow or whatever. The latter feels sinister and crazy.
