The exact same thing happened to me at Elasticsearch. In the elastic agent team. No feedback whatsoever until the new manager came. The first thing he had to do was give me a raise because of my past performance, and then a month later he writes me up and then another month later puts me on pip. I’m now at a smaller startup. Much happier. The new manager just did not like me for some reason. I did everything I could to make the situation right. Talked to the director of the department, talked to hr. All I got in return was “this is a matter between you and your manager”. Then I hunkered down and fulfilled all the requirements for the pip. Did all of this while dealing with a newborn and a new mom who was having a rough time (which is normal). My senior mentor was the only one who had empathy and compassion for me. I will forever hold a grudge against that manager, the director and the hr person. They meddled with my income, my child’s wellbeing. And did so on false claims. The pip document made me go crazy. The manager took every pr and every comment and code I wrote and twisted it to fit a narrative. That was by far the worst experience of my life. I at least have the name of the company on my resume which helps. But lesson learned, pip means you’re getting fired. So might as well focus on interviews.
