This was not a new job, but I got re-orged. There were a bunch of personnel changes and my manager's manager was also new in the role, but he was an old hand in the product we were building. The grand-manager controlled everything, and my manager did not have much say (at least in the beginning). 100% of our interaction was our 1:1s where he will either defer to his manager, or say "you are senior enough to manage this decision". Zero decision making.
Then one fine day he blew up at me saying "I did not do any work". He "watched my emails and slack conversations and did not get a feeling I was working". Long story here which I will omit. When we finished the meeting, which was in a conference room, I did not exit the conference room until I had reached out to a couple of teams who were hiring. I left shortly thereafter.
From the start, my boss at Company B was very dismissive, with very little interaction with me. Not because I didn't approached him or because distance (we sited one desk appart).
Then, despite a very positive interview with him, he quickly decided I wasn't a 'fit" and at the two-month mark, he let me go, citing my 'lack of Data Science expertise' as the reason. This happened even though the two major stakeholders, for whom I was doing 90% of the work, were super happy (as happy as you can be in two and a half months of work) with my performance.
The situation was frustrating. It was just two and a half months into the job (the first being holiday-heavy, with half the team out), and I was making progress. My role wasn’t to be a Data Scientist. I understand data, but my expertise lies elsewhere.
