My skip-level at my first MAAAM job used to snipe at me when I was a new hire. He told me to my face he "would not have chosen me" and "didn't know how I got in." It made me so angry it was all I could do to hold my tongue until I got the fuck out of his office. But I went on to become very successful there, and he eventually had no choice politically but to support me. He got managed out a couple of years later.
