As another former Googler, this was one of the most concerning things about my experience at Google. The pressure I put on myself and received from others when I was debating whether to leave was enormous, especially because it was my first job. Nevermind the rampant imposter syndrome while you still work there. In hindsight, it was super toxic and led me to stay there even longer than was good for me and burning out harder. I've talked to a few current Googlers and Xooglers who also felt that way.
