It's just my first month and my manager said I had to improve a lot because his expectations for a senior engineer is much higher, not just technically but also behaviourally.
I'm feeling anxious because I was in a pretty laid back company before and the rapid pace of a startup took me off-guard. I'm trying to push through by working longer hours but I don't think I'd be able to reach my manager's expectations.
It's causing me anxiety just by thinking about my job. Is it ok to leave a job even if I don't have anything lined up yet? I'm trying to review to get a new job but the long hours are taking up my personal time. What could be my options?
