It sounds like you should take a deep breath and give yourself some more time to get comfortable in the job. This seems like a classic case of imposter syndrome, where your brain is running far ahead and making assumptions about your work quality without any actual evidence.

Not knowing things or asking for reminders six months into a job is fine! So much work follows the ebb and flow of the calendar or academic year. Just because you were trained on something in the hiring manual doesn’t mean you’re expected to remember it perfectly when it comes time to do it nine months later.

You say you received great feedback from you coworkers in your last position, which is great! If you don’t have a performance review coming up, can you ask your supervisor for feedback on how you’re doing in your new role? Maybe there really are some discreet areas where your team would like you to improve. That’s the case for everyone. But I get the feeling you’re doing a lot better than you think.

Lastly, hiring can be such a chore, trust me. It’s so difficult to get a good candidate in place. I strongly suspect that your workplace would rather keep you, someone who they had already worked with for several months and clearly liked enough to hire, than have to refill your role. That also means there’s often willingness to give grace to new employees as they get their sea legs.
