A few weeks into my first dev job and I already feel like a hiring mistake.

Everyone around me just seems to know things. I ask what feel like dumb questions daily. Googled how to resolve a merge conflict yesterday and felt like a fraud doing it. Logically I know onboarding takes time. Emotionally I'm braced for someone to tap my shoulder and say it was all a mistake. How long did the onboarding fog last for you before things started clicking?
