Moved from frontend to backend on the same team and the imposter feeling came back harder than when I was new

Three years of React. Reasonably confident, people came to me with questions. Got asked to move to the services side because we were short-handed and I said yes straight away.

Six weeks in I'm asking things I'd have been embarrassed to ask as a junior, except now everyone knows me as the experienced one. That gap is the uncomfortable part. Not the not-knowing, the being-known-and-not-knowing.

My lead reckons it takes about a quarter to feel normal again. Holding onto that.
