Six months as a 'senior' and I still Google things I said in the interview I already knew

Got the title bump, the pay bump, the whole thing. Still catch myself opening a private tab to double check something I explained confidently to a panel six months ago. Nobody warned me the title changes before the certainty does. Mentioned it to another senior on my team half-joking and she said she's been doing the same thing for four years. Somehow that helped more than any promotion did.
