So I’m not sure if I am overthinking things. However, I recently went to an assessment day for a dream job. I got a lovely phone call from recruitment a few days after saying they really liked me, and so I’m one of few to be asked for the next stage interview (another stage after that too)... I was professional and polite, then out slipped out of my mouth “awh that’s made my day, thank you”

Will this be seen as unprofessional?
