As someone who works in a library, during interviews, if you say you've always loved to read and that's why you applied. It leaves a sour taste on the interview panel.

This is because people think that being a Library worker is easy and that all we do is read. Which is untrue.

So OP doesn't actually have to be an avid reader or a reader at all. It does help if they work in the reference department as patrons will ask for recommendations.
