That's not uncommon, assuming that an initial phone screen counts as an interview.

I have had stretches where it took me talking to ~80 candidates between initial phone screens, random chats, etc over two months before finding someone to hire.

And to be clear, I am not claiming that I found the 'best' person out of 80 people. 'Best' is a very custom definition depending on the environment, role, and fit.
