Spokane County Library District interview questions

I applied and was contacted for an interview about a week later and scheduled my interview for a week after that. The interviewers were nice enough, however there were two of them and they wrote a lot of notes on their papers and asked many situational questions. It made me a little nervous so some of my answers came out shaky. For the position I was applying for I had to also read them a children's book and explain why I chose the one I did. If I have any tips it would be don't disclose your exact availability until you are hired.
