While I was out directing 50 HS/MS on how to act on the Ed Sullivan Show, someone asked me online what questions I'd ask someone interviewing for a youth and family position. Here is a short list of things:
Why do you feel this ministry is important to a church?
What things would be a sign to you that a church thought this ministry was important?
In doing this ministry, what things do you see being the best use of your time and skills?
What are some of the best things you've seen others do that you have not been able to replicate (and follow up with "Why" if needed)?
How do you see other ministries in this church affecting and intersecting with this ministry?
Where do you feel you (would) work best when doing this ministry?
In what ways do you find the parts of this ministry similar? different? (depending on what info they have may also have to ask "what do you find to be the essentials of this ministry")
Something you thought would work really well didn't turn out the way you expected, what would you do?
How do see relationships, programing, resourcing, and planning working together in your view of this ministry?
A new family comes to worship, what do you do? (or has been coming for a month, depending on what you want to know)
How does your own life reflect the ideals that you feel are most important to the work of this ministry, in what ways does it not?
How does this ministry affect other groups in the church (list if needed)?
How do you deal with someone who feels that a major part of your ministry is "not for them?"
Who are the most important people to your ministry?
I could go on for a while (and have) but this is a good kickoff interview list I think to get people to possibly give more than just canned answers and open up comfortably about if a ministry is truly a fit.
