These are examples of what a human services interviewer might ask. I’m not saying that these are definite questions, but I am going to say they will be similar to the ones I listed. For example it could be something like:
Why do you want to work at this particular agency?
When was a time when you were not able to give a customer what they requested, and how did you handle the situation?
Tell me a time you made a mistake, and what did you learn from your mistake?
What type of experience do you have working with the public?
What makes a successful supervisor?
Are you comfortable giving presentations?
I hope this helps you out! Please let me know. : )
