Golden rules: ask open questions and let the candidate do 70% of the talking. Open questions are ones where the answer is not just yes or no. So rather than saying �can you type?� say �what experience do you have of typing?�.
You might think about things like:
What experience do you have of working in a small office environment?
What make you think you�d like to work here?
Tell me about your experience of working with Word/Excel/Powerpoint etc. What are you most proud of being able to create in these packages?
Tell me about a time when you�ve dealt with a difficult caller?
Give me an example of how you�ve worked with members of a team to achieve something that looked impossible.
And remember to ask if they have questions!
The usual format I would use is:
Welcome
Say a bit about the company, what the job is and give a brief overview (no more than 5 mins)
Ask candidate questions as above (20-30 mins)
Ask candidate if they have questions
Close giving clear indication of what happens next, timescales etc
Hope this helps
