NHS Adminstrator interview questions

I arrive and get taken to a room where two interview panels are waiting a co-coordinator and a senior manager.I have been to be a few interviews for similar roles at the NHS and always find you have one member of the panel that tries to makes you feel comfortable and easy and makes an effort to make the interview process pleasant and the other panel member has a face on and shows no effort, no response to any answers you give to her questions,a little smile goes along way especially if you are a shy person and get nervous at interviews.Usually last 20 minutes.
