I have got an interview tomorrow at The Robert Jones and Agnes

I have got an interview tomorrow at The Robert Jones and Agnes Orthopedic hospital(spinal cord injury speciality) I was basically applying for all kind of posts without having much of detail in the NHS or trac profile due to lack of idea how to build it initially.

I only have 6months experience as medical officer as after internship I have got only 6months time before coming to UK for plab2. I am really in a fix for last many days how to proceed, currently doing attachment in medicine.

Could anyone suggest me regarding what post is it exactly! And what to answer if they ask why I want to get enrolled for the post !
