SJAB interview questions

I foun an advert in the paper and decided to apply via post. Two weeks after I was called to an interview where they informed me of the position I was applying for. Then asked me about my background, previous jobs and my qualifications. The interview was around one hour and I had a good feeling about the interview. My advice is to stay true to the topics asked by the interviewer, and not to talk about things that has nothing to do with the job itself.
