UNICEF Data Base Administrator interview questions

I had two interviews. At first I was greeted by three employees (I later learned that one of them will be my supervisor, the other two are also in high positions in the office). I should say something about myself, I said which schools have I finished. They asked me how I handle knowledge in Excell. They asked me some specific questions from Excel and they asked me if I would be able (for a long time) to do this job, because it's quite exhausting and uniform. At the second interview, I had a conversation with someone who is right next to the boss's office. She told me what is my intended salary, warned me that my contributions will not be paid, as well as transportation. They were all very polite, and I can not at any time feel uncomfortable.
