Two people runned the interview. First the presented the company and introduced themselves. A continuation I introduced myself talking about my education and work experience. They asked question about why I want to work on this position since my previous job was in a different field. After they made a big difficult question on programming using bits and memory allocation. It was not easy and with their help I could finish the problem. The most difficult part is to be aware of all the exception cases or NULL cases when you are on pressure.
