I had a recomendation, because I worked for KC before with very good results, so the interview was about explaining the job funtions. They also asked why I left them before, What were my professional and economics expectations, and how I would see myself in 5 and 10 years ahead.

Not too difficult. Interviewers want to get to know you but also they want you to answer the questions in the right method. I was interviewed in person which helped me to gauge the attitudes of the interviewers.
