They asked computer skill questions to determine my computer use skill level. They also asked several questions relating to analysis work. They asked me to provide examples of when I worked as part of a team and when I worked alone. How did I manage stress and what type of environment I like to work, and where I see myself in a couple of years and what my career aspirations are. The questions were not always easy but the HR contractor was very patient and gave me examples of situations so that I could think about the questions and answer them in the best way. The HR contractor made the interview process fun. When I left the interview I was not stressed at all which is unusual for me as I am a perfectionist.
