Interview consisted of a 1-2 page essay, a 60 point questionaire. After you are done with that you go on to the oral assessment lasting about 2-3 hours. Interviewers were friendly and made it comfortable yet formal. Many of the interview questions required alot of though and they are designed to assess your capability to problem solve, communicate in an effective manner and how knowledgeable you are in your field. Fairly pleasant experience.
