I was first interviewed by 2 members of the staff. They had a long list of questions to ask me (why did you apply at Costello, why did you apply for the position). After that, they asked personal questions (last time you performed in a team and what did you do, last time you had to solve a team issue and how you faced it). After this section, I was interviewed by another member of the staff, who posed similar questions + the last question "why should we choose you and not other candidates'". All of them were very kind, and polite and made me feel comfortable. The overall interview lasted 1h15min.
