The first round is at their office(in Ottawa). It is both behavioral and technical questions but mostly technical. They only asked 3 4 general behavioral questions. As for the technical ones, make sure you know methodologies, entity diagram relationships etc. Also, they make you write an formal e-mail, to see how you are in formal writing. The scenario is sending an e-mail to colleagues at Deloitte, explaining who you are etc.The first interview took about an hour all at once, with 2 people. As for the second and final round, which is also in their office, you interview 2 people separately, each half an hour interview. Very behavioral to see if you are a good fit. Also expect tough questions about your transcript. They let you know the result of the interviews within 2 weeks.
