Deloitte Sr. Consultant interview questions

I initially applied online via an ad on Top Consultant that linked to the official website. After initial screening I was invited to an invitation only group session. This session was held in order to explain to all potential candidates the verticals and sub-dividions within deloitte and the work that they do. At this stage everyone was very professional and courteous - and I was suitably impressed, and could imagine myself working there. The next stage was supposed to be an assessment test - verbal + numeric .. and I performed well and was told that I would be carried on to the enxt stage. Its from this stage that I found communicating with the recruiters incredibly unprofessional. Most of the time they did not even have the courtesy of replying to emails even after more than a week. At one point randomly I get asked for a phone interview without any prior notice. - At this point the complete lack of interest and courtesy shown to me by Deloitte, completely put me off the whole recruitment process. And so I chose not to pursue this any further. I would like to work for an org that respects people and their time, and does not treat candidates like beggars.
