Expicient Associate Consultant interview questions

First round - Aptitude was nice. Second round - Spoke about my resume. The interviewers were very nice. Third round - It was fun (totally unexpected). They asked me to speak for about 20 minutes from a range of topics. The interviewers were very convincing that it was a good place to work. All seemed jovial and i think I would like to go work there.

There was a general aptitude test which had moderately difficult questions. The next round was an interview where very few questions related to favourite subjects/branch of study were asked. interview was mostly non-technical/HR. Final round was an extempore round where candidate was asked to speak about a topic of choice for 5 minutes and then was asked extensive questions on the same.
