The only challenge was managing the time limit and maintaining accuracy. One could not review the questions already answered and cannot move to the next question before attempting the current question.
It was a JAM round, nothing like GD. A group of 10 students was judged by a panel member. Student had to choose a number of his choice from 1 to 40 and the corresponding topic was alloted. He/she was given a chance to change the topic if uncomfortable. 30 seconds to think on the topic and 1 minute to talk over it. Every student got a new topic after one student had finished. Some panel members questioned the students on their topics too.
Topics were related to technology, social media, internet and general ones. Eg : Smart watches, 3D printing, self-learning vs classroom learning, internet access to various sites, automation, etc.
It was an interview round (one-on-one). 1st question was : Tell me something about yourself and Why Deloitte?
The answer determined the nature of the further interview. Some students were asked only about their extra-curricular activities and no technical questions, while some were questioned based on their resumes, and some were asked technical questions.
I was asked what I knew of IT sector, why I had applied for a non-core IT company, what programming languages I knew, what according to me was my role in the company if I join, any projects I had worked on related to IT, and a small code relevant to my project in C++.
