The test consisted of 3 sections.
Section-1 has Verbal ability questions and few passages ( easy though ). Section-2 was Quantitative aptitude where you have to be really fast. Section-3 was Logical reasoning
type questions. You cannot move to next question until you answer the current question.( there is no negative marking )

Its not Group discussion, but its a "JAM" round ( Just A Minute ), where you will have to choose a number and the topic corresponding to it will be yours.
You will be given 30 seconds to think and 60 seconds to speak on it. You will be doing this in a group ( consisting 11-14 members ),
one after the other, and the topics were mostly technology related, burning issues, etc..

The interview was both technical and HR.
There was only 1 panelist. She started with "Tell me about yourself?"
She had gone through my resume and questions were asked based on my resume and regarding my internships.
Then technical questions on Java, the basic questions on object, class, method,...
And then she shifted to HR type questions like :
Why are you willing to work in an IT firm?
Why Deloitte?
Where do you see yourself in 5 years?
And she ended with "Do you have any questions?"

Make a proper resume and ensure that you are well-versed with your internships and projects so that you could explain it well.
