Interview Preparation Tips
Experience: Though the paper was easy you have to score very high marks to qualify for the next round.
Duration: 30 minutes
Total Questions: 25
Round: Group Discussion
Experience: The GD round consisted of current affair topics. Since topics like these are very popular and everybody likes to talk about them, it is important that you start the topic so as to have a good hold over the group. If not just try and give a direction to the group with valid points so as to become noticeable. Do conclude the discussion.
Round: Interview
Experience: The interview was basically resume based. They asked me about my projects in the domain of finance and were quite impressed by it. They wanted me to discuss all my academic and internship projects in detail. The interview lasted for 30 minutes approximately.They also inquired briefly about me. They also asked me questions about my technical projects though it didn't have anything to do with the profile offered. Their main aim was to know whether I performed well in the tasks assigned to me even if they did not interest me.
Tips: Try not to mention anything about MBA if any one of you is planning to go for it.
