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.

College Name: NIT Delhi
Interview Preparation Tips
Experience: The questions were of medium to high difficulty. What set this test apart was the fact that each question had different weightage ranging from 0.5 to 3 marks per question. Time was a major factor. So my strategy was to attempt all the 1 and 1.5 marks questions which constitute the major chunk of the paper in around 40 minutes and spend the remaining 20 minutes for the 2 and 3 mark questions. I did not even bother reading the 0.5 mark questions. The 2 and 3 mark questions were difficult and those will differentiate you from others. 1600 students wrote the test and only 86 got shortlisted for the next round.
Duration: 60 minutes
Total Questions: 40
Round: Technical Interview
Experience: I was asked to write a C program to print the Fibonacci sequence and a basic SQL query. Apart from this I was asked a puzzle and other questions related to my resume. Out of the 86, only 26 students were called for the next round which again was a technical interview.
Round: Technical Interview
Experience: This was similar to the first technical interview. I had to write a C program to print the prime numbers between 1 and 100 and a puzzle was asked again. Apart from this a guesstimate to find the number of cars between 2 places was asked and a scenario based question too was asked. These were followed by resume related questions.
Round: HR Interview
Experience: All the 26 students who attended the second technical round were allowed to attend HR round as well. This was just for 4 - 5 minutes. I was asked about my family background and why I should be hired. My fondest memories from school days were asked too. Finally offer letter was given to 10 students out of the 1600 who wrote the test :P
General Tips: Just keep a calm head and attempt the questions. Ask for time to think if you are not able to answer the questions immediately. Be bold and confident. That is sufficient :)
Skills: Puzzle Solving Capability, Ability To Think, SQL, C Programming
