Interview Preparation Tips

Round: Test
Experience: I was really frustrated because of the rejection from previous companies and in the same time deeply determined to convert this one as this was the last company offering the profile of Business Analyst. I can say this based on my experience that converting a company is solely a matter of your preparation and self-confidence but a tad bit of luck is also a necessity.
Tips: I have been particularly lucky and so have been all the serious CAT aspirants in the online tests. It is not that you need to enroll in TIME with the word go, but rather analyzing your calculation speed, your communication and interpretation skills can do you wonders.
Duration: 60 minutes
Total Questions: 50

Round: Group Discussion
Experience: Obviously the topic was on Indo-Sino relations, which I was quite aware of. As this a topic on foreign policy, very few people were actually aware of this topic, so I had an obvious advantage. This is the most trite advice but still I will say this "Read, Read,Read".
Tips: There are always some people who are well informed of the given topic and some who are not and it is always helpful to be in the first group in GDs. I like to be up to date on current affairs and at the same time reading novels from the likes of Shashi Tharoor and my personal favorite Khaled Hosseini prepared me for group discussions. It is always helpful to proceed by looking @ the problem from different perspectives like legal, social, academic and technical or else if you are particularly unlucky you might face an abstract topic, where you might need to use your imagination, like one my friend faced "Yellow shoes with pink laces". Even now I cannot aptly describe this topic.

Skills: Communication Skills, Calculations, Verbal, Knowledge on current affairs
College Name: NIT BHOPAL
Motivation: My only motivation was the post the company was offering. As it will be helpful for future plans of working in an Investment Bank or pursuing an MBA.
Funny Moments: In the Interview round, they asked me why do you want join this company. In reply I started with the word 'Firstly' and said because of its profile and did not not think of the second reason and they asked this very thing. I took my moment and realized honesty is best possible way now and replied that you are last non-core company visiting this campus and if you guys reject me I might leave this campus unplaced (because of my weak technical background). On hearing this they started laughing and at that very moment I knew I might not after all.
