Interview Preparation Tips
Experience: I had a standard resume for this company as per our institute placement cell norms.
They were least interested in my resume. They cared more about your analytical skills rather than on your on campus activities.
Round: Test
Experience: The first round was the written test which had a few questions from data interpretation and some questions that were quite peculiar to the consulting sector as such. Only 24 students got shortlisted for the next round out of close to 350 applicants.
Tips: The cut off for the written test was very high. So ensuring accuracy and attempting all the questions is important.
Round: Case Study Interview
Experience: The next round was the case study round. The case that I was presented with was to calculate the number of hoardings in a metropolitan city with the help of given data. I failed to qualify beyond this round.
Tips: One should prepare for “Guesstimate” type case interviews (where the interviewee is tried to estimate the final answer based on logical deduction and analysis of the given facts) for this company as they give very high emphasis to the performance in the case study interview round.
College Name: IIT ROORKEE
Motivation: Indus Insight is a start-up which uses quantitative analytics to give solution to real life problems encountered in business. The company was founded by an IITB alumnus. It is growing at a fast pace and the best source of information about them was the pre placement talk organised by them.
