Q: There are a couple of reliance stores that are bleeding(doing really bad) in one region. You have all the necessary data related to these stores. What would be those factors that you will consider first ? What will you do to ensure these stores do well.
Since I had retail background it was easier for me to understand the scenario based question. The interviewer wanted to understand how I would approach the problem.
Last, I had few questions to the interviewer based on the role.
On the same day I received call from HR saying that I have cleared the interview and offered the role.

This round is the most tricky one and you really need to be very careful in what you answer in this interview.
Interview Preparation Tips
Tip 1 : Extensively practice on SQL, SQL queries, extracting data, different types of joins as I had to solve and extract specified data from a dataset in front of the interviewer during the interview. Also, there is a telephonic pre-interview round that is focussed on SQL and Statistics basics. You need to clear that to move to the interviews.
Tip 2 : Practice lots of guesstimates, puzzles, problem solving and Case studies. Guesstimates may include questions like estimating the total area under warehouses in a specific region (I was asked something similar to this).
Tip 3 : Extensively read about the company, JD and the core values of the company. They seem to focus extensively on these values and you need to prove that you fit within them.
Tip 4 : Be really cool, confident and you need to know even the tiniest details of your project work. Grinding on projects and tech skills are a part of all interview rounds.
Tip 1 : Clean and Concise, only put things that you are very much comfortable in answering even to the tiniest details.
Tip 2 : Heavy focus on technical Skills. Mention the exact tech skills and project work/tech you used on those projects because they really pay attention to every nook and corner of your resume. Include you extra-curriculars as this is extremely important during the interview process. They will ask you to mention/describe situations where you showcased a particular skill (for hints related to these, refer to the core values section of their website.)
