Interview Preparation Tips
Experience: The interview started with a detailed discussion on various fascets of points on my CV. Neeraj wanted to know about my thought process as I went through the various phases of my life and how I took decisions that I actually took. For example, he was very interested in knowing as to why I chose IIT Bombay for my B.Tech when I could have gone to join IIT-Delhi which was nearer home. The idea was to develop a rapport with the interviewer by being clear, insightful and interesting in your answers. Be very nicely prepared with your CV and think through the various decisions you have taken in life, keep smiling throughout the interview, present a firm hand shake, think before you speak and engage the interviewer in a discussion.
Round: Case Study Interview
Experience: I started off by trying to understand the situation as clearly as possible. The one dictum I stuck to in this and other case interviews was to really get to the crux of the matter and scope down the problem relentlessly to what the top of the line issues were for the client. So trying to be MECE, I told Neeraj that I would look at the following three alternatives: - Not do any thing about the excess capacity and wait for the good times to come back- - Downgrade the capacity by eliminating excess - Find better uses of capacity or sell more to existing customers A free flowing discussion followed on each of the points above and Neeraj very quickly refuted the first two suggestions. We then dived headlong into the third suggestion and it quickly appeared clear that fiber optic cables were commoditized products to a large extent. I asked Neeraj about the specific ways in which we were better than the competition and got to know that our client had better product quality at the same price. I drew a perceptual map of our Vs. the competitors’ positions on these maps and argued that we may want to play upon our better product quality to induce the customers to buy more from us. When prodded further by Neeraj, I used the tried and tested Raju formula: Market Share = (Share of Voice)X(%of acceptability)X(%of availability) Since availability was not an issue and since advertising was not a main concern, he asked me to dive into ways of improving our Client’s share of acceptability. I proposed pricing as a way of doing so. I postulated that we needed to study our client’s fixed costs and those of our competitors’. Based on the fact that our fixed costs were lower than those of our competitors, I argued that we could play the pricing game by bringing our prices down and cornering a bigger share of the market. I further argued that if our competitors tried to imitate us in this price war, they may end up chasing us to the bottom of the barrel and get killed in the process. This would only be good for the industry which badly needs consolidation given the excess capacity. I think Neeraj was visibly impressed by this time by the depth of analysis I had presented and the diverse ideas from marketing, managerial accounting etc that I was able to bring to the table.
Tips: Be yourself.
Be confident.

- Q2. What is hoisting in javascript?
- Ans.
Hoisting in JavaScript is the behavior where variable and function declarations are moved to the top of their containing scope during the compilation phase.
Variable declarations are hoisted to the top of their scope, but not their assignments.
Function declarations are fully hoisted, meaning they can be called before they are declared.
Hoisting can lead to unexpected behavior if not understood properly.
