Interview Preparation Tips

Round: HR Interview
Experience: The usual PI questions, I’d say be prepared with a list of them. The PI would give you on opportunity to strike the right vibes with the interviewer. So when you get down to doing a case, you’ll feel a lot more comfortable and confident.

Round: Case Study Interview
Experience: I asked a few clarifying questions. The information that I got was as follows – 1. The trend was temporary, and the market was expected to start growing again after a few years. 2. Need not worry about what widgets are; just consider them to be a part of machine equipment. 3. The manufacturer is a global company headquartered in US 4. The market had been growing over the last 2-3 years at 30 – 40 % and has now flattened. I then defined the problem statement. From here on I took a pretty unconventional first principles approach in structuring my though process. I decided to look at 2 aspects – a. Means to enhance Capacity Utilization through an understanding of the business based on b. Market Analysis Under capacity utilization I had intended to focus on Altering the product mix, increase sales geographically, rationalize my asset base, and providing value added services. The first one wasn’t possible and on the geographical front we were already selling globally. Then I switched to market analysis where I looked at # of players, respective market shares, competitive landscape, drivers of purchase and price points. On questioning, it turned out that we were the largest player with a 35% market share, two other major players had a 20% share each, and the rest of the market was fragmented amongst small players. Everyone sold at the same price. In past, the purchase decision had not been based on price, but on being highest in quality, and we were perceived to be amongst the highest in quality. We were also the cost leaders in this business, and this was the catch point. It also turned out that in being more cautious about their purchase of widgets, our potential customers had now become more price conscious, and the market was price elastic. From here on I started shaping recommendations – I put them as short term and long term. In the short term I suggested that we play on price points. Since we are the cost leaders and the market was price elastic, we can bring down our prices till a point where our profits increase with decrease in prices. Also, our competitors won’t be able to cut prices to the extent that we can, and in this way we can squeeze their margins beyond tolerable limits, force them to exit, and thus increase our share of the pie. In the long run, we needed to work around rationalizing our asset base, and building a value added service layer to our business. That’s where the case concluded.
Tips: I’d suggest that encase you too reach your solution pretty soon in the interview, spend some time to look at other strategic aspects, at points in your structure that might have been left untouched, but don’t panic if there’s nothing more to add from your end. You can close the case as and when you feel you’ve done what you wanted to, and need not wait to have spent a pre-decided amount of time on it. Yes I made it to the next round.

Round: Case Study Interview
Experience: I asked a few clarifying questions. The information I got was a follows – 1. The client was a $10 billion + company with 50000 + employees. 2. It was a Europe based company with operations all over the world, and their business was expected to grow at 10 – 15 % 3. The lines of business were divided into 2: A. Selling Equipment and S/W in 2G and 3G space. B. Providing Services, which was further subdivided into 4 categories.(i) Turnkey i.e. developing new networks (ii) Managed Services i.e. run the network on behalf of the service provider (iii) Maintenance (H/W and S/W) (iv) Consulting Solutions then defined the problem statement. From here on I structured by approach to do a Revenues & Cost analysis after having done a thorough Market Analysis. Under Market Analysis, I looked at 1. No. of Players – there were 6 -7 players, we were no. 2 with a mkt. share of 20%. The mkt. leader had a 30% share. 2. I looked at Growth in each of the businesses, Selling Equipment and S/W in 2G and 3G space each growing at 15 % and 25% respectively and overall this line of business was growing at 20% In Providing Services, the above 4 were expected to grow at 0%, less than 10%, 15% and less than 10% respectively (in the order mentioned above). 3. The drivers of purchase were driven by Cap Ex and Op Ex incurred by the customers, i.e. Price was the key driver of purchase once you were a part of the consideration set. However, to be considered for a contract by a potential customer, high standards of quality were a must. Before starting to look at the revenues and costs in trying to address profitability, I asked for the revenue break up of for our client. It was as follows – 55% from 2G(30%) & 3G(25%). 24% from turnkey. 9% from maintenance. 6% from managed services and the rest from consulting. I then asked for how this picture would look 3-4 years from now. Selling Equipment and S/W in 2G and 3G space would together constitute 40%, with 70% of this 40 from 3G and rest from 2G. Services would constitute 60% of the revenues, and in comparing to their current contributions, Turnkey would stagnate, Maintenance business would grow at 10 – 15%, and Consulting and Managed Services would grow disproportionately. This unfortunately is all that I remember of the case in terms of data, but from here on it was pretty standard. I prioritized my probing of the cost structures for each of the businesses based on their current and future contributions to the revenue pie. I then explored the cost structures for each line of business, identified the cost levers, and further prioritized my recommendations for each cost lever on the basis of where we could achieve most impact. On the revenue side, my recommendations were around building capabilities around consulting and managed services based on how the business was expected to shape up in the future. There was a lot to talk about under each of the above – off shoring, consolidation of suppliers and subcontractors etc., managing over runs, acquisition to build capabilities, and I did touch upon all of these. I'm sure based on your own judgement, you can add more to it. All the best!

Round: Case Study Interview
Experience: I asked a few clarifying questions. The information I got was a follows – 1. The client manufactured broadly two kinds of products A. Textiles (of different counts, pure yarns, viscose mix etc.) B. Garments (semi formal / informal in cotton, for both men and women) I structured my approach as follows: As part of Market Entry evaluation, I wanted to look at the following: 1. Market Attractiveness – size of the mkt., growth expected, penetration levels and margins. 2. Competition – in each of the segments. Further look at unbranded retailing, branded retailing and pvt. label retailing. 3. Strategic Fit and Capabilities as far as this proposed line of business was concerned. 4. How to enter – Organic v/s Inorganic At this point, I was asked to move onto the branding strategy that I would recommend. One key factor that I considered was a single brand v/s a multi brand strategy. And through discussions with the interviewer, I decided to pursue a multi-brand approach for different segments, different qualities etc. (just as Arvind Mills, Madura Garments etc. do). I then proposed that in developing a brand strategy for each of the brands I chose to pursue, I would look at the following: 1. Position the brand 2. Pricing 3. Distribution 4. Promotion. In positioning the brand (each of the brands that we will roll out), I would look at drivers of purchase and then position myself accordingly through parity and distinction. At this point, we got into a more general conversation around how to position, what other factors to consider, and then wrapped up the case.
Tips: As you step in for the interview, make sure that you leave all the excess baggage outside. It’s a big deterrent in one’s performance. I had one more interview that I’m unable to document, after which I was made an offer.
