Tactical TeleSolutions Interview Questions and Answers

Round: Test
Experience: Normal typing test and some aptitude question

Round: Resume Shortlist
Experience: For CSE and EE students , CPI was not at all seem to be a criteria for shortlisting and almost all who have a decent profile got shortlisted for the test. However, for other department students they shortlisted above 9 CPI students.

Round: Test
Experience: It was a 2 hour test. It consisted of 3 sections-Quant , Machine Learning and Computer Science . Each section had 10 questions and 45 minutes were allotted for each section.
Being from non-CSE background I attempted only 2 sections ie. Quant and Machine Learning. Machine Learning section was fairly easy this time and almost all questions were standard. If someone has done an introductory course on Machine Learning and basic stats , this section was a cake walk for him. However , attempting quant section required some preparation of solving probability puzzles (computing expectations etc.) ,basic linear algebra and geometry base questions.
Duration: 2 hours

Round: Technical Interview
Experience: I had 2 rounds of interview. Both were technical ones.
In the first interview , they asked some probability puzzles (from 50 challenging problems in probability book) . Since I had completed that book before , I was able to solve them . Then they asked 1-2 algorithm based questions like formulate an efficient algorithm for solving a particular problem. I was not able to solve them completely but tried to give them the overview of y approach. The interviewer didn't seem to be satisfied though. It lasted for around 20-25 minutes.He told me to wait outside . To my surprise, I was called for the 2nd round.
The second went better than the first round. They again asked questions on computing probability , expectations , constructing a Markov Chain for a a given problem etc. Since I had done 1 course in Fiance also , he asked me questions from it also which were quite easy. Then he began asking algorithms and asked me to explain a sorting algorithm and I chose Quick Sort. While explaining it , I got struck at one point but the interviewer was helping me by giving hints and I was able to explain it fully. The second round was quite exhaustive as it went on for around 45-60 minutes.

Round: Case Study Interview
Experience: I asked him about the product X? and how important it is for the telecom service providers? is it a big part of their costs ? – he said some arbit stuff – this was a hint that it was a bigger overall strategy case and not into details – so I defined the case as – the CEO wants to know, what to do to increase the profits both in short and long term – he said yes - I immediately moved to the standard profit loss framework and started looking at revenue first - he said OK – I said profit = Price* Quantity and went to pricing... he had said that the telecom service providers were not very sensitive to pricing in the business.. so I dint come to reducing the pricing... I asked about the competitive landscape – our client is 35% business... it went on and on an on ..... could not reach anywhere.. so we went to costs... discussed everything.. excess capacity.. joint ventures.. MnA,..still nothing..so he said.(the discussion was a very intelligent substance discussion.. not general profit loss cases.). – we had a great discussion on both prices and quantity,, why don’t u see decreasing the price – I said.. “ooooooo I thot of it, but then u said that the players are insensitive to price “ - he said “ they WERE, the whole industry as I told u is seeing some problems” – PICK UP THE HINTS... -- once he said this I went to the cost structure of the firm again – I said that our client can play price war only if a) his variable costs are lower than competitors variable costs and he is playing on high investment low variable cost model (reliance model) – he said YES it is exactly this way – I said OK , then let him price X above his variable cost but below the others variable costs and drive the competition away. – I also said, to speeden this up he should in fact price it lower than his variable costs also (extremely low and he can afford it because he has cash with him as he has been on 40% profits for the last 4 – 5 years.. so there should not be an issue on the working capital side – he sair “great” .. he wanted to stop and asked me to summarize the case.. – I summarized the case, and also gave some more ideas like .. seeing the cost and benefit of doing away with excess capacity rite now and adding again when the market is doing good, buying high fixed cost players in the sector.. etcc etc.. a lot more.. – he patiently listened to everything Then he asked me if I had anything to ask him? I asked similar question as I asked in Mck – “ has India become a net contributor to the knowledge base..- he told me about low cost Indian manufacturing.. I said cool... and he said super cool!

Round: Case Study Interview
Experience: Upfront questions – where in the value chain? – ans.. they make towers and maintain them .. and into providing services too.—so I asked details on the portfolio of services and portfolio of work of tower etc. – he gave me everything including margins.. so margins in tower making etc were low – I asked him if he is sure that its not just an accounting issue.—he appreciated the point and said .. no, they do ABC and might be small accounting issues but not really one—I said ok.. and moved on to profitability framework .. revenue – costs --- so I said we will look at the tower making etc.. (pareto) – he said perfect.. – went to revenue... he hinted therez nothing there , I said great! Jumped to costs (didn’t waste time at all) - asked him costs heads .. he gave the following .. – a) Tower making, b) people c) administration (I don’t remember the terminology correctly but the remember the discussion) Discussion on tower making – I said “ so Navneet, what does it include” – he said making and servicing and maintaining and some back office work – so I said following can be wrong (BE CREATIVE, I started throwing solutions/ideas) (i) are the people skilled? Know how much material are they using (extra material = extra cost) (ii) is the quality of material too high (more than required quality increases the costs) (iii) is there rework happening? – are people good?(iv) What kind of designs are there – he said there are various different types of designs – I asked why? – he said no one knows – I said .. are they required? – he said , no – I said then standardize the design! He looked happy – so I started throwing more ! – he said no, lets move on to other ones Discussion on people – people cost = wage * numbera) are outsourced people expensive – yes they are – are they doing some specialized job? – not really, they can be replaced – then replace them b) can we multiskill people – yeah we can – then do that! c) Can we move our service centers to low cost destinations – yes we can d) Can we reallocate people to reduce number of people – yes we can – but can we fire them? – are they unionized? – yes they are and he appreciated the point that I touched upon the fact that the unions are tough to handle ( learning : know your industry, small things can make you win the case Discussion on administration a) planning happening ok? – no – so scheduling, audits have to be done again and again (I did not come up with this point alone. It was a result of a thorough discussion .

Round: Case Study Interview
Experience: i said – its an opportunity (no structure , we were taking a walk after all) because it opens up a full market – he said ‘ what shud the competitors do” – I kept on saying a lot of things... - they should lobby with government to stop this .. bla bla bla bla – the discussion was round and round and round.. I was tired with my high heels—then suddenly I said – Arvind can you tell me if I am on the right track ? , am little tired – he smiled and said, ok I again ask you “ what can they do to stop the nano or get ready for the market” – this statement gave me clarity and I said “ ok we can stop nano from coming, or do some other stuff” – he said great , so lets discuss both one by one – (remember that once you asked for clarity then you have to crack the rest of the case, else you are dead) –so I picked up stopping nano to hit the market discussion on stopping Nano to hit the market –
(i) demand side hit – lobby with the activists and say that the infrastructure isn’t ready and hence nano should not be allowed ( he liked it)
(ii) demand side hit -Increase the advertisements on how “Indians have to be sensitive about infrastructure” ( he liked it)
(iii) supply side hit – can we buy out the suppliers? – can we promise them some other meat? – like get them under long term agreements etc
(iv) Supply side hit – can we buy out the low cost suppliers to tatas ( I told them, that my thinking was to stop providing necessary materil that gets into nana
(v) Supply side – can we buy their engineers
(vi) And some more discussion, I don’t quite remember .but ya on similar lines What else they can do till they develop their own low cost (i) can they give fire to second hand car market ( as this is the immediate competition to nano) (ii) he kept on probing me on public transport till I said – why cant they collaborate with the government and make the public transport so easy and good and safe that people don’t need nano! BINGO.. ( he loved it- tho he only got that in my head – amazing guide he is) he still looked dissatisfied and asked me there is something else that is missing.. – something that is a real threat to the competitors of tatas. – we kept on discussing, till I suddenly remembered the team that made the engine is of 30 years average age (READ THE CURRENT ISSUES, IT HELPS BUILD PERSPECTIVE) – so I said “ they have the engineering skills, which can be used to enter other segments (like they can make cheaper engines for indigo .. or come up with new car in ford Ikon category etc).. and this resource is just too good! – BINGO

Round: Case Study Interview
Experience: After some general questions related to my profile, academic background, work-experience and interests they moved to cases.
1. Your client wants to establish a cement factory. How would you approach and what all factors would affect the location decision?
2.Your client has developed an eye solution, using which a customer can do without spectacles. However, one unit works only for one day. So, an user will have to consume fresh unit everyday for solving same problem. Assume that the cost of producing these units is negligible. The cost incurred so far is on Research and Development which is substantial amount. How should they market and price the products?
3. Estimate the market for second hand cars in India?
4. Moser bear has launched DVD range at affordable prices of Rs. 30-40. a MUSIC COMPANY, x has been in the market for last few years and has been selling DVD's for Rs. 250-300. How should they react to the situation of continuously falling demand?

Round: Case Study Interview
Experience: Case: A manufacturing Co. produces three products: A,B and c cost of production of each is Rs 20. The SP of A= Rs60, B=Rs 80 and C= Rs100. The company produces the same amount of all the three products. In order to earn more profits, the CEO of the company feels that the company should concentrate on producing C, while the CA says that they should go for product A. The CEO a friend of yours comes to you for consultation. Can you help him out?
Profit per unit is ficed; hence the number of units is the variable part.
Thus the important factor is the time required for the production of each unit of product A, B and c. In this case, the interviewer told me that the time of production for C is 1 hr while for A its 15 min and for B 30 min. Thus, the profit from A will be larger compared to B and c.
Other options explored :
- The market growth rate of the products
-The taxes on individual products, in case there are any(because of the CA factor)
-Competitors for the given products.
Tips: As with me, many people, or at least some, tend to give importance to a particular thing on which the interviewer would have stressed on. While this may be so, but its also possible that he's trying to mislead you or give you a broader option. I believe the appropriate approach would be to take a two way approach which in this case would have been an accounting approach and other an operational approach.

Round: Case Study Interview
Experience: Case1: There is XYZ refrigerator manufacturing co. The company has only one factory in the centre of the country. From there, it distributes its products throughout the country and hence incurs some transportation costs. There is a competitor situated only about a km away. The management of the company comes to know that the transportation costs of the competitor are considerably less than theirs. In order to find out the reason they have hired you. so How will you go about it?

Analysis: The total transportation costs of the company will depend on three factors.
These include:
- distance travelled per trip
- costs per km of distance
-no. of trips

Since the competitor was also located in the same area, the distance traveled per trip and the cost of trip per Km would have been same. This gets us to the point of no.of trips. It might have been possible that the XYZ company might not be fully utilizing the capacity of the truck and hence required more number of trips to transport the same number of refrigerators as the competitors. Thus, they should be concentrating at maximum utilization of the capacity.

Case 2- Estimation
You are the head of ESPN-STAR. Formula 1 is coming to India and you aim at bidding for the television rights of the same. How would you go about doing it?

The estimation can be fairly carried out by structuring the population in 2 ways:
-one the basis of cities: Divide into urban cities, satellite towns and villages
-on the basis of age: Divide into 3 groups 0-15, 15-20 and above 50

For each city based on population divide it into the three age groups. Now in cities, people in the age group 15-50 are most likely to watch formula 1. let the number be 30% of them. For below and above this age group, let the number be 10%.
In case of satellite towns, the percentage of people in 15-50 age group can be assumed to be 15% and 2-3% for people above and below this age group.
while in villages it can be safely assumed that nobody watches F1. Thus estimation can be carried out in this way.


Tips: being a fresher and not being used to interacting with high profile people was at the back of my mind. Hence, I had a very cautious approach to my interview and probably hampered my natural thinking and flow. So for probable interviewees who feel the same , it is advisable to be as natural as possible.

General Tips: Be as natural as possible
Structure the case properly.
Aim for a good interaction by asking them questions.

Round: Case Study Interview
Experience: Case:A cement manufacturer based out of East India has been seeing his prices in east India dip heavily in the past few months. Despite being the market leader, he seems to be unable to arrest the fall in prices. The aim as a consultant lies to raise the prices by 10% and find a strategy to make sure the prices do not fall so easily again.
Case analysis:
This was a very complex case with multiple problems and solutions with each having a different set of pros and cons. He wanted me to see the case from a simple
demand and supply point of view.
Structure:
The supply was overshooting demand in the market as a result of the actions of competitors. So the issue was also to do with the distributors in the middle and how brand consciousness would come into the scene. The structure could be simplified to a 2*2 matrix with price elasticity of demand and brand consciousness on the axes. The issue could be then simplified on the basis of the quadrant in focus.
Summary:

Overall, the issue was embedded in being able to use game theory with the distributor and play prices up and down at regular intervals. Another strategy was to enter into forward contracts.



Round: Case Study Interview
Experience: The interviewer was very calm and reassuring and that helped me build the conversation.
Case: A local taxi driver in Delhi wants to explore the possibility of signing a contract with a radio taxi service. Help him with his dilemma.
Analysis: This was a case that really tested your ability to think far and wide because the math was simple but the underlying logic could have been missed very easily.
Structure:
Used a simple revenue-cost structure for the pre and post radio taxi phase. Then tried to see if any of the key variables could be modified to come up with a different result.
Summary:
The case had two parts- one was the initial decision and the decision after changing a key variable.

Round: Case Study Interview
Experience: The interview took off with a general discussion on football and tennis and we spoke about our favorite stars from each of them. More than anything else, this was an amazing conversation where I could speak without any fears and inhibitions.
Case: A life insurance company in Sri Lanka is losing out on market share. Where does the problem lie?
Analysis:
The case was a test of structure to see if you could create one with all the levers enlisted.
Structure:
The market share could be seen as a function of number of policies sold and the revenue per policy. The discussion would then carry on the aspect of number of policies. The number of policies itself would be a function of a number of factors, out of which one of them was creating an issue.
Summary:
The toxic area was something to do with the insurance policy salesman and the entire structure had to be panned out so as to get to that

Tips: Be calm, logical and energetic. That is all you need to impress the interviewer.

General Tips: Be energetic.
Calmness and common sense are the key.

Round: Resume Shortlist
Experience: McKinsey looks for a spike in your resume, people who have commendable achievements is their field of choice, academics, extra curriculars or sports. So be sure to make your resume accordingly. McKinsey adds a lot of weight-age to formal awards, scholarships, achievements (like inter-IIT) etc. But if you don?t have them (like me) you just have to make extra effort to show that you have equivalent achievements.

Round: Technical + HR Interview
Experience: First I was asked about myself and mostly my connection to dance and the dance club. (Some interviewers do this to make you comfortable at the same time analyzing your personality). In the first interview I was given an estimation case about the dish TV industry. Here the interviewer was mostly interested in my approach to solving the problem and if applicable my numerical skills. The second interview was a pure business case about the printing business. Here my creativity and business sense (read common sense as applicable to a business situation) was put to test.
Tips: Take on every interview as if that job doesn?t mean anything to you.
