McKinsey & Company Consultant Interview Questions, Process, and Tips

Interview preparation tips for other job seekers - research very well be authentic and curious during the process

Round: Resume Shortlist
Experience: a) I put a lot of thought into it. A LOT. I started top-down. In a sense, I always knew I was gonna target only 2 types of companies: Consulting and Banking. So made my 2 resumes accordingly. Basically I conveyed what needed to be conveyed. For this, I talked to a lot of people in Oct/Nov and researched a bit from previous editions of BePrepared. Being a DD helped. And then I spent a lot of time thinking how best to convey it. For example, I knew that my success in strategy competitions was crucial for Consulting Firms, hence I put those above my projects/extracurrics. b) Sent it to many people for feedback. Some of the points were accepted, some not. Its always our call in the end. But more often than not, external views make up the MOST important part of Resume Making. Advice: Make a rough copy first and then start thinking. If you think without it, it will take up a lot of time. DON’T LIE – IT WONT HELP YOU IN THE INTERVIEW. Be very serious in your resume. Avoid any kind of humor. Also don’t try to squeeze in too much.. you wont be coherent. Know what you want to convey and convey exactly that. At the end of it.. Look at your resume page by page. And see what it conveys at a VERY MACRO level. For ex: In my resume, Page 1 conveyed Decent Acads with Success in Strategy Competitions and Page 2 conveyed A lot of positions of responsibility with decent results and excellence in dramatics. I attended some of PPTs. Basically, from the beginning my focus was only on Consulting and Banking companies. In all I attended about 6 PPTs. But they do help. I know some of them are more than 90 minutes long. But its worth it in the end. There are some 5-6 important lines in every PPT and a wasted 90 minutes is worth those lines. Do catch the opportunity to talk to the presenters after the PPT informally. I found it to be quite valuable. Ofcourse, this meant less pizza consumed by me. But that’s okay.

Round: Interview
Experience: 2+ 2 rounds of interview after resume short-listing. Total 22, After 2 rounds: 6 Final Offer: 3 (out of which 2 accepted). My McK interviews were scheduled immediately after my 2 BCG interviews. So I was not tense going into them. Round 1: It started off with general HR. Which is how all interviews typically are. This is to make the interviewee comfortable. I was asked about my dramatics and my economics project. He was looking for short, precise answers. Then came the case: I was asked my sport of preference. I said Football. He asked me to Guesstimate (Guess + Estimate) the number of footballs in Europe. (For those of you who are not familiar with guesstimates: It basically involves coming to a number logically. You can either approach it from the supply side (involves estimating the total capacity and multiplying with a capacity utilization kind of a thing.) or the demand side (estimating the number of users and then multiplying by the frequency of use). I told him about how I can approach from the demand and the supply side. I said I would like to use the demand side as I thought it was easier. He asked me to instead use the supply side. This came as a shock as I had hardly practiced anything from the supply side (Lesson: Be prepared to think about novel problems – which you have never practiced). I made a hash of this one. I made a lot of mistakes. But the good thing was I was speaking aloud whatever was going inside my mind. So if I said: “costs at all London shops will be the same”, my interviewer would interject and ask “Would they”.. after thinking for a bit I would realize that they wont be since the transportation costs are different for different shops (unless they are competing) . I think he got impressed by my ability to recognize that I have made a mistake and the ability to rectify it. After this he asked me if I had any questions about McK. I had a few and asked him the same. .
Tips: Lesson Learnt: Don’t have any conceived notion of an interview. You can be asked anything. Go with an open mind. For Cases, Speak aloud. Don’t be stubborn on your findings. You could be wrong.

Round: Interview
Experience: Immediately after round 1, I was whisked away for the round 2. This was a senior partner. He grilled me about how my CPI was low (8.48) . He asked me whether I was against McKinsey taking up govt. studies. I said No and explained him the reason. He was happy. Quite literally. After that came the case: “A and B are the two top Cement manufacturers in India. A foreign cement behemoth C has bought both of them. C is now wondering how to integrate the HR of the two purchasing departments of A and B. What are the possible options? What should it do?” The case was 2-pronged. I had to identify the possible options first and then suggest one. An important learning was that I established the various “parameters” on the basis of which C must decide which one is the best first. I thought I did pretty well with this. The interviewer seemed very happy. After the 2 rounds, I was called by McK people for feedback. I was told that sometime I come across as too Assertive and that should be avoided. I found this feedback very helpful. And later on I realized that a consultant is typically a quiet, analytical, serious character and not a bubbly, flamboyant one.
Tips: Lesson Learnt: Don’t be overtly aggressive against some of the firm policies (govt. work in this case)

Round: Interview
Experience: It Was with a partner, again. I was told in this interview that my temperament and way of speaking was to b observed. He asked if I wanted some tea since I looked tired. I said yes. He jumped straight to the case. “A boiler co. wants to go global. Advice.” I didn't have much information about the boiler industry and hence clarified a few doubts. Every second I nagged myself to be less assertive and be more open and unbiased to information. He didn't let me solve it completely. Stopped in between and said I did okay. Ambiguous statements, very typical of consultants. :)
Tips: Lesson Learnt: Respect the client (in this case the interviewer). He knows much much more than you do.

Round: Interview
Experience: Was with a German partner. As I entered the room he said how everyone is very keen on me.. but then said he was not sure and had to see for himself. There was no case in this interview. It was mostly fit. We talked about cars and football. I have never had so much fun in an interview. It was awesome. In the end we agreed that Germany played some kick ass football in the world cup and deserved to at-least reach the final. I was told in the interview that I would be made an offer.
Tips: There are no ready-made formula. However, to get shortlisted he/she must have spikes in his/her resume/CV. The person should be hyper-analytic, open to ambiguity, a person who never gives up and above all should be able to communicate well. You need to also present yourself very professionally in front of this company. It tolerates no informality. Know why you want McKinsey/Consulting etc. Prepare case-studies well. Don’t over-prepare. And you definitely need some luck. Looking back, you realize its only one or two statements that you make which makes you unique.

General Tips: I think the biggest learning was the fact that each company has a different work culture. You should do some research on this also before. I hadn't done much research on UBS and it showed. You will also need to prepare the “Why XYZ?” type of questions from the bottom of your heart. You cant fool the interviewer. Also, always always respect the interviewer. I was down in energy later on. One should have a proper meal before coming for placements. Always be in touch with your seniors (wherever they may be). They can really throw gems of advice at the important instances. Do not worry about your interviews. Its futile. I think overall, I could have researched a bit more on the company cultures. Carry Red-Bull if you have more than 4 interviews. Also keep a sophie/thirdie always at your disposal. Switch off your cell phones when inside. I would prefer that you wear a suit. It gives a good impression. Don’t wear it for the first time on that day itself though. Do check if its good morning/good afternoon/good evening.

Round: Case Study Interview
Experience: The trick was here to recognize that even though the firm had several hundred client in each city, it was a few big clients who contributed to most of it's revenue and a distributed network targeting these few clients was the expected recommendation.

Round: Case Study Interview
Experience: The task was to explore possibilities of synergy in this acquisition. The case was based entirely on common sense and elementary mathematics. The interviewer wanted me to write equation showing how costs would reduce if the two companies merge.
HR questions were about strengths, weaknesses, MI etc

General Tips: 1.Pre placement preparation:
Work on your communication skills! It's absolutely necessary to be able to speak fluently with good  diction

2.Resume:
Consultancies look for spikes in your career. Spikes are the areas in the resume where you have shown outshining performance.

3.Case Studies:
Practice them in groups. Avoid technical jargon and frameworks.

Round: Resume Shortlist
Experience: I went through a few templates & took help from some seniors. I prepared a few drafts and then later made improvements. IT might be a good idea to prepare well in advance and get your resumes reviewed from seniors in the companies you are applying. As probably you'll get to hear a lot, focus more on what you have achieved rather than just stating what all you have done. Keep it simple and short. And don't add anything you are not comfortable talking about in an interview. I know many capable people who didn't get short listed for Mck/BCG just because they didn't think resume was a big deal.

Round: Case Study Interview
Experience: The case was simple. The interviewer said that imagine that he and I were flying together, he being an entrepreneur and I being the consultant. He tells me that he has motorcycle manufacturing business. His revenue has been steadily increasing but he is making losses. As he was not an accountant, he did not have any figures with him at the moment. After some discussion he told me that the sales were up and the costs had stayed the same. I figured that he was probably selling a couple of products and the sales of products which he was selling at a loss were increasing faster than those on which he was making a profit. That came out to be true. He was also selling auto parts apart from motorcycles but was making losses at the sale of motorcycles and sales of motorcycles has almost doubled last year while those of auto parts had stayed the same. That was all and we went back to HR questions. Another case was again pretty straight forward. The interviewer told me that his friend owned a multiplex in some suburb of Mumbai. His friend was making huge losses and had left him a frantic voice mail and wanted to meet him over the weekend. So I had to first give few ideas as to how to generate revenue, to make his friend feel better and then how to find the root of the problem. I think I tossed around a lot of ideas but I don't remember most of them. We planned to decrease cost of tickets but increase charges for advertisements and increase canteen rates. We planned to show soccer, cricket and tennis matches whenever it looked profitable and feasible. We also discussed coming under an Adlabs or PVR umbrella which will offer better bargaining power with producers. Then we also decided that it will be a good idea to conduct a survey in the locality and find the right mix of regional, bollywood and hollywood movies.

Round: HR Interview
Experience: A lot of HR questions interspersed with small cases like consider a factory on one side of a river and a town on the opposite side. There is only one bridge to cross that river and there is always a traffic jam on the bridge in the mornings and evenings. Give a few ideas to improve the situation. He also gave me a guess estimate to guess the number of white boards in use in India. And then he asked me to give arguments for an average educational institute to shift from black boards to white boards.

Round: Other Interview
Experience: This interview had no case. In-fact it wasn't exactly an interview and we just talked about his time at Mckinsey, their work in India, role of BAs etc.
