Interview Preparation Tips
Experience: CASE 1:
I started by trying to get the prerequisites of going global demand, type and size of market, capital, project differentiation, management, logistics. My major mistake was delving too much into depth.
CASE 2:
He asked how you increased revenues?
I said....Everything depends on the elasticity of demand. You might want to increase sales or increase prices and reduce sales. Then he said, we increase prices or demand and assume the other to be constant.
How do you increase prices?
I said you just quote a higher price. Then he said that there are different seats in an airplane. That kind of tinkering you can always do even if you want to keep the revenues same

College Name: IIT BOMBAY
Interview Preparation Tips
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: 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: McKinsey interviews are mostly case study based. So prepare accordingly. Once you get shortlisted they send you a ton of material, search for a “Vault” case book amongst this pile. Reading that should be enough ;). First read the basic material by you and once you are confident enough make a group of around 3 people and practice case studies.
I guess this job opportunity meant a lot to all of us and it did to me too. I became nervous and that severely affected my performance and moreover I looked under confident. Take on every interview as if that job doesn't mean anything to you.
General Tips: Internship: (attention third year people!)
When it comes to the placement interview, internships play pivotal role. There are rarely any interviews where the interviewee isn't drilled on their internships. So, please don‟t treat an internship as a paid vacation. Good work done during the internship gives one the confidence that can very well bowl the interviewer over (as it did in my case :D). Believe me confidence does much more than get you a job; it determines success and failure in most
undertakings. Internship gives you the first chance to build that up … use it!
Pre Placement Talks:
Please attend the ppts of at least those companies which fall into your sector of interest. At ppts you get to see a lot more things than the boring presentations and the pay package. Most companies bring along with them alumni who have spent a few years in the company. Observing or interacting with them will give you a good assessment of what you are going to be a few years from now if you join that company. For example I observed that alumni of XYZ Company were not as upbeat and confident as alumni of ABC Company (names have
been hidden on request ;) ) even if XYZ was paying plenty more than ABC. I knew then and there that I would want to join ABC and never applied to XYZ. Be sure to utilize them and be sure to clear all your doubts and conceptions. Once you start attending presentations you will observe junta asking questions just to score brownie points with the speaker. Believe me it won't help one bit in landing them a job!
Resumes:
Making an appealing resume is the single most important step in the placement process and IITK is notorious for its bad resumes, so attend workshops. Like most IITK junta I sucked at making a resume (and still do), but whatever little skill I have, I got through workshops. One workshop I would advise everyone to attend is the resume making workshop of McKinsey. Get your resumes checked and edited by those who have been through placement especially by those from other IITs (I know this will hurt a lot of egos, but IITB's resumes are some of the best. Those dudes have mastered the art of making an impact with whatever little they've got, while we excel at doing exactly the opposite :P). Prepare an impactful resume and don't submit the same resume to every company, make changes based on the profile.
College Name: IIT KANPUR
Interview Preparation Tips
Experience: Since, first short listing was done on the basis of resumes, so again it’s very important to highlight some spike in your career in the best possible way.
Round: HR Interview
Experience: The interview had 2 rounds initially after which one shortlist was given. In the first one, after asking some questions from my resume, like why consulting, about internship,etc..I was asked a case to estimate the washing machine market of India..I was asked to think and come up with some answer and take as much time as I want. I just focused domestic market but was then asked to look for industries also L...I lost some track here and was not able to clearly see what is the market to washing machines as far as industries are concerned apart from textiles...then I was asked to list out the factors of buying a new washing machine, I said the obvious ones and then was asked to come up with a number depicting the number of machines which will be sold next year..I was not at my best but somehow got some answer which the interviewer said is ok and the interview ended up in 30 minutes.
Round: HR Interview
Experience: Later on, for the second interview, a partner called me in. He asked me about my pre IIT experiences and about my family background. Then he gave me simple case to calculate the number of cricket bats sold per year in India and then the market of this commodity. I did the case quickly and told him the steps and final answer which he said that that looked somewhat on the lower side and then asked me to leave. I asked me some questions and the interview was over in 15 minutes!!! L...shortlist came and I was not there.

Analyze the target audience and their travel patterns
Consider the route network and frequency of flights
Factor in the aircraft capacity and load factor
Forecast the seasonality and economic conditions
Collaborate with industry experts and stakeholders
Use data analytics and modeling tools for accurate estimation
- Q3. Why consultancy? What will you do if all consultants die one fine morning?
Interview Preparation Tips
Experience: Answer 1) I took a really long time to do this one, and I had only got as far as the consumption of vodka by women when the interviewer asked me to stop. She was not exactly encouraging/helpful and I guess that slowed down my responses. When I asked her if I could wrap up the guesstimate, she told me it would not be necessary
Answer 2) There was no real case here. The interviewer was a cheerful man who just wanted me to discuss how to go about starting an airline. He asked me to estimate no. of passengers. I divided the population into urbanrural, business travellers-tourists, etc (in steps of course, but nothing extraordinary). He seemed to be pretty impressed and was generally chatting with me for almost 15 mins about his experiences in McKinsey.
Round: Interview
Experience: I was asked to walk through my resume. Apart from the regular questions about my projects and internships, I was asked the one question which I was expecting since morning: “Why not research?” I was also asked about my Yantriki victory and my tenure as Speakers’ club convener. A large part of the interview was also devoted to “McKinsey vs. its competition”
General Tips: Sleep well, wear comfortable footwear (Girls, please stash away those high heels for post-job treats and NOT interviews, they almost killed me), don’t starve yourself. If you have back-to-back interviews, sit down for a minute between interviews and take deep breaths, it really helps. Now let’s cut the chase and get to preparation
PPT : Attend PPTs of all the companies that you are interested in. It will give you a good idea of the kind of people you’ll work with, apart from the work itself. Stick around after the PPT and talk to your seniors who are working with the company. Wait for the pizza, there’s always enough for everyone.
Resume : Don’t try and squeeze in too much into your resume. Going by the experiences of my batch, I think companies looked for well-rounded individuals and not necessarily DR1’s or managers and CGs. Needless to say, do not lie or exaggerate. It is disgusting, and in most cases, it will be obvious too.
Interviews: Please don’t prepare answers to the last word, but think about some common questions: strengths/weaknesses (a little introspection never does any harm) and of course, “Why consulting?” (or analytics, etc). Go through your resume and think about what you have learnt from each experience.
College Name: IIT BOMBAY
Interview Preparation Tips
Experience: McKinsey has an aptitude test, but the test results don't have a significant weight in final decision.
Resume shortlist for consulting companies is perhaps the most competitive among all firms and therefore,
in the interest of meaningful utilization of time, it's best to start case study preparation only after the shortlist is out. There's typically little more than a month between then and placement day, which is more than enough to prepare for any interview.
General Tips: Application process to all companies starts typically with a resume shortlist and therefore it is of utmost importance to write a good, impressive resume. A lot of people with great credentials fail to make this initial mark because their resume is poorly organized. It's good to have resume points, but it's equally important, if not more, to write them properly. Writing a perfect resume is an art that needs to be learnt
and God bless McKinsey for conducting an amazingly helpful workshop on resume writing.
It's a great idea to attend the workshop even if you are completely sure of never joining McKinsey.
Resume-writing is an iterative and time consuming process. So, best start a fortnight before deadline. Remember that it's a one-time effort. Once a good resume is ready, it can be used throughout the placement season with minor modifications. Do it once and do it correct. It took me about four or five iterations to end up with my final resume. It's a good idea to show the resume to lots of colleagues and seniors and challenge them to tear it down word-by-word.
