What Our Members Say About PrepLounge

I can say with 100% conviction that I would not have even passed Round 1 let alone get an offer from BCG without PrepLounge. As this is my 2nd time applying to Consulting, I know for sure that I was not prepared the first time and real-life practice and help from experts is the only reason I did well this time. I would recommend using PrepLounge to anyone who is serious about getting a job in Consulting!

Through constant mock interviews on PrepLounge, I managed to put into practice the case interview techniques I have learnt from casebooks and I felt a marked improvement every week. In short, I managed to pass 11 out of 12 MBB interviews, and secured 2 offers from McKinsey & BCG! I highly recommend getting an account with PrepLounge if you are serious about passing the interviews and getting into a top consulting firm! Cheers, C

The most precious thing is that there is a huge community on this website and the unique value is to organize training sessions with this community. What is really great is that the people on this platform are experienced and are giving great feedback to help you improve. The community is very large so you have the opportunity to arrange calls in a lot of different languages. I've trained with amazing people on PrepLounge who now got an offer in the MBB.

Dear all, PrepLounge has been my most important tool for my interview preparations. Thanks to my extensive preparations on PrepLounge and approximately 70 meetings, I received offers from McKinsey & Company, Bain & Company, Roland Berger and Monitor Deloitte. In my opinion, there is no substitute to practicing actual interviews with peers. Books can only give you theoretical background knowledge that might be useful. Cheers, Florian

Thanks to PrepLounge I received a full-time offer at the consulting firm of my dreams! The platform provided me not only with the relevant materials but also with a wide range of competent case partners to practice with. To give my preparation further polish, I joined a coaching program. All of the coaches were really supportive and helpful. Considering the opportunity cost, I found the program worth every penny and would book it again with no doubt. Thanks, PrepLounge!

PrepLounge is a great tool to prepare for any consulting related interviews. It helped me from Day 1 to talk to peers, to learn how you might solve a case, to learn from your peers' interview experiences and to adapt those learnings to your casing. I believe preplounge.com offers the best opportunity to prepare for consulting interviews since it reflects real-life situations how it might come up with a consultancy.

There are a lot of programs and products for case interviews. I decided to use PrepLounge because it allowed me to prepare for interviews with real people, so I got the real stress and real feedback.

I was a novice when I started the case handling, but with the help of various articles and structured methodology of PrepLounge, I got way better and learned a few tricks. I am applying for opportunities in the Consulting firms, and I am sure that I will crack the case which will come to my way. The only way to get better in case solving is... Practice, Practice and more Practice.

Via PrepLounge I got access to a lot of insightful resources while I also got to know a few great people who helped me crack a lot of cases and improve myself, to the point that I successfully got an offer from McKinsey & Company. I totally recommend PrepLounge! Only regret of mine is that I did not buy the premium version sooner.

PrepLounge has definitely been a game changer for my consulting interview preparation. - Great platform to practise with peers, learn from them and network - Cases well selected and resolution properly explained - Useful extra material about business notions - Interactive tests, project simulations and mental math tools

1# - Market sizing case: How many petrol stations are there in the US?

As mentioned earlier, there are many different ways one can approach this problem. I typically approach this following way: 1) What is the total demand for gas stations? 2) What is the demand for one gas station? 3) Find the total number of gas stations. To start with number 1, while I have no idea about the real ...

2# - What is your advice for a person who is starting an entry-level positon in management consulting?

Hi, Good question! I have worked for 5+ years as Project Leader at BCG. My advice would be: #1. Gain trust quickly. When you start, the most important thing is to gain people’s trust. No one expects miracles from you. Just do the basics right. Work hard, be focused, read your stuff twice...

Eric
BCG

3# - How to best structure for comparison with competitors to have a MECE approach?

A few remarks on this from my point of view (there is no wrong or right here). 1) Comparing the client/target with competitors should not fall under market. The only competition related issue that should be looked at in market is competitive intensity, i.e. how strong is competition between the different players. 2) …

4# - How to answer the question about being ready for the working hours?

In my view you can answer the question from two angles. The first angle is about working hours. Here I fully agree with Vlad, the key points would be about 1) Capability and willingness to work long-hours 2) Ability to stay steady and focused for long time and motivate team to do the …

5# - What's the best way to structure a revenue growth case?

It depends very much on the industry. In some cases (Growth strategy), I will use a broad structure, in others (e.g. “how to increase the excessive luggage revenues for an Airline”), I will use P, Q and the Process. Here is the broad structure that you can adapt to your industry: Analyze the market. 1) Size and ...

6# - What are good examples for 'best practice' cover letters?

I can't share any cover letter, but can surely help with the structure. An excellent cover letter for consulting roles should include the following: 1) Intro (name, current role in the current company, which role you are applying for and which company) - no more than 2 lines. 2) Why I want to be a consultant (this could …

7# - Should I mention this in a PEI?

I have to say that I found your experiences very interesting. In general, any experience can be successfully brought up during an interview as long as it as a learning side. In both of your examples I see many hints: Team-working, Analytical skills, Creativity, Sense of adventure and curiosity. These are all ...

Sara
Strategy&, McKinsey & Company

8# - Is it difficult to join McKinsey, BCG or Bain as an experienced professional?

I was an experienced hire as well, so can definitely relate. The hardest part for your will likely be to get an interview. McK is probably most open, assuming you have a specific expertise set that they need; BCG does also hire some experienced hires but that's rare; as for Bain... to my knowledge, they pretty much don't …

9# - How fast do I need to do math in a case interview?

First off, huge congratulations on your upcoming interview! To answer your question directly: accuracy trumps speed: I've never said “no” to a candidate who ticked off all other boxes, but was slow with maths. But I have said no to a candidate who had a great case but made so many mistakes with planning and …

10# - What are the position levels at McKinsey?

That is correct, the traditional track at McKinsey from bottom to top is Analyst > Associate > Engagement Manager > Associate Partner > Partner. Moving from one position to the next normally takes 1 to 3 years. Each one of the previous role develops from Junior to Senior (e.g. from Junior analyst to Senior analyst). Many …

11# - Decision framework to choose between McKinsey, BCG and Bain?

I started my consulting career at BCG in Germany, got promoted to Senior Consultant, and later switched to McKinsey to do work in several emerging markets. I have a combined 7.5 years experience in both firms and hence can give a good comparison from the inside: 1. Reputation & (perceived) ...

Sidi

12# - What are the typical work day hours at a major consulting firm?

Working hours depend on the geography. In Dubai, Singapore and Southern Europe hours are usually longer (my experience in Italy was 9am-11pm Mon-Thu, 9am-8pm Fri and 70-80% of weekends with some working activities). Hours also depend on the type of project (on average, the shorter the …

13# - What is the best way to learn frameworks for my case interview?

You often hear in conversations about structuing case interviews that you should not use standard business frameworks and concepts because they are too simple, and because every interviewer knows them anyway. It is most definitely true that you can't crack a realistic interview case...

14# - What is the difference between interviewer-led (McKinsey style) and interviewee-led cases?

Thanks for reaching out. According to my personal experience and the feedback I had from other interviewers in MBB/non MBB, the difference between interviewer and interviewee led is as follows: In an interviewee-led case, you will have to get the lead (ask the right question, go deeper in your analysis and make an ...

15# - How can I join MBB after working at a top 20/50 consulting firm?

I have known several people who joined BCG Paris after having work for a few years in other consulting firms (either top 20 or boutique/specialized). Evaluation criteria during cases interviews will remain roughly the same. Of course they will expect more maturity. They also keep track of previous interviews so they will …

16# - How to take better, clearer notes during case interviews?

This is definitely an underrated (but important) skill to develop when working on cases. Usually, the people I've worked with have adopted the same format you currently have with some minor tweaks: 1. Position of paper is horizontal (adds more space for the issue tree going from left to right) ...

Carlos
Deloitte Consulting, Cemex, BCG, Evercore

17# - What are good questions to ask at the end of the interview?

The last part of the interview is often used by interviewers to confirm the impression they got over the first part of the interview, which means: Situation A: They trust in your abilities and are likely to vote for you during the discussion round following the round of interviews - they expect you to show genuine …

18# - Preparation for McKinsey, Bain and BCG

Great to see you guys leveraging this platform (apart from your b-school consulting clubs) to find partners and crack cases. While you get into the intense prep, do take care of the following: 1. Get your basics/knowledge base right. Core subjects in grad school/MBA need to be thoroughly understood...

Gaurav
McKinsey & Company

19# - Why don't I get invited to case interviews?

I will try to give you a small checklist, but there could be numeruous reasons why your CV did not make the cut, and we can only guess. 1) Make sure you are well rounded (GPA, schools, extracuriculars, sport) BUT you need to have a SPIKE - you need to stand out, especially for MBB 2) CV - 1 page per decade of...

Jakub

20# - How to talk slower and "more senior"?

Guennael and Sidi both raise great points, but there's an observation to be had in the way that they presented these points. Both of them segmented their responses into 3-4 key items. Think about doing this in your verbal communications! That means: 1. Pause before speaking to gather your thoughts. The ...
