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

10.450+ Career Questions Answered by Our Coaches

1# - How to answer: Why consulting? Why McKinsey/BCG/Bain?

1) Be specific; 2) Make sure your answers reflect what matters as a consultant; 3) Don't focus on the glamorous aspects of the job; 4) Mention instances where you think consulting has had a big impact on a company or industry and why this is important to your decision making process.

eBay, McKinsey & Company

2# - How to answer: Give me a reason why I should not put you on a project!

This is a great/tricky question! It's a disguised "weakness" question :) The key here is two-fold: 1) Your weakness isn't really quite a weakness in the right context (e.g. I get really committed and sometimes forget to take care of myself); 2) You've learned (from some interesting experience) how to tame the weakness.

Boston Consulting Group, Appian Corporation

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

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.

Deniz

BCG, A.T. Kearney

4# - Has anyone tried the new McKinsey Imbellus Problem Solving Game? Any tips/lessons learnt?

If you are into video games, you are in luck! If not, it might be a time to start. Candidates report that the Imbellus assessment reminds them of the popular category of “tower defense” games, in particular, Kingdom Rush and Planet Zoo.

Strategy&, McKinsey & Company

5# - Is it always important to have a structure when being asked a specific brainstorming question?

A good structure doesn't need to be rigid. What matters is that you capture the key aspects of the issue, which requires you to be flexible and customise as needed. The branches in your structure can totally include creative ideas. You just need to get your creativity communicated in a structured way.

Emily

Grab, BCG, Shell

6# - McKinsey final round: What to watch out for?

As an ex-Mckinsey consultant and part of recruiting team, here is my perspective: Keep the following things in mind while preparing for the Partner interview: 1) Better synthesis and conclusions; 2) Comfort with less structured case discussion; 3) Consistent stories and deep dives.

Gaurav

McKinsey & Company

7# - How's life like as a Partner vs an Engagement Manager vs an Associate?

Here are my thoughts on travel: 1) Associate & EM: Usually, traveling engagements would make you be out from Monday morning to Thursday nights. Occasionally more for workshops; 2) Partner: Much more travel expected, not only to touch base with the different teams but also to attend client events, etc.

Clara

Instituto de Empresa Business School, Amazon, McKinsey & Company

8# - Can I get into McKinsey? If so, which position should I consider applying for?

Your career sounds very interesting! In general, the criteria McKinsey is looking at for business students are the following: 1) Being among the top 5% in Bachelor or/and Master degree; 2) Type of business school/university; 3) International experience; 4) Professional experience; 5) Any social activities

Giulia

Goeller Consulting & Coaching, McKinsey & Company

9# - What do consultancies expect to read in my CV?

Use a simple, yet powerful CV plan: education, professionnal experience, projects and business games (optional), additional capabilities (languages, technology, extracurricular). Keep it simple: Two colours maximum. Highlight the important parts. Do not mess with bold and italic.

Norah

BCG

10# - McKinsey hierarchy: What are the different position levels?

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).

Jacopo

BCG, Kearney, Vistaprint, Bain & Company

11# - How to build up confidence and look smart and sharp in a consultant role?

Building confidence is always a tough thing in consulting where everyone is super smart around you. My 2 pieces of advice are: 1) Focus on your strengths. What makes you unique? 2) Don't ask for permission, ask for forgiveness. It reflects the leadership and ownership mindset that you have to possess.

Réka

McKinsey & Company

12# - How to answer: What are your weaknesses?

For all the fit interview questions, it is important to have a proper structure to apply in the answer. A good framework would be the following: 1) Say which is a "good" weakness, that is, a weakness which is not a red flag; 2) Say what you are doing to improve it.
