  1. David

    Nice book, many examples incl. solutions & explanations. I was able to solve all the examples within the given time and got 70-80% correct answers. It was certainly helpful for my BCG preparation.

  2. Paula

    I would recommend this booklet to anyone even before they start their application. The test and each part is well explained and summarised and the authors discuss strategies to score high. However, you should not rely on this information alone, but also start to practice as early as possible with the materials in this booklet, the links provided also the execises mentioned. In the end, I would say the booklet is a great guide, both for the chatbot interview and the real interview actually. Is saved me for the chatbot case and had big part in my approach and success for the live case interviews I believe.

  3. madhav

    This BCG case book exceeded my expectations. It deals intensively with each question type and how to learn the skills and then show them during the case. The practical part helps you practice them often and try again and again until you nail it.

  4. Tq

    Very clear and helpful!
    Great for learning for the Casey. Really helped me and I can recommend it to everyone going through the same challenge

  5. Zhiyuan

    On the whole, a good book with comprehensive tasks and extensive opportunities to practice that is very similar to my computer case. However, two links to a few practice resources were broken initially but quickly sent to me by Florian after I mailed to him

    • StrategyCase

      Dear Zhiyuan,

      Thank you for your kind feedback and for pointing out that the links were broken. I have fixed it now with a new version of the guide. All the best with your BCG interviews going forward!

      If anyone else is reading this: If you encounter any issues with broken links or missing materials, please contact me directly as during the day I will help you out usually within 1 hour.

  6. Belinda

    The book helped me a lot and I am glad I discovered it. The tips on how to approach each question type with a game plan, for example, make it easier to understand the case and monitor your speed and progress. I am glad to have discovered this trainer also for the primer on consulting math alone. There is a lot of information on how to approach and solve case math problems. I can recommend it to anyone who wants to work on or refresh their casing skills and habits. It has helped my physical casing skills as well.

  7. Vinnie D.S.

    I like the content very much and it is nicely presented. Clear learning points with progress plans, practice tests and questions that come with the sample solutions. Very relevant for the BCG Online Case and I can recommend it relating to my own test experience which was like the sample tests!

  8. A.R.

    This guide was recommended to me by a friend who works at BCG so that sold me. Was not dissappointed and absolutely recommend it to everyone who goes through their process

  9. Karin

    – Mandatory for applicants that go through the Casey
    – Possession of the book is not enough, you also have to practize a lot as recommended in the book and with the sample test (all provided)
    – You should also buy a good calculator
    – a treasure trove of various aspects of consulting interviews in general

  10. yaying

    The right book for preparing for the BCG test. And thanks to the sample tests, you can test yourself very well to see how fit you already are. I can only recommend it. It is definitely a very good supplement to overall case preparation.

  11. scott

    I took the bcg online case two weeks ago and one week later had my mckinsey interviews and for both purposes the book was perfect since both follow a very similar format (interviewer-led) and the questions are in the same style.

    I can definitely recommend this book as I was able to use it for more than just the casey. It covers a lot of general consulting case interview ground.

  12. Simone

    When I applied for internships last year, I failed several online tests because I was not convincing enough I guess because of being to slow. This year I invested the money for test prep, and invested more time and focused not only on interview prep. The result is that I passed the Imbellus games and the BCG online case. Some of the games and the questions in the real tests were really identical. If I may give you a tip: Invest in yourself, because that usually comes up far too short! It will pay off.

  13. giacomo

    I have been reading the book for the last couple days and trying out the accompanying tools and practice. Already the background information and strategy part was very enlightening. It helps that it is very practical and written in a very understandable way.

    The sample tests come as a bonus for me apart from the preparation and tips presented as it allows to implement what one has learned and integrated.

  14. Lakshmi G

    This book broke with my ideas of how to tackle the online case. With the help of a study plan, clear explanations, practice materials Florian illuminates the Casey tool well. It helped my thinking and made me consider new approaches to the test and the different question types. What I particularly like is that he does not beat around the bush but provides value with every chapter.

    What I also liked was that his writing style is easy to digest. Very pleasant. Therefore 5 stars.

    Conclusion: This book is very suitable for learning how to approach and manage the BCG online case and its practical application with sample tests.

  15. uk

    A prep book that is able to combine the online case preparation with important case interview principles in a somewhat entertaining way. In this way, the book provides the reader with a bridge between the online case and the actual case interview by showing that both are just two sides of the same coin.

    A highly recommended book on the BCG online case with food for thought and many practice opportunities!

  16. Santiago

    I work in the strategy department of a F500 companies working on the switch to MBB. I think this book is perfect for the kind of virtual case that I encountered during my BCG application. There are a lot of examples that you can easily put into practice with the materials and sample tests provided. All in all, a very good book,

  17. Umut J.S.

    Well structured and explained as in the McKinsey Guide that I purchased earlier. Anyone who has completed their studies going for BCG should buy this book. The most important components of the online case are covered and I found the detailed section on preparing and the sample tests for honing ones skills very helpful.

  18. W

    The recommendation I got is fully justified. Ideal if you need to get to grips with the BCG online test. There are two exercise books to go with the guide

  19. emile

    I did roughly 150 practice cases before buying this book.

    This book offers a good basis for “inexperienced” applicants. I worked through the book from front to back and it helped me to focus my preparation more and identify my remaining weak spots and adjust to the BCG online format. Nevertheless, many tips are useful and a real support for applicants with little or intermediate experience with case interviews.

  20. Pranjal G

    Must have for BCG applicants. Explains everything well, provides a clear preparation guidance, test strategies and practice opportunities

  21. jiaqui

    The book is written in a way that I can understand. Especially the sample tests are great for people who just want to practice everything and find their way back into the subject matter! I have been out of school and case practice for several years and I can only recommend this book to refresh and expand my knowledge, especially for such an online case method

  22. Akhil

    In preparation for the BCG case, I got this book to get back into the material of cases and online tests a bit. The sample tests are very comparable to the content of real case. In the book I found the respective explanations super to get back up to speed and to get the right approaches or solutions shown.

  23. Janne

    The book is really great to get insights into the BCG application and the chatbot case. It describes in detail what is important, what questions are used, how to deal with them, and what preparation is effective for different time budgets.

    I think this book is a great helper for anyone studying for their BCG case.

  24. sunanda

    + contains in detail everything important on the BCG test
    + the book also contains two additional sample exams
    + requires no previous knowledge
    + easy-going and pleasant style of writing
    + some tables and illustrations, which are very helpful
    + full of examples
    + well suited for non business people
    + extremely good value for money

  25. Annegret F

    Good book. A practical take on the the BCG online chatbot. It is important to adhere to certain principles and strategies – especially as a non business major – so that the case is successful. Good advice on preparation techniques. I enjoyed reading through it and it helped me tremendously in the session.

  26. Christian

    Very good structure. The book has a handy size and is quick to read while covering every aspect of the casey. If you don’t understand something, you can write an email to the author and you will get a helpful answer and solution. I am satisfied with the book and service. It remains to be seen whether it will help with the BCG case but I believe it will.

  27. Ceyda.

    Clear and stringent, extremely readable reference book for BCG applications. The price is actually quite cheap and more than justified. I am very enthusiastic about this book because it brought me clarity with regard to possible questions early on, explained all the the different assignments and provided practical approaches for all, including a ton of practice materials.

  28. Kathrin D.K.

    I bought the book for a the BCG recruitment case. In itself, the book prepares well for the case:

    – It is comprehensive and you can work through it with a quick pace.
    – I also find the sample tests very useful as an add-on.

    I purchased the guide in combination with the math program and the math problems in the course were much harder. That’s why I was able to solve the tasks in the real case without too many problems.

  29. Cyrille

    I bought the book because, as an engineer with little business background, I wanted to get up to speed for my upcoming BCG assessment. The ideas in the book are very clearly laid out and it has an excellent didactic structure. I can highly recommend it to everyone who is preparing for BCG. Although I could not print my PDF, I don’t think this has any disadvantage with reading comprehension. The explanations are also comprehensible and yet precise the sample tests are engaging – my conclusion: 5 stars.

  30. Fung Lam

    I purchased the booklet to review the casey material. I can recommend it for 4 reaons:

    1. The content was spot on and really well suited to the casey but also bcg interviews in general
    2. It was fun to work with the practice tests that are very similar to my experience
    3. The book is well written and everything is explained well in the respective chapters
    4. I received a free update after I bought it without asking

    Thank you for helping me pass the test

  31. bimpe

    I want to give this 5 stars. It is an indispensable tool for BCG and I used it to pass succesfully. It is easy to read, cheap and there are many valuable tips in it that I did not know about or think about.

  32. Torben Pa.

    Top source when it comes to learning how to ace the BCG case effectively and efficiently. All relevant aspects are included and described in an easy-to-understand way with plenty of examples and additional materials.

  33. Saurabh

    A wonderful book! First class preparation for the chatbot case.
    No matter how well you have learned business concepts or cases at university, this guidance is a must to approach the test.
    The flow of information is great and covers everthing! Formatting of the book, structure is good, the samples are just like in the real case.
    I recommend this book to everyone who is specifically preparing for BCG.

  34. Astrid

    Very helpful and recommendable!

  35. Julia

    I find the book was really helpful… It is well structured, explained in a way that builds up from the beginning and you are guided well through the individual sections. The test simulations show you what to expect and help you to check your own progress. It’s hard to imagine working through all the material online without a book like this. A real supporter for you BCG preparation!

  36. Max

    I bought this book to prepare for the BCG online case and must say that the book gives a good overview of the types of possible questions and the setup. Not only do you get to know the types of questions, but you also understand how the questions are designed and work. It teaches you how to fish, because you know the way to the goal.

    I think this book is absolutely worth working through and the trial exams are very similar to the real case I went through.

  37. david

    This book prepares you optimally for the BCG recruitment case. It covers a lot of ground:

    1. Content on the test, a long section on preparation tips and exercises and test-taking strategies
    2. Other BCG testing formats (that were not relevant for my case)
    3. Sample tests that are very similar to the real case

    I felt very comfortable going into the the case because the authors highlight how you can use your normal case prep also for the online case. The information is very focused on helping you succeed.

  38. estefania

    The book contains many exercises and sample tests. The content is very well explained. It is the perfect preparation for the BCG case!

  39. Maya


    – very comprehensive; covers all questions and question types of the test
    – many practice exercises and resources; very similar to the real case
    – more comprehensive and better than tests you find on the internet
    – lots of practical tips
    – info is also relevant for the in-person case interviews
    – low price compared to others


    – could contain more full practice tests

  40. luca f

    after going through the imbellus prep book I expected a similar quality prep for bcg and was not disappointed. many great tips and explanations and strategies to tackle the robot case. could go for more to be honest

  41. Jan

    I found the sample tests very good, at least up to par with the real case and therefore also tricky. The content and infos are very detailed and helpful in this guide. In any case, a good investment to prepare and check your current level to see what you need to improve and then also prociding a plan and exercises to help you do that.

  42. Sascha

    I liked the book and tests as a motivation and guide to the online case. Florian writes in a relaxed and likeable way which made this dry subject a little easier to digest and he also took away some of my fears. It also helped me a lot that he thought over every little step for the different sets of questions and explained it all in detail.

  43. phillip

    The book really gives very helpful tips on how to approach each sub-topic on the chatbot case with a structured plan and approach. The strategies described have helped me pass and I also learned some things for the BCG interviews. The general tips have especially helped me to get the rather unimportant questions such as logistical details about the test day answered.

    All in all, this is a good book that you should have read and practiced with before taking the BCG online case.

  44. oliver

    the solution strategies and exercises are a great help in internalising the different types of tasks and the guide also contains a lot of practical additional information about the test and BCG overall. I felt like I performed badly on my test as I was quite nervous while taking it. happy to report that apparently my performance was good enough as I just received positive news from bcg. 🙂

  45. S.

    I was working with Florian on the McKinsey interviews and received an offer but due to geographical preferences I have also applied at BCG and used his guide to prepare for the chatbot interview. The book is an excellent tutorial for the real test and helped me to approach it with more confidence and skills. If you are thinking about BCG interviews or the online case you can’t go wrong with this well-researched and elaborate guide. S.W.

  46. Pamela

    The book is very helpful, because I didn’t know where or how to start learning and preparing for the test. This is how I approached it:

    – I started with a self-test as recommended by the author to see how the online case looks like and figure out what my main issues are
    – I read through the guide and then used the 2 weeks preparation plan with some minor tweaks for my personal situation
    – I practiced the recommended exercises religiously besides the case prep every day and have to say that it is very synergistic and also benefitted my analysis skills for the live cases. I really tried to implement all tips and tricks directly
    – Every 3rd day I did a mock test to see how I am improving

    I received positive feedback on my result from HR 2 days ago 🙂

  47. Gustavo

    Excellent guide. I was looking for something that was as close as possible to the BCG test and this guide is super complete, lots of material with very clear strategies and practice material, comes with much more information than I expected, and proposes a preparation time plan of 2 or 4 weeks. It comes with personal support. Highly recommended!

  48. Anika

    Good for theory and practice that contains a lot of genuine information and preparation advice on how to deal with the chatbot, what/how to prepare, what to pay attention to. Happy with the purchase and my outcome

  49. Claus

    I found it a valuable addition to my case training due to excellent content and low price and learned a lot of things. It is a good mix of theory and practice materials. The sample tests are very similar to the real one.

  50. A.

    Without a doubt, the best BCG Online Case prep out there. I already bought the McKinsey guide, so I trusted their training materials and was not disappointed. With the prep I felt very confident, I experienced no surprises during the test and evetually cleared it. I shopped around a bit for this one too to have the direct comparison.

    I left some feedback on the quant questions and the guide was promptly updated and I was sent a new version 2 days later for future reference.

    All in all a great experience and customer service. 5*

  51. Yasmine H.

    Excellent primer and deep dive on the Casey. I bought the book to acquire the basics of the BCG case and was surprised to find the level of depth and detail that is conveyed from start to finish.

    While preparing for cases, I quickly realized that I am often struggling with the basics. These such as chart interpretation or math are explained in this book ingeniously in small steps using examples and with many exercises to go from. From there it expands far beyond and provides you with step by step logic for the complete preparation, the different question types, and the test-taking tricks. You can see the amount of work and case experience that went into the creation by the team.

    I ”only” had to sit the Casey and no Pymetrics or Video Interview but I am sure the material covering these is equally valuable.

  52. Sven

    Useful for the preparation

  53. Joana

    I received the PDFs right after purchase and I really appreciate the format of the book: a theoretical part followed by a guided practical part. All the different interview types and tests are well described and explained. If you want to practice, I recommend the two simulations of a Casey test, which are very similar to the test I got from BCG.

  54. Daniel

    Good resource. Gives a good overview of all tests and provides suitable exercises with solutions.

  55. Shawn

    Truly great product. It is full of great tips and prep advice for the OCSA but also beyond that I could learn a lot for my BCG interviews. I was happy to find practice tests apart from the one provided by BCG. The tests are very similar to the real one but I feel the math questions were a bit harder in my case.

    • StrategyCase

      Dear Shawn, thank you for your kind feedback. We have noted your point on the math difficulty level and are currently adjusting our sample tests to reflect that based on other feedback we have received. All the best, Florian

  56. Barbara

    I prepared on short notice after a referral and a faster than expected invite to the chatbot case. I found this guide very helpful. Great detail with a wide range of topics covered that help you prepare and succeed

    The 2 mock cases were very similar to the one I had during my interview about a company that is selling agricultural vehicles

    Thank you for that wonderful product.

  57. J.Y.

    I would give the guide 4 out of 5 stars since there is some practice in preparation for the Chatbot AI case, which is not directly covered in the guide. The handbook tells you exactly what to expect, discusses strategies to take the test, provides exercises you can do and points to further (all free) practice resources. This is all excellent and very helpful. In fact, I applied the strategies in my assessment and it worked. -1 point here since I would have loved to have a sample test included for practice. I think this is the only thing that could make the guide better (in fairness, this is also not advertised to be included in the guide).

    But I rated it 5/5 because I had some questions and Florian took the time to call me and go over them. I did not expect that level of customer service for this kind of product.

    To sum up, I can definitely recommend the guide and the customer service, especially at this price. Consider adding one or two sample tests in future iterations as we discussed. 🙂

    • StrategyCase

      Dear J.

      Thank you very much for your message and kindness. We are currently working on adding realistic practice tests in addition to the questions that are already in the guide and it should be available soon.

      Take care!


  58. G.

    The booklet gives detailed understanding of what is expected from you for each assessment, how to best train for it and how to tackle each question. I was going through the AI chatbot 2 weeks ago (benelux) and passed. I expected it to be harder.

  59. hei

    The pdf contains everything you need to prepare for the bcg chat case. Unfortunately, it does not relieve you of doing the exercises and preparation to master the skills, but it leads you on the right path. The book guided me in my preparation for the first round, and I passed it last week.

  60. Fabian

    The book is well structured and easy to understand and follow! It helped me fill a few blind spots I was not aware of in my approach and the questions in the chat case. Great as an extra help and I can recommend it. It is priced very fairly for the value you can extract

  61. markus

    A must if you go through the BCG hiring process. The insights I gained benefitted me more than just for the chat interview. Everything is covered, succinct and besides the tips on how to prep, approach and answer questions there is also lot of wisdom to develop a consultant’s mindset that I use now for the cases.

  62. nichola

    I’ve been using the book for the last week and a half to prep for the chatbot case that is apparently a new recruiting element. I am impressed with the level of detail of information and the insights into BCG and the approach to the different questions. It took away a lot of anxiety for me.

  63. Robert

    Amazing value for money. It helped me structure my preparation, identify my weaknesses, and taught me how to work on them. I found it useful for learning the quantitative methods and the nuanced approaches to the different question types with a decision tree.

  64. Emily

    You address all points well and it seems like a comprehensive prep guide. But do you have any information on the video recording?

    • StrategyCase

      Dear Emily,
      Thanks for reaching out and for the kind words. Regarding the video recording: Are you referring to the video recording of the Online Case or the video interview? We have written about the Online Case here, with some information on the format that includes the video summary. Fundamentally, nothing changes on how to prepare and how to approach each question. As for the video summary, treat it like a typical summary of a case interview question (state your recommendation and then provide some supporting arguments based on your analysis).

      If you are talking about the one-way video interview, which is not related to the Online Case, check out this article here.

  65. Alexandria

    good program that covers all important elements. perfect as a standalone resource to guide and expedite my preparation. you still need to put in the work and work on your weaknesses etc.

  66. c.f.

    good intro to the bcg test, very structured and nice exchange after purchase on some discussion points.

    • StrategyCase

      Likewise! You raised some very interesting facts. 🙂

  67. steph

    I feel very confident and motivated having read through the pdf once and having drafted my preparation strategy in line with their recommendations and plans. From my current pov the book gives you exact expectations on the test and shows you what and how you can prepare and also how to approach the actual test and be quicker.

  68. Michael S.

    Stellar advice, and prep plans. I would give 5 stars if you guys included a practice test or several more practice questions.
