I come from a pure technical background with no prior knowledge in case solving. How can I be ready in a very short period of time knowing that I have a full time job? Or can we reschedule the interview date? Can I re-apply later in 2021 without repeating the assessment test?

I have a similar background so it might help you.
So here is how I did my prep : there was two phases. Phase 1 to prepare for the case and phase 2 for the fit (both are really important).

Phase 1 : preparing for the case

  • I read the case in point. I learned the principal framework and read the transcript of the case interview that are offered. It's useless to learn the whole thing by heart. Learn the framework in a smart manner which means learning the framework but most of all understanding why there is each part in each framework and not others. You will quickly realize by yourself that some parts in the framework aren't that important while other can be treated differently. But it gives you a nice basis.
  • Practice cases on preplounge. The first case was terrible. It was seriously pathetic but that was a very good and necessary experience. I didn't really know in which direction to go or to apply the framework and so on. But i kept practicing. I did between two and three sessions per day (three is a little bit too much IMO : you're washed out for the third one and don't really gain much from it). Two sessions means four cases (two as interviewer and two as interviewee). This is very important to do both as you will see the other perspective which will help you to drive the case.
  • I practiced until I got confortable with cases. When you start to see where the case is going, don't need to take too much time on delivering your structure and start to realize on your own that this is the end of the case. This time varies from person to person but you need to practice until you reach that point. I didn't prepare for specific type of case or industry. I did anything that was offered. There is no point IMO to do only specific industry or type of case (profitability, etc.) . Quite the opposite.
  • When I reached that point I booked a case with an expert. Very important to gain confidence and see what was wrong and could be improved. My feedback was very positive (not much to improve)
  • Then I knew i was ready to go. So i kept practicing cases but not as often. Only two times per week. Just to stay sharp. And every know and then I only read previous cases to refresh my memory on what i could have improved at the time and what was important.

it was only as of this moment that i started to do interviews.

The duration can vary from person to person but I would recommand to estimate the preparation to be at least 6 weeks. In total it took me around 30 cases before getting really confortable, seeing any case as a nice exercice instead of being stressed by it and being able to deal in a correct way with all the cases I was given. After those 30 cases and the session with an expert I maybe did between 5 and 10 of them (at most). And when i had interviews I always did on prep session per week (two days before the real interviews). Those final prep sessions were all simulation of real interviews (so FIT+case).

In the meantime, every now and then I read the economist, analysis from Mac Kinsey, BCG and Insead. It doesn't take long. Half an hour every couple of days or something. I personnally read it in the subways or while i was cooking. Just to see the problematic and gain some insight. I also did some market sizing on my own every now and then. It takes few minutes and you get confortable with that very fast. I also watched few videos on Youtube since there is a lot of material from former or current consultant (personnally i watched rocketblocks but you have plenty of choices).

In parallel, I also prepared the fit part.
I just did it every now and then on the side. Nothing too systematic but a constant effort. It was always in the back of my mind and then i really practiced it during 1-2 weeks.

It can seem like a lot but this is manageable. Really. The only difficult part is to understand how it works. This is the only bottleneck to crack. With your background you already know how to read data and plot and are probably already confortable with numbers. So you will not have to work on those parts that much compared to people with other background. People insists a lot on the "business sense" but you'll see that at some point it's nothing more than simple common sense.


Among my inner circle we were 7 people that tried to go into consulting over the last 2 years with scientific background. None of them had any experience in business. Only one didn't make it. Among the 6 that made it, 2 out of 4 made it to MBB. The other two (I was one of them) didn't shoot for MBB (because they didn't want to) and joined tier 2 and small boutiques (same for the two that failed MBB).
In total, I personnally did a little bit less than 10 interviews with three firms (some firms have two interviews per round). And i always made it to the next round. And I'm far from being a genius or anything. When I got the offer from the company i liked I stopped the process with the other two, so there is no guarantee I would have had three offers if I kept going.

I'm not saying that it's easy

Far from it. But it's definitely doable. It takes motivation, preparation and dedication. But you can do it even without any background in business or cases experience.

Good luck and don't worry. It's definitely worth it!

Hi,

Please reschedule your interview. Unless it's on-campus recruiting (and from your words looks like it's not), you can choose any date that fits your pace and schedule.

  • There is absolutely no penalty for rescheduling
  • You can always tell the interviewer directly that you need time to prepare. They totally understand this - no one is interested in your failure / spending recruiting budget on failed candidates
  • If you are an experienced hire - the company is interested in your expertise and they understand that you'll have limited time to prep with your main job

Take at least 2 months to prepare (assuming you have a main full-time job)

Best

Hi there,

I highly recommend you reschedule your interview.

McKinsey will not mind and this does not ding your chance at all.

Now, this assumes that you are not interviewing as part of school recruiting (as you have a full-time job). If you in a recruiting cycle, you should have already prepared. As you're an experience hire, you absolutely can (and should) reschedule.

You will not have to re-take the assessment test.

Well done on passing the assessment! You have two options:

Risky

Plunge in, practice a lot with friends and hire case coaches on weekdays/weekends. Spend some $ on this but you will make this up in no time once you land the offer & start working. For this to work you really got to have self belief and genuine desire to make things work quickly.

Non-Risky

Take your time, prep well and postpone the interview 3 months out. Come up with a good reason/excuse and tell HR.

Good luck!

My recommendation is to take at least 4 weeks - see below for the detailed structure. However, you can always ask to delay the interview if it is scheduled much earlier than that. It doesn't hurt your chances to ask for a delay. Depending on your intended starting date, they might show some flexibility. When you do so, it's totally OK to tell them straight away that the scheduled date is earlier than you expected and you would need some more time to prepare.

To structure your case prep, here my general recommendation:

In my experience, practicing 15-20 cases is sufficient, if you do it strategically. My recommendation is as follows:

  • Read up on the typical approaches and standard frameworks to get the concept.
  • Then, do 5-6 cases to get a practical feeling for what a case is like. Start with easier ones - e.g. market size mini cases, simple profit tree cases, etc. This will help you develop a rudimentary sense for how cases work
  • The next 5-6 cases should cover cases from all major types and help you gain the experience and comfort with standard frameworks and the thinking required for solving the cases.
  • Lastly, you will want to do 6-7 cases to hone your skills. Practice with people who understand what they are doing - experienced interviewers, coaches, etc. that can give you 1-2 main items of feedback after each case that you can then practice to apply and improve on in the next case. During this time, you should also practice to move away from off-the-shelf frameworks and tailor, or - even better - develop your frameworks specifically during the case.

The further you move towards the final interview, the more important it is to practice with experienced interviewers. While you can easily ask any friend or practice with peers for the first few cases, you should aim for qualified, professional feedback as you approach the finishing line.

However, keep in mind, that this requires a strong plan and strategic approach to the preparation. I regularly see people doing 30-40 or even more cases. While this can also lead to success, in my eyes, it is a bit of a waste of time, especially for experienced hires that often also have a regular job to do while preparing for the consulting interviews.

Let me know if this helps. I'm also happy to elaborate any of the above in more detail. DM me if you like.

Hello!

Congrats! My case was a similar one, and thankfully I had the Xmas days to dedicate my full time to it, back in the day -which makes me feel old!-.

You can for sure re-schedule, I did myself.

In any case, no need to panic, can be done. You have 2 main workstreams ahead:

1. FIT INTERVIEW

The "Integrated FIT guide for MBB" has been recently published in PrepLounge´s shop (https://www.preplounge.com/en/shop/tests-2/integrated-fit-guide-for-mbb-34)

It provides an end-to-end preparation for all three MBB interviews, tackling each firms particularities and combining key concepts review and a hands-on methodology. Following the book, the candidate will prepare his/her stories by practicing with over 50 real questions and leveraging special frameworks and worksheets that guide step-by-step, developed by the author and her experience as a Master in Management professor and coach. Finally, as further guidance, the guide encompasses over 20 examples from real candidates.

You can see plenty of reviews from candidates who purchased it already.

Furthermore, you can find 2 free cases in the PrepL case regarding FIT preparation:

Intro and CV questions > https://www.preplounge.com/en/management-consulting-cases/fit-interview/intermediate/introduction-and-cv-questions-fit-interview-preparation-200

Motivational questions > https://www.preplounge.com/en/management-consulting-cases/fit-interview/intermediate/motivational-questions-fit-interview-preparation-201

Feel free to PM me for disccount codes, since we still have some left from the launch! :)

2. BUSINESS CASE

You don´t have any more time to the classics of Viktor Cheng, "Case in point" book, etc. You need to get hands on asap:

1. Practice cases with partners asap, as many as you can do.Find experienced partners who can provide a good feedback

2. Practice your math skills, both in your cases and with ad hoc exercisess, such as:

1. ​Multiplying double digit numbers (https://www.youtube.com/watch?v=6ndkkPZYJHo

2. Leveraging math tools (Mimir math for iOS), Math tool on Viktor Cheng website to practice

3. Ensure you have a good overview of the ​most common case types:

1. Profitability cases- basic profitability framework.

2. Idea generation cases: for any specif issue

3. Growth cases: market penetration, new product launch, product mix change, etc.

4. Pricing cases

5. M&A cases

6. Valuation cases

7. Value chain cases

Given you are under this much time contraint, consider working with a coach to foster speed and ensure you have a tailored plan to be very targeted. PM me interested!

Hope it helps!
