Stuck with a Brain Teaser question: what is the best reaction?

What is the best reaction to have during an interview if you happen to be stuck with a Brain Teaser question for which you don't find the answer?

It doesn't happen to me so often...but yet it happens. I wonder what is the most professional reaction.

Antwort auf Frage: How to proceed when I get stuck?

Hi,

I think there's a couple of things you can do in that situation.

  • First, take a deep breath (and/or a sip of water if you have a glass nearby)
  • Then take a moment to recap what you have learned up to this point and what you still need to find out in order to adress the main question at hand (this helps you regaining clearness on the big picture and where you are on your "roadmap" as defined by your initial structure)
  • Outline how these sub questions can be answered, and what kind of data/information you will need to do that
  • Double check whether data or information provided by the interviewer at an earlier stage is now getting new relevance
  • Don't forget to take the interviewer along and let him participate in your thinking process - think out loud!
  • If you are puzzled by some obvious contradiction, actively discuss this with your interviewer! Oftentimes an interviewer will wait for you to explicitly verbalize what combination of findings is puzzling you before gently giving you guidance.

This process should allow you stay calm and composed while regaining a grip on the problem at hand.

Cheers, Sidi

Two years conulting experience, went through lots of interviews and coached several candidates to MBB offers

Hi, good question! 
Probably somewhat depending on your interviewer, but this is my view on it.
In this situation it's important to try to showcase as mluch of your consulting skills as possible. Be transparent and admit you're stuck with this. Communicate clearly, explain why you do not see the appropriate solution and suggest to brainstorm together about it. 

  • You show reliability. You're honest and open and don't start making stuff up
  • You show communication skills. You can explain concise and accurate why you're stuck.
  • You show proactivity by suggesting to brainstorm together and make a first attempt/proposal for a solution

Hope this helps!

Antwort auf Frage: Lost in middle of case?

Hi Anonymous,

as for your first question, there are two things you can do when you get stuck and want to avoid silence:

  1. Repeat all the information until that moment
  2. Ask for one minute of time to think

You may also do both the steps together in the mentioned order. At the below link, you can find an example of how you can do so when you have to brainstorm, together with some suggestions on how you can structure brainstorming:

https://www.preplounge.com/en/consulting-forum/how-can-you-brainstorm-in-a-structured-way-during-a-case-study-interview-436#a875

As for your second question, there may be two scenarios:

  1. The information is relevant, but not critical to solve the case. In this case you should keep analysing the current branch you are, and then potentially move to the other.
  2. The information is relevant and critical to solve the case (you should understand that as you should get hints from the interviewer that he would like you to concentrate there  - eg he repeated a couple of times it could be interesting to analyse something else, or stressed a bit more that particular area). In this case you want to move to the new branch, making clear that you are doing so in order to prioritize the action to meet the client’s goal. In case you don't do so, you may lose points, as the interviewer may assume you are not able to follow hints and prioritize tasks.

Best,

Francesco

Antwort auf Frage: How to proceed when I get stuck?

Hi,

When you get stuck there are 2 options:

  1. You ask further questions
  2. You make a new structure to drill down further

1) You ask further questions. There are 4 types of questions that you can ask. Basically you can never get stuck if you ask one of these questions:

  1. You can ask for a historical data
  2. You ask for the comparable data of the competitors / internal benchmarks
  3. You can ask for a further segmentation
  4. You ask to describe the process behind the particular number

The 4th question is probably the most important if you get stuck. For example, if you know that the sales department is not performing you can ask the interviewer: "Could you please tell a bit more about existing sales process?"

2) You ask for 30 seconds and build a new structure. The most common feedback on the interviews is "You are not structured enough". To avoid this you should always be structuring. These structures can be both fully MESE issue trees or frameworks or a combination of both.

For example, if you find that we spend more time on cleaning the job shop than the other division you go with the following:

  • The frequency of cleaning * Time spent per one cleaning
  • If we find that the frequency is the same, we structure it further into People, Process, Technology

Best!

Antwort auf Frage: What's the best way to move on from getting stuck in a case interview?

Hi Kay,

During the case interview several dimensions are evaluated.
It happens that a candidates get stuck on a specific topic and yet perform very well on other dimensionss. In that case this can work out.

In addition keep in mind that the level of expectation is higher as you progress in the rounds. So this has better chance to work out on 1st round than on 2nd. However there might a special note on your folder for the next interviewer to specifically check one particular dimension

To be completely clear, let me give you a few examples of situations wehre candidate did not perform 100% welle but could work as well ;

- Situation 1 : candidate stuck at brainstorming, but perfomed well in case resolution and structuring of the initial issue

- Situation 2 : candidate stuck at calculation, but performed well in reasoning and case progression and generating insights.

Hope this helps

best
Benjamin

Antwort auf Frage: Lost in middle of case?

Hey,

Regarding your first point: Try always to think aloud. Explain what information you have so far, what you want to determine and what information is missing, then ask for ths information. This also helps when you get lost. Do a quick synsthesis and link the new information to the objective - is it sufficient to answer the question or do you need more data.

Never skip branches, this seems as if you are not structured. I would suggest you note the interesting fact for yourself or remark that you will look into it in more detail once you finished the branch which you are analysing at the moment.

Hope this helps.

A similar situation is very common in case interviews, and I would suggest the same advice applies:

 - Ask for a minute or two to think through the question. It may feel a little strange but I don't know a firm which will have an issue with you taking this time

 - Secondly, the interviewer is not trying to trick you, so if you start suggesting some reasonable idea's your interviewer may well help steer you. They are not testing your ability to answer an individual question, but far more how you think. The best candidates don't always get the answer right first time

Hope that helps!

Antwort auf Frage: What's the best way to move on from getting stuck in a case interview?

Hey Kay,

Really good answers above (or below?). One important thing to add is that an interviewer evaluates your process more than anything else. He / she is not interested in the answer to the case (they know it already...) but in how you get there. If you get stuck, it's a great moment to display that you have the composure and attributes to get out of the pickle while keeping a professional attire. As such, an interview is a bit like show business - The show must go on!

A great correction or recovery from a case that has gone slightly south is often a great way for the interviewer to get insight in your process. Do well, and you'll be surprised by the results. After all, how good can you evaluate somebody's problem solving ability if during the case performance, they don't run into the slightest little problem themselves. In short - see those moments of friction as an opportunity to display how you deal with challenges in real time!

Hi,

I would say in this case you should demonstrate something else. What can it be? 

  1. Structured approach - try to make a step back and lay out a structured way to find a solution. Even if you can't find it, you can at least do a roadmap. Tip: ask an interviewer if you are going the right way
  2. Creativity - think of alternative solutions / multiple approaches / generate ideas
  3. Visualize - start drawing the details on paper, discussing it with the interviewer. It helps

Antwort auf Frage: How to proceed when I get stuck?

Hey anonymous,

There are two major strategies that can help you in those situations:

  • go back to your framework, evaluate what have you already analzsed and what you're still missing and try to "recompose yourself" from there
  • you should always have on the back of your mind what's the client objective and what should be your final goal with the case, so that you can think what do you need to do in order to have an answer or recommendation for the client (based on his ask)

Hope this can help

Design Thinking
Design Thinking ist mehr als nur ein Ansatz oder eine Methode – es ist eine Denkweise, die Kreativität und Problemlösung in den Mittelpunkt stellt. Um diese Denkweise zu verstehen, betrachten wir die drei wesentlichen Elemente von Design Thinking: People (Menschen), Process (Prozess) und Place (Raum). Diese Elemente bilden das Fundament für die Anwendung von Design Thinking in der Unternehmensberatung.Die Evolution von Design ThinkingUrsprünglich in den kreativen Umgebungen von Designstudios entstanden, begann Design Thinking in den 1960er und 1970er Jahren, sich als Ansatz für kreative Problemlösungen zu etablieren. Rolf Faste, Professor an der Stanford University, prägte den Begriff "Design Thinking" in den 1980er Jahren. Von einem reinen Designansatz hat sich Design Thinking zu einer interdisziplinären Methode entwickelt, die weit über die Grenzen des traditionellen Designs hinausgeht. Unternehmen und Organisationen haben erkannt, dass diese Denkweise nicht nur für die Entwicklung von Produkten, sondern auch für komplexe Systeme, Dienstleistungen, Business Models und soziale Innovationen anwendbar ist.Die drei Elemente von Design Thinking1) People (Menschen): Die Schlüsselrollen der MenschenDer Fokus von Design Thinking liegt auf den Menschen, ihren Bedürfnissen und Perspektiven. Menschen stehen im Mittelpunkt des Entwicklungsprozesses, sei es bei der Gestaltung von Produkten, Dienstleistungen oder Unternehmensstrategien.2) Process (Prozess): Sechs iterative Schritte Verstehen: In diesem ersten Schritt geht es darum, das Problem und die Bedürfnisse der Zielgruppe zu verstehen. Interviews, Beobachtungen und Analysen helfen, einen umfassenden Einblick zu gewinnen.Beobachten: Durch Beobachtungen vor Ort oder die Analyse von Daten können zusätzliche Einblicke gewonnen werden. Dieser Schritt dient dazu, den Kontext des Problems besser zu verstehen.Sichtweise definieren: Basierend auf den Erkenntnissen aus den ersten beiden Schritten wird die Problemstellung neu formuliert. Es geht darum, den Fokus zu schärfen und den eigentlichen Kern des Problems zu identifizieren.Ideen generieren: Kreativität steht im Zentrum dieses Schritts. Durch Brainstorming und kollaborative Ansätze werden zahlreiche Ideen generiert, um das Problem anzugehen.Prototypen erstellen: Ausgewählte Ideen werden in Prototypen umgesetzt. Dies können einfache Modelle, Skizzen oder Simulationen sein, die die Lösungsansätze greifbar machen.Testen und evaluieren: Die Prototypen werden mit der Zielgruppe getestet. Das Feedback fließt zurück in den Entwicklungsprozess, und es erfolgt eine iterative Anpassung der Lösungen.3) Place (Raum): Der Raum für KreativitätDer physische und soziale Raum, in dem Design Thinking stattfindet, spielt ebenfalls eine entscheidende Rolle. Offene und kollaborative Räume fördern den Austausch von Ideen und ermöglichen eine effektive Zusammenarbeit. In speziellen Workshops oder Design-Thinking-Labs kann ein Raum geschaffen werden, der die Kreativität und Innovation fördert.Die wichtigsten Erkenntnisse über Design ThinkingDesign Thinking ist eine kraftvolle Denkweise, die sich in verschiedenen Bereichen erfolgreich etabliert hat. Die Betonung auf People, Process und Place ermöglicht es, kreative Lösungen zu entwickeln, die nicht nur funktional sind, sondern auch die Bedürfnisse der Menschen in den Mittelpunkt stellen. Die iterative Anwendung der sechs Schritte bietet einen strukturierten Weg, um von der Problemstellung zu durchdachten Prototypen und letztendlich zu innovativen Lösungen zu gelangen.
