English used in case interview

As a non-native English speaker applying for McKinsey in a non-native English-speaking country, I'll be doing my case interview in English. While I can speak English fluently, my grammar isn't perfect. Will interviewers be very strict about my grammar, or as long as they understand what I'm saying, will grammar correctness not be a significant concern? Considering they may also be non-native English speakers themselves.

Hi there,

Only if your self-consciousness about your grammar issues impacts your case performance.

Let me explain: You want to use your cognitive abilities to think about the case problems (structure, chart, math, etc.) and not worry about how you come across. The more self-conscious you are about your grammar, the more energy and focus you take away from thinking about what matters and bringing it across confidently.

In short, minor grammar errors are usually not an issue. What counts is 

  • the quality of your content
  • the structure of your communication (not grammar per see)
  • the ability to appear confident and relaxed in a challenging situation

All the best,

Florian

Hi there,

Q: Will interviewers be very strict about my grammar, or as long as they understand what I'm saying, will grammar correctness not be a significant concern?

I would say it really depends on your level. If you are generally fluent and make a small mistake here and there, there should not be issues. On the other hand, if you make multiple mistakes and they require English for the job (I suspect that's why they will interview you in English), that might be an issue.

Good luck!

Hi there,

I would be happy to share my thoughts on your question:

  • First of all, the clarity of your thought process and how effectively you communicate your ideas is more crucial than perfect grammar. As long as your interviewer understands your points, minor grammatical errors typically won't be a significant issue, especially in a non-native English-speaking country.
  • Moreover, practicing your English speaking skills can still be beneficial. Focus on clarity, conciseness, and structuring your thoughts logically rather than on grammatical perfection.
  • Lastly, remember that interviewers are aware of the challenges faced by non-native speakers and usually are more focused on the content of your answers. However, I would advise you to clarify at the beginning of your interview that English is not your first language. This transparency can help set the right expectations and also show your proactive approach to addressing potential challenges.

If you would like a more detailed discussion on how to best prepare for your upcoming interviews, please don't hesitate to contact me directly.

Best,

Hagen

Hi there,

the reason that they conduct the interview in English is because they believe that proficiency in English is a prerequisite to be successful at the job they are hiring for. This is due to the international nature of the role and/or general requirements for client and company internal communication.

You therefore have to demonstrate that you are fluent in English and are able to talk through a business problem (i.e. your case). Individual grammar errors are not a dealbreaker if you have general fluency and are conversational.

Good luck

For consulting firms like MBB, the focus during case interviews is primarily on your problem-solving abilities, analytical skills, and how you structure and communicate your thoughts under pressure. While fluency and clarity in communication are important, interviewers generally understand the fact that candidates may come from diverse linguistic backgrounds, especially in non-native English-speaking countries.

No, don't worry about it. 

There are plenty of McK consultants at various levels of seniority who don't have perfect English. 

As long as you make yourself understood, this shouldn't be a problem. 

What you should focus on, because it makes a huge difference, is to speak slower. That will make you easier to understand and also help project more confidence. 

Best,
Cristian

They do not need perfect grammar.

As long as you can communicate clearly, explain your thinking and understand everything they say/give to you, you will be just fine!

Hi there,

I will not worry too much about English as long as they can understand you. Having said that, I would suggest to get yourself familiarised with the most commonly used business terms in English. Thank you and best of luck.

 

Regards,

David
