Hi everyone,
I am applying to McKinsey's Madrid office, and in preparation for the eventual interviews, I was wondering about the interview language. I have already lurked around the Q&A section and the official website, and I understand that the interviews will likely/mostly be carried out in the local language (i.e., Spanish in my case), which is not a problem in and of itself.
My question is: during a case, is it okay if I use business-English terminology (e.g., Revenue in place of Ingresos or Penetration Rate in place of Tasa de Penetración) instead of their Spanish equivalent?
I ask because I literally never had to use (nor work with) such words in Spanish, and I don't know whether it makes sense to learn all the business-English terminology in Spanish.
I look forward to hearing your insights, and thanks a lot in advance for the help!
