Hi there,

Unfortunately, I don't have any first- or second-hand insights on the Efficio MS Excel exercise. However, I would be happy to share some general information that might be useful for you:

  • The exercise likely involves working with data in MS Excel and using functions and formulas to solve a business problem.
  • For your preparation, I would advise you to practice using MS Excel functions and formulas, such as the INDEX/ MATCH combination, pivot tables, and conditional formatting. Additionally, I would advise you to familiarize yourself with basic data analysis concepts like data cleaning and preparation.
  • When approaching the exercise, I would advise you to take your time to understand the problem and the data at hand. After this, think about the best approach to solve the problem and make sure to check your results and test your solution.
  • Lastly, I would also advise you to brush up on your communication and presentation skills, as you may be required to explain your approach and results to the interviewer.

If you would like a more detailed discussion on how to best improve your MS Excel skills for this exercise, please don't hesitate to contact me directly.

Hi there,

Unfortunately I don't know much about Efficio (imagine that, a coach confessing ignorance!), but a quick google led me to understand the following from their interviews:

  • An online numeracy and problem-solving test
  • A first round of interviews, typically involving two interviews and a case study
  • An Excel-based case study
  • A second round of interviews with senior management

I actually do have a few excel-based real-life case studies (from past candidates). They are across the topics of food delivery, investment decisions, and mining/operations optimization.

Feel free to reach out and I can take you through them!
