Efficio - excel-based case study

Hello,

I have an interview with Efficio, which includes an excel-based case study. Does it require any preparation? And does anyone have sample tests to share?

Appreciate a quick response.

Best,

Hi there,

The answer for any interview in regards to “should I prepare” is yes :)

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!

Greetings Ian,
I would appreciate if you can share those Excel mock tests with me, as I have an upcoming excel test for a consultant position as well in the procurement and SCM consulting.
Thanks,
Ian

Hi there,

I actually took and passed that test. However that was several years ago (feeling old;)) so it may have changed in the meantime. At the time, if you were familiar with the main Excel formulas you definitely had an advantage.

Given Ian has some resources, I would recommend to reach out to him as preparing with something similar would definitely help.

Best,

Francesco

Hello!

I haven´t taken it myself, but I have seen mocks and you benefit from knowing the classical formulas. Any basic Excel course can gives you some background, but the key in Excel is to have a lot of practice so you can be very quick. 

Hope it helps!

Cheers, 

Clara

I have an excel-based case, but it's not related to procurement. I would guess that something related to procurement would be more appropriate in your situation. I believe Ian is your best option here.

Hi! 

Did you ever take that test? I am looking to get some insight on what to expect.
