What the test asks

  • Read a confidential information presentation on a family-owned supplier of premium abrasives, chemicals and tooling for metalworking.
  • Write a memo for the investment committee. Two pages at most.
  • Four required sections: an investment thesis with what you would do after closing, highlights in order of importance, risks and mitigants in order of importance, and a recommendation with a price.
  • No model is asked for. You will want one.
  • Be ready to defend the recommendation afterwards.
  • All of it in 48 hours.

What the answer looks like

The answer key is my corrected working model, with a note on each corrected row. You can check yours against it line by line. This example is from the free test, so nothing here gives this case away.

The note on the Taxes row

<- Got this wrong on the day: in the 60-minute file (row 27) this was EBT x (1 - tax rate), which is after-tax income, and cash taxes read it. Tax is EBT x the tax rate.

The story

In May 2023 I was interviewing for an associate role at a private equity firm, in a process that ran through a recruiter. After a first round, the firm invited me to the next one, a written case study.

The recruiter emailed it on a Sunday morning: a one-page prompt and a presentation on a company for sale. I had 48 hours, around a full-time job, to write a memo for the firm's investment committee, two pages at most. Nobody asked for a model. I built one anyway to get to a price.

I sent the memo a few hours before the deadline.

Before you start

Is this the real test?

It is recreated from the test I took. The format, the task and the time limit are the same. The company is fictional and its figures are changed.

Why two models?

One is my working file. The other is the same file corrected, with a grey note on every row that changed. Check your numbers against the corrected one.

Did the corrections matter?

Yes. The model had no tax line and charged less interest than the memo said. Fixing both, and holding for the five years the memo states, takes the base case from 21.6% to 16.9%. The debrief lists each fix with its cells and what it was worth.
