Private equity interview card of the day

9 November 2026 · LBO Mechanics and Paper LBOs

The interviewer asks

How do you split four minutes on a paper LBO, and what accuracy is acceptable?

Say your answer out loud first, then open the model answer.

Show the model answer

Roughly one minute to set up, two minutes to run the five years, and one minute to read the result. I work to about two significant figures and accept an answer within about 5 percent. I talk through each line as I write it, so the interviewer can follow, and I leave time at the end for a sanity check rather than polishing the arithmetic.

What the interviewer listens for

  • One minute set up, two run, one read
  • Within about 5 percent is fine
  • Talk through each line

LBO Mechanics and Paper LBOs · INT.LB.4.a: Build a paper LBO and read off the IRR in under four minutes using rounding, a one-page set-up and sanity checks.
