Modelling Test
A timed technical exercise, usually 1-3 hours, in which a candidate builds a financial model (LBO, DCF, or merger model) from a data set or set of assumptions, under interview conditions with no internet access.
Why Modelling Test matters in interviews
The modelling test is where private equity processes eliminate most remaining candidates, and it fails people on execution rather than knowledge. Knowing the format and the marking criteria in advance is most of the preparation.
How it works in practice
Formats range from a 60-90 minute timed LBO from a blank sheet, through a three-hour test with a provided template, to a full-day or take-home case with a written investment recommendation.
Marking weights accuracy of the mechanics (sources and uses, debt schedule, circularity handled, returns calculation) alongside presentation and the quality of the conclusion. A model that balances and produces a defensible recommendation beats a more elaborate one that breaks.
The standard build sequence: transaction assumptions, sources and uses, opening balance sheet adjustments, operating projections, debt schedule with a cash sweep, returns waterfall, then sensitivities on entry and exit multiple and leverage.
What candidates get wrong
- Spending too long on the operating build and running out of time before the returns calculation — the only part that answers the question asked.
- Leaving the model unformatted. Blue inputs, black formulas, clear labelling: reviewers judge it as a work product.
- Not stating a recommendation. Most tests ask what you would do; a model with no conclusion scores poorly regardless of accuracy.
- Building from scratch under time pressure without having practised the same sequence repeatedly beforehand.
Modelling Test: frequently asked questions
How long is a private equity modelling test?
Commonly 60-90 minutes for a timed LBO built from a blank sheet, two to three hours where a template is provided, or a full day to several days for a take-home case with a written recommendation. The shorter the test, the more it rewards a rehearsed build sequence.
What do private equity firms actually mark in a modelling test?
Whether the mechanics are right — sources and uses tie, the debt schedule and cash sweep work, returns are calculated correctly — plus formatting and clarity, and above all whether you reach and defend a clear investment recommendation. A clean, complete model with a stated view beats a sophisticated one that does not resolve.
