9h case study test for MM PE internship

MBA candidate here with ~3 years pre-MBA MBB consulting experience and BBA. I’ve been shortlisted for a summer internship with a Tier 2-3 MM PE firm and asked to complete a 9-hour take-home case study.

Some questions below. Any insights will be much appreciated. 

  1. Is 9h test standard these days for MM PE internship recruiting, or a red flag? I’ve read older forum threads and people's views seem mixed about firms that require such long duration tests...
  2. Is it reasonable to ask the firm what the test will broadly entail, or is that usually frowned upon? Past forum threads suggest a test this long seems likely to involve a fuller LBO model plus some investment memo or deck output, but more clarity may help me prep more efficiently.
  3. What level of modeling depth should I expect? For example, if they do not specify, would candidates typically build a full 3-statement + pro forma balance sheet, or is a cleaner operating model + debt schedule + returns + sensitivity analysis usually sufficient?
  4. Do candidates usually prepare generic model / memo / deck templates in advance?
  5. With 4 days left, how best to prioritize prep? I have some modeling experience from consulting and have gone through WSP's LBO course, but am still struggling to build the model from scratch within short duration.

1 - I’ve done ~5–6 model tests / case studies during PE recruiting. Most were 3–4hr LBOs with a few short-answer questions. I’ve also had a 24hr take-home with a full LBO and a more complex case background / set of questions. So 9 hours does feel a bit unusual because it sits in the middle, but I wouldn’t view it as an immediate red flag by itself.

2 - Asking about the scope is completely fine IMO. In my experience, some HR / recruiters will simply say they can’t disclose anything, while others may give you a high-level idea, e.g. “it will be an LBO of a public company.” I don’t think it hurts to ask, as long as you frame it as wanting to allocate your time appropriately rather than asking for hints.

3 - If it’s a 9-hour case, my guess is they expect a fairly complete LBO model, though the balance sheet can probably be lighter. I reviewed a few model tests for my previous firm and my personal thought is that 1) make sure the model is highly readable, so formatting actually matters a lot; 2) formulas are clean and linked, with hardcodes limited to clearly marked input assumptions; and 3) the entry / exit assumptions and operating assumptions are reasonable and defensible.

4 - Yes. For a take-home case, I think it’s standard to have clean model / memo / deck templates or shells ready. 

5 - Modeling for the purpose of beating a model test is a lot like practicing a sport or instrument — a big part of it is muscle memory. With 4 days left, I’d focus less on learning every possible advanced modeling feature and more on doing timed reps.
