Wharton Moelis Group Case Interview: What the TBD Actually Looks Like
You got the interview invite. You Googled the TBD. You found a lot of generic advice about "collaborative leadership" and "not dominating." None of it told you what actually happens in the room, who is watching, or what the rubric says.
This article does. The format details and rubric below come from a Wharton insider and from coaching calls with students who have gone through the Moelis process. If you want the general prep framework, the companion article How to Prepare for the Wharton Moelis Team-Based Discussion covers that. This piece goes deeper on what the format actually looks like and why generic prep mostly misses the point.
TL;DR: The TBD rubric has five dimensions. You already know them. The problem is that every other candidate in the room knows them too, and everyone is performing the same behaviors. Standing out requires understanding the dynamic, not just the rubric.
The Format, Step by Step
The Moelis TBD puts four candidates in a session with one moderator. That moderator is not there to facilitate. They observe and score.
A day before the session, you receive the prompt. The topic is not a business case. It is a broad, open-ended question. A real example from a Moelis session: how to make buildings more sustainable. No financial model, no market sizing, no industry expertise required. That is intentional.
The session runs 30 minutes. The group is expected to work through the problem, reach some form of recommendation or framework, and show how they function as a team. After the group portion, there is a brief individual debrief. That debrief matters more than most candidates expect.
One thing worth noting: the prompt is given in advance, but you cannot really use the prep time to win on content. Everyone will show up with similar research and similar frameworks. The prep time is most useful for deciding how you want to show up behaviorally, not substantively.
The Rubric (Confirmed)
The moderator is scoring five things. These come from an insider account of the Moelis process, and they map closely to what Wharton's admissions team has described publicly.
1. Do you include others? Are you pulling quieter participants into the conversation? Do you notice when someone is being talked over? A candidate who says "I want to make sure we hear from everyone before we move on" is signaling something that goes beyond content contribution.
2. Do you lead with respect? How you disagree matters as much as whether you disagree. Framing a pushback as a question signals more leadership maturity than correcting someone directly. "Have we thought about the cost implications of that?" lands better than "That doesn't account for the cost side."
3. Do you overly dominate? This is the most common failure mode. Candidates who prepare a lot tend to use too much airtime. The moderator is specifically watching for this. Talking for 40 percent of the session is not a display of leadership. It reads as insecurity or poor calibration.
4. Critical thinking Are you advancing the group's thinking or just contributing volume? The moderator is watching for moments where a candidate's contribution actually changes the direction of the discussion. Synthesis is worth more than new ideas. If you can say "here's where we've landed and here's the gap we still need to resolve," that is critical thinking made visible.
5. How you organize tasks and delegate Can you help the group structure its work, not just participate in it? Someone who proposes how the group should approach the problem, and does it without taking over, is demonstrating a real skill. This is distinct from domination. The difference is whether your structure serves the group or centers yourself.
The Performative Collaboration Problem
Here is the thing no one says out loud: everyone in the TBD knows the rubric. Or a version of it. So what happens is that every candidate shows up doing the same performance.
"That's a great point, Sarah. What do you think, Marcus?" Eye contact. Nodding. Inclusive gestures. Asking rhetorical questions that signal listening. It is a room full of people doing the same imitation of a collaborative leader.
The result is a session that feels artificial. Everyone is performing. The moderator has seen this performance dozens of times. What cuts through is genuineness, which is hard to fake and even harder to prep for directly.
The specific trap is hollow affirmation. Saying "great point" before every contribution you build on is a tell. It reads as a trained behavior. So does asking someone's opinion immediately after you've made a strong point, as a way of appearing inclusive while still controlling the conversation. The moderator is attuned to this.
The question to ask yourself in preparation is not "what behaviors should I display?" It is "what kind of participant do I actually want to be in this group?" The candidates who stand out are the ones whose behavior looks like they are genuinely trying to solve the problem together, not auditioning to solve it.
What You Can Actually Prep
You cannot prep the content. You can prep the behavior. The distinction matters.
Know your one structural move. When groups get scattered, the most valuable thing a participant can do is name where the group is and what it needs to decide next. Practice this sentence structure: "Let me try to summarize where we are. We've covered X and Y. The main thing we still need to resolve is Z." Do that once in a real conversation before the TBD. It will feel less awkward when it counts.
Decide in advance how much you will talk. Most candidates do not have a number in their head. They just talk when they have something to say. The problem is that in a 30-minute session with four people, even speaking proportionally means about 7 minutes of airtime. Set a rough budget. If you feel like you've been talking a lot, you probably have.
Practice noticing the room. The skill of noticing that someone hasn't spoken in five minutes, and doing something about it, is a real skill. It does not come naturally under pressure. Do a practice session with friends and assign one person the job of staying quiet for the first ten minutes. See if you notice. See if you do something.
Reread your essays the night before. The individual debrief will connect back to your application. That is covered in the next section. But your essays are the other half of the TBD, even when you are in the group portion.

The Individual Debrief: It Is Not Just About the Case
After the 30-minute group session, you have a short one-on-one conversation with a member of the admissions team. Most candidates treat this as a TBD debrief. That is a mistake.
The individual conversation can and does go into your essays. The admissions reader in the room has read your application. They know what you wrote about your goals, your leadership experiences, your reasons for choosing Wharton. The debrief is partly a check: does the person in this conversation match the person in the application?
This means you need your narrative integrated, not compartmentalized. If you wrote an essay about building a company someday, and the TBD prompt touched on organizational structure or resource allocation, expect a question that connects those two things. Not because the moderator is trying to trick you, but because they are genuinely trying to understand whether the essay was real.
One more thing: the prompt for the Moelis TBD is often not Wharton-specific or even business-specific. Sustainability for buildings. Urban planning. Public health. The topics are chosen to be accessible, not to test industry knowledge. That is by design. If the prompt feels generic, it is because the content of your answer is not the point.
Action Steps
- Run one practice TBD session this week with 3-4 people on any open-ended topic. Debrief specifically on airtime distribution, not just content quality.
- Practice the synthesis move out loud: "Here's where we are. Here's what we still need to decide." Do this five times in low-stakes conversations before the session.
- Decide your rough airtime budget before you walk into the TBD. Something like: I will aim to speak 4-5 times, contribute meaningfully twice, pull someone in once, and synthesize once.
- Reread your Moelis essays the night before. Know which essay themes are most likely to come up in the individual debrief.
