Brian · your case coach
You tried it first — now let's compare the decision logic, not the wording. Open note 2.
The strong answer — walked through, note by note
I would treat this as a go-or-no-go decision first… 2Second, does SproutBite have a right to win — product fit, brand credibility, channel access? Third, do the economics clear the 12-month hurdle…
2Why this worksIt's a test, not a topic — a branch that tells you what evidence to seek, and could flip the answer to no.
BBrian's read on your attempt
What I saw: your second branch names a topic — “competition” — not a test.
Try this: ask it as a decision question: can SproutBite win against the three incumbents?

Verdict
“You were structured and commercially sensible, but your case leadership and communication were only solid, not standout — you left value on the table by not pressure-testing the launch.”

Strong
Evidence from your call
“I'd structure my analysis around four buckets: market attractiveness, competitive dynamics, internal capabilities, and the financial case.”
“I'd start with market sizing, because if the segment is too small, nothing else matters.”
What went well
- You tailored the structure to the case instead of reciting a generic framework.
- You named the branches clearly and separated external and internal drivers.
What to fix
- Your branches slightly overlap between market attractiveness and the financial case. Tighten the logic.
- Be explicit about how the branches combine into a final yes/no.
Hypothesis-Driven
You stated a concrete, testable launch hypothesis at 01:00 and used it to guide the case.

Case Leadership
You moved the case forward, but were still somewhat interviewer-led and could have driven the analysis more aggressively.

Developing
Evidence from your call
“Should I look at the cost side next, or would you rather I size the market first?”
“Okay, sure. I can go there if that's more useful.”
What went well
- You never stalled when handed a new exhibit and kept the case moving.
- You summarized where you were before moving to the next branch.
What to fix
- At 06:20 you asked the interviewer which way to go. State your plan and proceed instead.
- Own the next step: name the question you're answering and the data you need to answer it.

You drew a clear implication from the math and ended with a sensible launch recommendation, not just a summary of facts.

Evidence from your call
“So if we walk through the numbers... the market's about 40 million... which means margins work... so I'd probably say launch.”
What went well
- Your recommendation was unambiguous once you reached it.
- You backed it with quantified reasons, not vague intuition.
What to fix
- Lead with the answer, then three short reasons. Your close built up to the recommendation instead of opening with it.
- Move the calculation recap out of the synthesis; save it for the follow-up.
Professionalism
You stayed calm, collaborative, and appropriately assertive when challenged.

Across your feedbackYour structure needs a clearer decision roadmap
3 of 4 casesYou build reasonable issue trees, but you do not consistently turn them into a ranked testing plan tied to the client's decision.
You are not leading the case enough after the setup
4 of 4 casesFeedback repeatedly says you wait for interviewer direction instead of proposing the next analysis or test yourself.
Your synthesis comes too late in the conversation
4 of 4 casesYou can interpret results, but you tend to explain mechanics before stating the implication, which weakens recommendation quality.
02Practice cues
Behavior focusLead every update with the business implication
Your repeated top-down and synthesis feedback makes this a good next full case to practice leading with the answer before walking through drivers.
Convert each structure into a ranked testing plan
You need more reps turning a broad profitability tree into a prioritized driver test, not just listing revenue and cost branches.
Propose the next test before being prompted
Before each analysis, say what you want to test, why it matters, and what decision it will unlock. This targets the repeated case leadership gap.
