Case room, three questions. “Profits at a regional airline fell twenty percent. Draw me a diagram of the drivers.” The drivers drawn in the Diagram pane. “Estimate the market for e-scooter rides in Germany.” Sized step by step in the Math pane. “What's your recommendation, in thirty seconds?” The recommendation, ready to say. Shift+Left walks back to the first question.
Product room, three questions. “Our north-star metric dropped fifteen percent week over week. Walk me through it.” A Short Answer, with the checks as a table in Technical Details. “Estimate the weekday rides in a city of eight million.” Worked in the Math pane. “Tell me about a time you influenced without authority.” A story from the candidate’s own resume. Shift+Left walks back to the first question.
Finance room, four questions back to back. “Walk me through a DCF.” “Depreciation goes up by ten. Walk me through the three statements.” The three statements as a table. “Ballpark the WACC: sixty percent equity at twelve, debt at six pre-tax, tax twenty-five.” The formula carried to a number in the Math pane. “What's the difference between enterprise value and equity value?” Each question keeps its own card. Shift+Left walks back to the first question.
Fundraising room, three questions. “Walk me through your unit economics.” Answered from the founder’s own notes. “Estimate the dilution if you raise twelve at forty-eight pre.” Worked in the Math pane. “What's your CAC payback again?” The same figure as the first time. Shift+Left walks back to the first question.
Data science room, three questions. “Estimate the sample size to detect a one-point retention lift.” A Short Answer, then the Math pane. “Write a SQL query: top three products per category.” SQL in the Code pane, a comment on every line. “Explain the bias-variance trade-off to a product manager.” Plain English, then the equation in the Math pane. Shift+Left walks back to the first question.
Engineering room, one round, five questions. “Tell me about a time something went wrong on a project you owned.” A story from the candidate’s own resume. “How would you architect a link shortener?” System Design Clarifying Questions above the Short Answer, then the Diagram. “You mentioned the edge cache. What if one link goes viral?” Built on what the candidate had just said. “Write a function that merges overlapping intervals.” The approach to say, then Code with a comment on every line. “Rough numbers — how much storage for a billion links?” Worked in the Math pane. Shift+Left walks back to the first question.
