Free cofounder prep

YC interview question drill

Six private prompts for the short, candid conversation YC actually runs. Work through the facts with your cofounders in ten minutes—without preparing a pitch deck, script, or stored answer.

Private by design: this drill never asks for or stores your answers.

Six questions. Ten focused minutes.

YC interviews are conversations, not presentations. Work through one prompt at a time, then use the summary to decide what still needs evidence or a sharper answer.

Prepare evidence, not a performance

The best preparation is knowing what has changed, the numbers that matter, what you have learned, and what a partner can see in the product.

Use the official source

YC says interviews are ten-minute Zoom conversations and expects every founder to participate. Its guidance—not this independent tool—remains the source of truth.

Frequently asked questions

What questions does YC ask in an interview?

YC interviews are short conversations, so founders should be ready to describe the company plainly, explain current progress and metrics, discuss obstacles candidly, and show what they built when asked. Exact questions vary by company and interviewer.

Should founders rehearse a YC interview?

YC advises founders not to prepare a presentation or a script. This drill is a short way to identify the evidence and facts each founder should know, then have a natural conversation.

Does this YC interview question drill save our answers?

No. The drill does not collect a text answer, metric, company name, or application content. A cofounder-share link carries only campaign attribution and no founder answers.
