Frequently asked questions

What questions does YC ask in interviews?
YC interviews cover: What does your product do? Who is it for? How does it make money? Why is now the right time? What's your competitive moat? How fast are you growing? Why are you the right team? The simulator covers all of these and 30+ more.
How long is a real YC interview?
YC interviews are 10 minutes long. They move fast. Partners ask follow-up questions the moment an answer lacks specificity. This simulator replicates that pacing.
Does this guarantee getting into YC?
No. YC acceptance depends on many factors beyond interview preparation. But preparation dramatically improves how clearly you articulate your thesis — which matters both in the YC interview and in every VC meeting you take.
Can I use this for non-YC investor meetings?
Yes. YC interview questions are a superset of what most early-stage investors ask. Practicing for YC prepares you for almost any seed or Series A conversation.
Is this free?
The basic YC practice session is free and doesn't require signup. Unlimited sessions and detailed scoring are available with a HeyMojo account.
