Getting an interview with Y Combinator (YC) is a dream milestone for countless founders worldwide. YC has funded over 4,000 startups, including legendary names like Airbnb, Razorpay, Stripe, Groww, Zepto and Reddit. Collectively, YC alumni are now worth over $1 trillion. But before you experience YC, you must pass the interview.
You’ve got 10 minutes, a room full of sharp minds, and the chance to prove why your startup is the next big thing. No pressure, right? But don’t worry! Here’s a guide with tips and relatable advice to help you crush it.
This article draws inspiration from real-life advice shared by Aseem Gupta, co-founder of SuperKalam, who successfully got into Y Combinator's Winter 2023 batch.
YC Interview: What to Expect?
YC’s 10-minute interview is legendary for its intensity. The partners ask rapid-fire questions to gauge your understanding of your business, market, and execution plan. They value clarity, confidence, and authenticity over buzzwords or rehearsed pitches.
Aseem emphasises that YC isn’t just investing in your idea but in you. They’re looking for founders who:
Understand the Market: Know your users, their pain points, and how to reach them.
Have Grit: Show willingness to pivot when needed.
Think Big: Your idea doesn’t need to be perfect, but it should have the potential to scale.
"YC doesn’t expect you to have all the answers yet. What they care about is whether you have the drive and clarity to find them."
8 Must-Know Tips for a Successful YC Interview
Understand Your Startup Like It’s Your Best Friend
Ever been asked about your best friend and answered effortlessly? That’s the level of comfort you need when explaining your startup. YC interviewers will cut straight to the heart of your business with questions like:
What problem are you solving?
Who is your customer?
Why is this the right time for your startup?
In short, if someone woke you up at 3 AM, could you explain your business without stumbling? If not, it’s time to refine your pitch. Avoid jargon. Focus on simplicity and clarity.
Pro Tip: Practice with friends or family who know nothing about your industry. If they get it, you’re on the right track.
Less is More- Practice Brevity
YC interviews are famously brief—usually about 10 minutes. This means you need to deliver high-impact answers without rambling. Focus on the “why” and “how,” leaving out unnecessary details.
Nervous energy often makes people rush—resist this urge.
Trick: Practice answering common YC questions in under 30 seconds. Keep your responses sharp and to the point.
Highlight Real Progress (Even if It’s Small)
YC loves traction—it shows that you’ve moved beyond ideas to execution. Don’t worry if you don’t have millions in revenue yet. Highlight anything that shows momentum:
Revenue Growth: Even small numbers matter if they’re growing.
User Base: If you’re pre-revenue, showcase active users, signups, or engagement.
Waitlists: Have thousands of people eager to try your product? That’s traction!
Example: “We launched two months ago and already have 1,500 active users with a 30% month-over-month growth.”
Show Why You’re the One to Solve This Problem
YC invests in founders, not just ideas. Your passion and expertise matter just as much as your metrics.
Did you struggle with this problem personally?
Do you have unique skills or insights others don’t?
Example: If you’re building an AI-powered tool for small businesses and you’ve spent 10 years consulting with SMBs, YC will see the connection. They want to back founders who are obsessed with their problems and deeply understand their space.
Be Honest About Unknowns
If a question stumps you, resist the temptation to bluff. Instead, acknowledge it: “That’s an interesting question. I’d need to check the data and follow up afterwards.”
YC values honesty and self-awareness. If there’s a challenge in your business, acknowledge it openly and discuss how you plan to overcome it.
Know Each Other as Co-Founders
If you’re part of a founding team, YC may ask questions to understand your dynamic. They want to see if you complement each other and can handle stress together. Misaligned answers are red flags.
Take the time to discuss these key points as a team:
Why are you working together?
How do you handle disagreements?
What’s the long-term vision for the company?
They should not just know each other, but the same dynamics should be evident during the interview. For multi-founder interviews, each founder should join from a separate laptop, ensuring their names appear on the video call screen.
Rehearse your introductions.
Designate a lead speaker (ideally the CEO) to manage the conversation flow. However, all founders should contribute during the interview.
Pro Tip: Encourage smooth handoffs. For example, say, “Rohit, do you want to add to this?” This not only keeps the conversation dynamic but also showcases teamwork.
Perfect Your Tech Setup
A smooth and professional video setup goes a long way in making a positive impression. Here are a few key things to check off your list:
Check Your Video Setup: Test your camera, microphone, and video conferencing platform multiple times before the interview.
Lighting: Choose a well-lit room; natural light works wonders. Avoid backlighting, which can cast shadows on your face.
Internet Connection: High-speed internet is non-negotiable. Test your connectivity and have a backup option ready.
Answer With High Clarity
Listen carefully to each question and ensure your answers are concise and precise. Vagueness or overloading with unnecessary details will only waste precious time. If you don’t understand a question, asking for clarification is perfectly fine.
Tip: Before you wrap up, leave them with something they’ll remember—an insight into your market, customers, or industry. Think of this as your mic-drop moment.
Few Basic Questions to Prepare For
YC interviewers will test you, and it might feel a bit like a rapid-fire round on a game show. They’ll dig into your assumptions to see how well you’ve thought through your business.
Some founders freeze when asked, “What if your primary growth channel stops working?” But remember, they’re not trying to tear you down—they want to know if you can adapt.
YC interviews often revolve around these foundational questions. Here’s how to tackle them:
1. How did the founders meet?
This is the question where you can show the chemistry and complementary strengths between the founders. YC wants to know if you trust each other, understand each other's strengths, and have a shared vision.
Tip: Keep it brief but personal.
2. What stage is your startup at?
YC partners will likely know your stage from your application, but they’ll want to hear about your progress since then. Show that you’re making tangible strides toward growth.
Example Answer:
“Since submitting our application, we’ve completed our MVP and onboarded 50 beta users. We’ve also secured two pilot contracts, one with a mid-size retailer and another with a direct-to-consumer brand. We’re in a strong position to scale and are excited to bring on more customers over the next few months.”
Tip: Be specific about your achievements. Use hard numbers wherever possible to show real progress.
3. What are your customer numbers?
At this point, YC is looking for solid evidence that your product resonates with users. They want to know if you're gaining traction and, ideally, whether users are willing to pay for what you're offering.
What to say:
“We’ve onboarded 1,000 users so far, with a 20% conversion rate to paid plans, generating $5,000 in monthly recurring revenue (MRR). Our user acquisition cost is $30, and our lifetime value per user is $300.”
Tip: Be precise with your numbers. YC loves hard data. Even if you’re in the early stages and don’t have paid users yet, make sure you’re ready to talk about the feedback and user engagement you’ve received.
4. How will you acquire your first customers?
This question is about showing that you’ve thought through your growth strategy. YC wants to know how you plan to get your first customers—and your answer needs to demonstrate that you have a clear, step-by-step plan for reaching them.
Example: “In the next 6 months, we plan to scale up by partnering with tech conferences to showcase our solution while running targeted ads on developer platforms like GitHub and Stack Overflow. We’ve already had positive feedback from early users who are eager to integrate our solution into their workflow.”
5. How big is your market?
YC will ask you about your Total Addressable Market (TAM) to determine whether there’s room for growth. You need to show that the opportunity is big enough to scale, but don’t get caught up in inflated numbers.
Tip: Use credible, well-researched data to support your market size and growth projections. Be realistic and back up your market size with credible sources.
These questions may seem basic, but how you answer them can make or break your YC interview. YC is looking for founders who can think on their feet, clearly articulate their vision, and show that they’re ready to take on a big challenge.
Final Words
YC alumni often say the experience changes everything. It’s not just the funding or the fame; it’s the confidence and clarity YC brings. Founders leave the program with a clearer vision, stronger execution plans, and a network that’s impossible to match!
