How to Prepare for the Y Combinator Interview
Zen99 went through Y Combinator in S’14, so I thought I’d share my tips on how to prepare.
Philosophical Advice
I’m starting with these because they are more important than the tactical advice below. These are also applicable to the YC application, and fundraising in general.
1. Draw the conversation toward your strengths
I think YC cares primarily about three things:
#1: A strong founding team
Statistically, most companies going through YC are going to fail. Many will pivot. All will have at least some iteration on the product. Each change is hard work and emotionally draining. You’ll want to have someone by your side who isn’t going to leave when the going gets tough. YC wants that too, because it increases your chances of survival.
If you and your co-founder(s) have a strong relationship, emphasize it. Particularly if you’ve worked together before, and even more so if it was something with traction/success.
(For us, my cofounder and I met in Sigma Chi during college, were close friends who had traveled together, etc.)
#2: Big potential market opportunity
This doesn’t mean “we’re a consumer product, so our potential market is every human on earth.” It means you’re riding some wave bigger than yourself.
(For us, it was a change in the labor market towards more “contract/flexible work”, and away from “employee/only one company” work.)
#3: Having relevant experience to execute on the opportunity
Ideas can be easy; but execution is always difficult. Execution is easier if you understand the industry, which normally comes from working in it. That’s also why I’d argue second-time founders are appealing — they’ve already made all the first time founder mistakes (which will happen, regardless of how much great advice you get).
(For us, it was me having my CPA and overseeing a workforce of contractors at Exec, and my cofounder’s experience with building web-based products.)
2. Traction trumps all
Those three points are less important if you can demonstrate traction. Being able to demonstrate you’re making something people want (and ideally are paying for) is the most important thing you can do.
A side note here: your 20 friends on the beta should not be equated with “something people want.” They probably want to be a good friend more than they want the product.
(For us, we applied at the idea stage, so we emphasized the three points above.)
3. Be a nice person
Working with mean people sucks. YC doesn’t have to work with them, and won’t.
It’s relatively easy to pick up on someone’s personality in their application. It’s even easier during the interview; most people make judgments within milliseconds. If you’re not a nice person, don’t try to fake it. Compensate for it by having such a good business that they can’t say no. (But do try to become a nicer person — life is too short to be mean.)
4. Remember YC doesn’t guarantee success
The YC brand and community are phenomenally powerful and valuable. But just like fundraising, it’s an enabler and not an end. Its main purpose is to get you one step closer to building a great business.
YC is not necessary for success. Most successful and happy people didn’t go to college, or went to unknown schools. Stanford or Harvard may make the first step easier, but ultimately your drive and core values are what make you successful.
5. There are no secrets or hacks
Everyone hopes for a silver bullet that fixes everything. The only secret you should know is that even though you expect a startup to be hard, it’s still 100x harder than that.
Startups are an emotional rollercoaster: the highest highs and lowest lows, alternating on a nearly daily basis. They often negatively affect your social life, personal relationships, and physical wellness, regardless of how hard you try not to let them. Those who win have hustled, and hustled hard. Prove you’ve done this and will keep doing it, and you’ll gain YC’s respect.
Tactical Advice
Once you’ve figured out the above, then you can start practicing these:
1. Prepare, and be brief
Think up a ton of questions you might get asked, then write out responses. Then cut down all of those responses to one (at most two) sentences so you know how to answer succinctly. Don’t talk for the sake of talking — they will have plenty of questions to fill the 10 minutes.
2. Get an alum to mock interview you
If you have a friend who has gone through the program, ask if they’ll interview you. They’ve been through it, and so are going to be much better about simulating what the interview is actually like. Plus it helps get you more comfortable with talking about your idea. If you can’t find anyone, watch office hours from Startup School to get a sense.
3. Don’t be deterred by interruptions
Don’t be surprised if you’re interrupted mid sentence, particularly if you’ve been talking for more than 10 seconds. It’s not meant to be rude — it probably means you’re not being concise enough. If anything, it’ll help you get back on track to questions that matter.
4. Don’t waste time
10 minutes is a very short time. When you walk in, give a brief handshake and introduce yourself. But don’t waste any time on other formalities, just get right into it.
5. Don’t be deterred by directness
Naturally some partners are just more direct than others — which can come off harsh if you aren’t used to it. Don’t let it phase you.
6. Don’t worry about all founders talking
I talked the majority of the time during our interview. That’s not good or bad — it will depend on your situation. We were an early stage idea and I knew more about the space given my background.
They will likely ask you who is CEO though — they did for us. It’s probably ideal for the CEO to to play quarterback, and pass questions to the correct person if it’s not their area.
7. Have a demo ready, but don’t expect to use it
Have one pulled up and prepared (that is, have your laptop open and on the pages you would want to show to eliminate any load time). But don’t be surprised if they don’t ask to see it; they didn’t for us.

- [Update Dec 2020] Paul Graham has written an essay addressing (among other things) advice for YC interviews; it’s a must read. YC also has tips on their website, and Michael Seibel has tweeted his. These are all guaranteed to be far more helpful than my blog post, so don’t skip them.
- You’ll notice I linked to several of Paul Graham’s essays; that’s because you should read all of them.
- Chas from Aptible (S’14) put together a great list of potential YC interview questions, and so has Brad from Perfect Audience (S’11).
- There are also some good answers (including from Y Combinator partner Paul Buchheit) in this Quora thread.
I didn’t apply by the deadline — should I still try applying?
Yes! They generally accept companies up until the program starts. You’re probably more likely to be considered if you follow the deadlines, but they are also committed to finding the best and brightest companies. If you can’t submit an application, figure out another way to get in front of them.
