So, you're lucky enough to have received an interview from YCombinator. Congratulations - you're a good hacker and now you get a free trip to Mountain View or Boston.

It's not a job interview

This is definitely not like a job interview. You won't be wearing a suit and neither will they. Nobody has arranged the chairs to make sure you feel inferior. Don't worry about whether your posture is at the right angle to indicate "interest" but not "aggression". This interview is about more important things, such as:

Passion for the idea

Passion is contagious. When someone truly cares about something and puts themselves on the line for it people always take notice. Taylor Hicks won American Idol. QED

Make sure you have an idea you really care about. Don't try to fake it - if you're not actually passionate about your idea then come up with a new one. Quickly. Your idea should show up in your sleep. I have actually had dreams where parts were on slides in bullet points. I wish I was kidding.

Be flexible

That said - don't mistake passion for stubbornness. You should be as excited about your idea as possible without being violently attached to it. If you're passionate about a bad idea it's probably because there's some really good morsels in there. YC will help you pick out the good parts.

Whenever somebody says your idea has something wrong with it, they are giving you a chance to learn something. The right answer is always "why do you think that?" instead of "we'll prove you wrong".

(Re-)Re-Read the application

Every question asked in the interview is hidden somewhere in your application. Think about it: they've read 400 - 500 of these things. They don't remember yours or anybody else's all that well.

Naturally then, they'll ask you things you've already covered. They'll challenge you to think critically about your idea, how to market it, who is going to use it, and they might even ask how it will make money. All of these things are on the application! Read over it again. Expand on your answers and re-think them.

Bring a demo

Whether or not you have a demo already done, you need one for your interview. Start building it now! We didn't have a demo when we applied, but we had one for our interview thanks to two weeks of non-stop coding (whenever we weren't at our day jobs). Plus, it's nice to be able to say: "Look what we did in two weeks!" If you already had a demo, code like crazy anyways. Show progress.

It doesn't have to be done, it just has to be as much as possible. It gives you something to talk about, and it's nice to show that your ideas are already turning in to reality.

Start your company anyways

If you don't get accepted to YC, you should start your company anyways. You need to believe and show them that if they don't invest in you, they will have missed their chance at being in on the next big thing. PG talks about this frequently - nothing drives acquisitions and investments quite like fear.

Have fun

My mom would be disappointed if I didn't include this mantra in every part of my life. But it's actually true. I hate job interviews - they're very artificial and weird. The YC interview is a conversation that honestly is exhilarating.

Enjoy it - and good luck!

 
 

I just finished (graduated?) YCombinator's Winter program and it has been a truly fantastic 3 months. So many things in my life are so different at this point - I know what I want to do, I know how much I can do, and I know people who can help me do it. I wanted to share some advice from my experience, and I'm going to start from the beginning.

Apply!

My co-founder Wayne and I decided to apply for YC way before the deadline. We spent weeks on our application, and I think this was a Good Thing. The application basically tests three things:

1. Are you a good hacker?

This is the key to getting funded by YC. And, there's really only one way to prove that you are: build something at a public URL. For me, it was Majigs and QuickRef and for Wayne it was Count to Nine. For you, it could be a demo of your product. But make sure they have something to go look at.

2. Can you think through an idea?

This is why I'm glad we spent so much time on our application. The questions on the YC app are crucial - you will have to refine your answers to these as you go further in the program. Things like "What do other people have to do now because your product doesn't exist yet?" are great places to figure out why your product is different, and more importantly, better. Even if you don't get in, your product will be better off for having thought through these questions. They are worth your time and honest appraisal.

3. Are you sane?

I used to direct an improv comedy troupe in college. Every semester we held auditions and it was always an eye-opening experience. You'll never find a more interesting group of people than when you say: "Prove to me that you're interesting". I imagine YC goes through this - except we only had to deal with 60 people auditioning whereas they get hundreds of applications.

I'm not sure how to give advice on how to be sane. I guess, if this question angers you, you probably are not sane.

Better late than never?

The SFP application deadline has passed, and thus this advice comes a bit late. Hopefully it helps the next round of applicants - or helps those of you who get interviews. In any case, good luck!
