James Hawkins: Since we started PostHog, our team has interviewed 725 people. What's one thing I've taken from this? It's normal for candidates not to ask harder questions about our company, so they usually miss out on a chance to (i) de-risk our company's performance and (ii) to increase the chances they'll like working here. Does the company have product-market fit? This is the single most important thing a company can do to survive and grow. "Do you ever question if you have product-market fit?" "When did you reach product-market fit? How did you know?" "What do you need to do to get to product-market fit?" "What's your revenue? What was it a year ago?" "How many daily active users do you have?"

If these answers show that the founder doesn't have a good product, it's ok. Do you know if they will get to a yes? You can't join a sinking ship. Product-market fit is all that matters to early stage entrepreneurs. Those that are honest about this and prioritize it will succeed. Many will believe that they have it when they don't. A low user or revenue number is a sign that it is not there. The product-market fit is clear.
