[Tip] Read This Before Your Customer Interviews

"A guide to asking the right questions, avoiding false positives, and uncovering true customer needs."

The purpose of a customer interview is not to fish for compliments or hear that "your idea is great."

The true goal is to find "evidence that your idea might be wrong," thereby drastically reducing the cost of failure.

💡 Pro-Tip for Interviews: Always ask for permission to record the session. Run the audio through an AI transcription tool (like Otter.ai or Clova Note), and use AI to help summarize the key insights.

🚫 3 Leading Questions You Must Never Ask

People naturally want to avoid hurting your feelings, so they will lie to you. The "bad questions" listed below are classic leading questions that force the customer to give you the answer you want to hear.

1. "What do you think of my idea? Isn't it pretty good?" (Asking for Opinions)

• ❌ Why it's bad: Social norms dictate that the other person has no choice but to politely say, "Yes, it sounds great." This creates a dangerous False Positive.
• ✅ What to ask instead: "How did you specifically solve this problem the last time you experienced it?" (Always ask about past 'behavior', not future 'opinions'.)

2. "If we build this, would you pay for it?" (Hypothetical Futures)

• ❌ Why it's bad: No one can accurately predict their future behavior. They will say they'll buy it today, but they will vanish when you actually launch.
• ✅ What to ask instead: "Have you ever spent money or time trying to solve this problem before?" (Verify if the problem is painful enough that they have already opened their wallets to fix it.)

3. "Wouldn't it be convenient to have a feature like this?" (Seeking Agreement)

• ❌ Why it's bad: If you ask a universally obvious question, you will get a universally obvious "Yes." The insight you gain from this is exactly zero.
• ✅ What to ask instead: "What is the most frustrating part about the alternative (or competitor) you are currently using?" (The customer's point of frustration is your exact window of opportunity.)

🧠 Uncovering True Intentions with the '5 Whys' Technique

Customers rarely state their true motivations upfront. Keep asking "Why?" until you dig past the superficial complaints and find their hidden desires.

• Customer: "It's just too annoying to go to the gym."
• You: "Why does it feel so annoying?" (1)
• Customer: "Because I'm exhausted after work."
• You: "If you're that tired, why are you trying to work out in the first place?" (2)
• Customer: "I want to lose weight and do a fitness photoshoot."
• You: "Why is doing a fitness photoshoot important to you right now?" (3)
• Customer: "Honestly... I want to show my ex that I've leveled up and look amazing."

🎯 True Need Discovered: The core motivation here isn't 'health' or 'fitness'—it is 'revenge' and the 'desire for validation'. Recognizing this changes your entire marketing hook.
