The best way to interview Product Managers
I've run a lot of PM and product design interviews. Most optimise for hypotheticals: “What would you build?” or “How would you approach X?” They test theory in...

You paid for research. Someone else got the instincts.
You open your email and see the PDF from the agency. It has clean design. Graphs in pastel colours. 47 slides with themes, personas, quotes and journey maps. You flip through it and give the team a quick overview. It feels like progress.
But it isn't.
While the agency had done customer interviews and, perhaps, workshops, something happened that wasn't on the bill one of the core instincts that sits at the heart of product development roles and responsibilities quietly transferred to someone else. They built the understanding. Not you. Yes, you received the report, but the product instincts went to someone else.
Proper customer research isn't the report. It's not even the goal.
It's what forms in your head when you're sitting across from someone genuinely frustrated with your product.
It's the thing they mention at the end of the call, the twitch in their eyes, and the cheeky smile that appears when something finally clicks and they understand.
There's a moment of silence before they respond to a seemingly straightforward question.
The workaround they've been running for 6 months without saying a word because your feature didn't quite work for them..and they never said anything and as a founder, you're the one who needs to know that.
None of that can be found in a PDF. It lives in the person who was in the room with the customers.
When you outsource the talking, you get information instead of deep understanding.
The agency sharpens their product instincts. Instincts are what tell you which problem is worth solving before the data catches up.
You lose these instincts slowly. Every time someone else picks up the phone instead of you.
Of course, agencies have their uses. Running large scale surveys, finding the right people to talk to, making sense of a mountain of data - they're good at that. But none of it matters if you haven't spoken to a customer yourself in the last month. One conversation. Even when you're busy. Especially when you're busy.
The understanding you build is yours.
If you're a founder who hasn't spoken directly to a customer in the last month, that's worth paying attention to. Not as a task to delegate - as a signal about where your head is in the business. If you want to think through what that means for your product direction, I'm happy to have that conversation.
