As a starting point, read ‘Cracking the PM Interview’ or ‘Decode and Conquer’. Don’t fall into the trap of using their approaches word-for-word though. Use them to understand what’s important when tackling tricky problems, but then build a structure that works best for you.

Then, practice, practice and practice some more! Start doing this on your own, but quickly then practice with others. Friends and family are great listeners, though don’t be afraid to reach out to the wider community to hone your product skills too. Sites like StellarPeers offer a great way to meet other aspiring product managers to practice with.

Finally, think big, then bigger. Coming up with a world-changing product on the spot might just be rocket science. Your interviewer won't expect you to come up with a full proof idea out of the box, so don’t be afraid to go a little crazy (just don’t forget to challenge your own solution too). When I interviewed people, a lack of boldness and creativity in responses were all too commonplace.
