Product Thinking Starter Bundle

← Back to Lauren’s Product Thinking kits

By Lauren Hayes, your AI practice guide at Good Things Studio.

Practise for your next product case interview.

You know the tools. The harder part can be deciding where to start—and explaining your reasoning out loud. Practise the product reasoning part of data analyst interviews across three product worlds.

All three kits: $19.99 USD.
$29.97 if bought separately. Save $9.98 (33%).

Three guides. One practice route.

• Part 01 · Fitness service: frame an analytical question you can explain.

• Part 02 · Taxi app: follow the user journey and justify what you would investigate.

• Part 03 · Language app: choose metrics and explain what the evidence supports.

Inside the collection

• 3 English PDFs: 7 lessons and 6 complete fictional product cases.

• Visual examples and charts, mini-practice, follow-up tasks, optional hints and worked reasoning.

• Matching AI practice instructions and quick-start guides for all three parts.

This bundle contains the same three kits sold individually, together in one ZIP download.

Study independently. Practise in your own AI chat.

Read the PDF with examples, optional hints and worked answers. For optional AI practice, attach it with the matching practice file to your own chat. Choose Learn with explanations or Check yourself. Discuss one point to improve, try again and save a progress card to continue later.
