The fluorescent lights of the conference room hummed, a low-frequency drone that matched the buzzing in Maya’s chest. She had thirty minutes.
The prompt sitting in front of her was deceptively simple: “Design an ATM for children.”
Maya glanced around the table. Three senior product designers from Nebula Tech watched her with polite, unreadable expressions. This was the final round. The gatekeeper between her and the junior role she desperately wanted.
Her mind went blank. An ATM for kids? Should it look like a toy? Should it talk? Should it dispense candy?
Panic began to tighten her throat. She instinctively reached for her bag. Her fingers brushed against the crumpled, coffee-stained edge of a document she had spent the last month memorizing.
It was her lifeline. A downloaded PDF she’d found late one night on a design forum, titled simply: Solving Product Design Exercises: Questions & Answers.
She didn't pull it out—obviously. But she didn't need to. She had spent weeks internalizing its structure. It wasn’t just a list of answers; it was a storybook of logic. She closed her eyes for a second, visualizing the table of contents.
Chapter 1: Define the Problem.
Maya took a breath and opened her eyes. She looked at the lead interviewer, a man with silver-rimmed glasses named David.
"Before I start sketching," Maya began, her voice steadier than she felt, "I want to make sure I understand the problem space. When we say 'ATM for children,' are we solving for financial literacy? Or are we solving for parental control?"
David raised an eyebrow, impressed. "Good question. Let's say it’s for financial literacy."
Maya nodded. In the PDF, she remembered an exercise about designing a mailbox. The answer wasn't the mailbox; the answer was the framework. Who is the user? What is their goal?
"Okay," Maya said, picking up a dry-erase marker. "I'm going to walk through this using a basic structure. First, the User Persona."
She drew a stick figure. "Let’s call him Leo. He’s seven. He gets an allowance, but he loses cash. His goal is to save for a LEGO set. His mom’s goal is to teach him the value of money without him losing the physical bills."
She moved to the whiteboard.
Chapter 3: Brainstorming Solutions.
The PDF had a specific question about a 'Vending Machine for the Blind.' The answer emphasized multisensory interaction. Maya applied that logic here.
"For a kid like Leo, a standard ATM interface is intimidating. Too many buttons, too text-heavy," Maya said. "I propose a screen that uses iconography over text. Bright colors. Gamification."
She sketched a screen. Instead of 'Withdraw Funds,' she drew a picture of a piggy bank with a downward arrow. Instead of a receipt printer, she sketched a sticker dispenser.
"So," Maya continued, "Leo inserts his card—which could be a plastic tag tied to his wrist so he doesn't lose it. The machine greets him by name using audio, which helps with accessibility and engagement. He wants to deposit ten dollars. Instead of just

Generate 3-5 distinct ideas. Avoid judging early. Weaknesses
Take one sheet of paper. Fold it into 8 squares. Give yourself 60 seconds to sketch 8 distinct solutions. They can be ugly. Don't edit. This forces you past the "obvious" answer (the shopping cart) to the interesting one (voice ordering, auto-refill, physical button).
