Sharing my writing example exercise from Amazon's interview process

Here is what I submitted to Amazon, as part of their interview process for an L7 Senior Engineering Manager role, in 2020. Depending on the role you're interviewing for, you will get a writing exercise - the one I chose was on Innovation - here's the ask:

Innovation

What is the most inventive or innovative thing you've done? It doesn't have to be something that's patented. It could be a process change, product idea, a new metric or customer facing interface – something that was your idea. It cannot be anything your current or previous employer would deem confidential information. Please provide us with context to understand the invention/innovation. What problem were you seeking to solve? Why was it important? What was the result? Why or how did it make a difference and change things?

Writing Guidelines

1. Write in the style you would use to write a business whitepaper or essay and do not use bullet points, graphics, tables, charts or flow charts.
2. Do not include any confidential or proprietary information from current/past employers.
3. Remember as you write that the reader may not be familiar with specific technical terminology, corporate cultures, and scenarios.  Use language and descriptions in your response that enable readers to fully understand the situation.
4. Please limit your response to 1-2 pages (no more than 8000 characters).

So since I was experimenting going back to being close to technical engineering, I decided to go deep into my past as an engineer, when I invented the Talking EPG:

More than ten years later, a talking interface finally made it to general availability:
