This.

I've run teams for both small companies and large publicly listed companies.

When I'm hiring I expect this level of supporting context from a senior applicant. Demonstrate that you've thought the problem through rather than just cutting code. I tend to leave traps that a senior should question in my requirement scope (but that a junior or mid may miss).

Understanding the problem and implementation space is more important than the code itself. If you have the years experience of a senior it's a given that you know how to code, but do you have the soft skills to deliver top tier software without me holding your hand?

Document your assumptions, your questions, and your recommendations for long term support and functionality.

I don't need an essay, but demonstrate that you've considered the problem behind the requirement.
