Ask HN: License to use for an interview project?

I'm in an unusual situation. I'm working on a demo application for a company I'm interviewing with. This has never been an issue before, but in this particular case the scope of the application is closing in on something I would normally build as an mvp or v1 for an internal tool.

Its somewhat surprising to me because the company is rather large and well known, so this isn't a case of the interview app being a way to get free work done.

However, I think I will be more comfortable by including a non-commercial use license with the project. What are some simple licenses I could use? Most searches I've done all return variations of open source ones.
