One of the best ways to grow as a developer is to build something, destroy it, and build it again. We all have the thought "what other ways can I build this?" in our heads as we're building a project. Most times I have seven different ways to do something, and the hardest part is just picking one. So, in my opinion, a great interview question would be "how else could you have built this?". It shows that the developer weighed the choices that we all inevitably have.

Probably? Do you think that's strange? Pretty standard if you ask me.
