Do you guys think that putting a simple answer is sufficient, or can I add more to explain my choices?
For example, if my favorite movie is School of Rock, can I add what I like about the movie? Or just simply put the movie title?
It’s intended to be a very short answer. There is no need to explain unless you feel compelled by something that you feel could be perceived as questionable.
Sounds to me like they just want to quickly find out more about your personality. I would just put the title
Have fun with this, kiddo. They’re telling you to just be you - now, lightning fast - show me who you are!
