I read that one way to have someone prove their ability to communicate difficult concepts in an easy to understand manner is to ask a question like, “how would you explain a website that is http versus a website that is https to your grandmother.”
First, you may have to familiarize yourself with the technical intricacies of the difference because wait … what does http even stand for? I mean I know s is secure or … like … security but … How does the internet work!?
Anywho, I thought of a question I would ask if I was conducting an interview of someone who I didn’t like because I felt he or she was too cocky: “How would you explain how babies are conceived to your grandmother?” Then when the person insists that their grandma knows or that the question has no relevance for being a clerk at a grocery store I would simply state, “If you want the job,” then I would pause for dramatic effect, “then explain to me, as though I am your grandmother, where babies come from. I went to a Catholic high school so … don’t mind me taking copious notes.”
