They were late to our start time but agreed to let me have the full 30 minutes.

I applied for the position and heard back in approximately three weeks.

They contacted me a week prior to have me prepare a deck/presentation on hybrid cloud solutions with a specific prompt.

It was a ~10 minute presentation, and the rest of the time they asked questions, leaving room for two questions at the end.

They suggested I would hear back in a week.

I had to follow up a couple of times before a response was given.

Questions were related to a presentation I gave.

I am looking for how you would express these concepts in a way that is accessible for different levels of expertise.

Do not lie. It is okay to say you are unsure and will follow up with them to provide an accurate answer; however, speaking on what you don't know is not taken well.
