Each day that Cooper was in the office, each intern would have to summarize and give an opinion on an article from that morning's news. He would criticize and give tips on your presentation, and by the end I felt comfortable doing it, while it was difficult at first. This helped me practice thinking on my feet under pressure.
What I wish was different
I did very little actual office "work", but this internship wasn't structured this way, so I understand this.
Advice
Put some time into the paper you have to write beforehand, Cooper will read and edit them.
