I asked a teacher in high school once how he actually grades exams. I think it was the history teacher, or a teacher of another subject that invites verbose and unstructured answers from students.
Students were trying to cram in as much material as possible in the answers (the shot of hail approach) to maximize the probability that they got something down on paper that could deliver them points. Students also tended to pepper their writing with buzzwords, or complicated language to show off their mastery of the subject.
The teacher on the other hand simply had a list of a handful of short bullet points and you got subpoints for whether it was included in your answer or not. No bonus points for elaborations, or verbal padding.
That teacher is a bit like a potential customer or investor evaluating your pitch.
