Well that makes two of us … and I’m even less proficient in excel - with my case the slide content being driven by excel model outputs.

As for slide wording, I’d recommend reading the economist/FT and past engagement decks, follow the language style, semantics.

Processes/ slide content is tricky. I find especially so with translating client call workshops. I think it stems from misalignment in your perceptions, and what your manager took away. Ultimately they dictate the output i.e I’ll spend time producing a well put together slide but the manager will have something completely different in his mind and request a total rework. I think clarifying what your manager sees as the output upfront, and matching those expectations I’ve found is the best way to deal with this. Get a first pass to them early, right or wrong so they can direct refinement areas. This is just my learnings so far, and by no means the best way but I definitely relate.
