Not sure I completely answer the question. Typically when I ask candidates to give a presentation, it's less about the specific products they're presenting, but rather HOW they present it. Can the candidate articulate how they effectively approached their GTM strategy, from ideation to execution and beyond. Can they effectively launch a product/feature and properly engage the right cross-functional partners to make that launch a success? Are they outcome-oriented and think about the metrics they're trying to drive with a given launch? Those are just a few things that I would be looking for in a presentation.
I would also add: Can they clearly understand the customer pain points and technical capabilities of the product, and translate that into clear marketing messages that resonate?
The folks that I've seen who stood out were able to tell a story with their presentation and were clearly outcome-oriented vs tactic-oriented. I don't want someone who's just going to go through the motions. I want a critical thinker who will think outside the box.
