Organisers often ask for "a guest speaker" when what they actually need is a judge, or ask for a judge when a mentor would serve their students better. The three roles overlap, but they're not interchangeable.
A speaker informs a room
One-way, time-boxed, works for 50 to 500 people. Best when you want to introduce a topic — what RAG is, why fine-tuning matters, how the AI job market actually looks — to an audience that hasn't built anything yet.
A mentor invests in a smaller group over time
Best for a club or a final-year project team that needs ongoing feedback, not a single afternoon of inspiration. This is closest to what I've done at VSICS and through TechVerse Enclave — recurring contact, not a one-off visit.
A judge evaluates under pressure, once
Needs a transparent rubric shared with participants beforehand, not a gut-feel scorecard. If your event is a hackathon or a pitch competition, this is the role, and it's the one I'm most often asked for now given my own hackathon record on both sides of the table.
If you're not sure which you need
Tell me the format and the audience size, and I'll tell you honestly which role fits — sometimes it's a hybrid, a talk followed by judging the same event's pitches.
