Frankly, this exercise is straight out of Presentation Skills training. My company is big on sending us to a two day course where we have to present on Day 1, get video recorded, played back, critiqued, critique ourselves and then on Day 2, present the same presentation after fixing all the things we were doing wrong on Day 1.
I've incorporated part of this into the new hire training class I run for Sales Engineers. I give them the task of creating a 3 slide presentation on any topic of their choosing and they present, get critiqued, fix it and then re-present the same presentation after fixing it. I give them 8 minutes for 3 slides which is really too much time but that's when I give them the hard stop.
What I'm looking for when we do this is:
- Do they have any passion in their soul about any topic at all and could I channel that passion into what we do for work?
- Do they have any ability to stand up in front of the room and present convincingly?
- How do they react to questions, critique, and even audience members who are uninterested?
I've been doing this for about 2 years now and I've found that I've also had to put a few constraints on the presentations.
Has to be safe for work - one guy wanted to do a presentation on marijuana (really)
Can't be too "heavy" - I had one Jewish guy who knew I was from Saudi Arabia do a presentation on how great Israel is and how terrible Saudi Arabia is. And I had one guy give a presentation on a topic he was utterly passionate about which was adopting abused kids. His stories were heart-wrenching. The stories overshadowed the presentation and left everybody feeling terrible.
Along the lines of what you're being asked to do, a few years back, I had to interview new candidates for my team and I interviewed this German guy. He was insulted when I asked him basic technical questions and his answers to most of my questions left me feeling that the guy could do the job but, I wasn't enthused about him joining my team. Then, after 55 minutes on the phone, I asked him one final question - what do you like to do outside of work? This was the answer that won me over. After 55 minutes of boring interview, he unleashed his passion for Formula 1. This guy talked about the technology of the cars, the racetracks, the drivers, the teams, the manufacturers, etc. He went on for about 15-20 minutes but, it was the passion that he showed for Formula 1 that won me over. It's been 6 years now and he is without a doubt one of the best hires I ever made.
So, in summary, you've got about 3-5 slides to show them that you know something about something. Don't clutter your slides with too much text or two many graphics. Use words and images that will support what you're saying.
In my training class, I encourage people to give some background on slide one, talk about current issues on slide 2 and talk about future issues on slide 3.
Some great topics I've seen presented by my students:
- How to harvest your own tomatoes and create your own pasta sauce from scratch
- Riding some motorcycle trail in North Carolina called the Devil's Tail or something like that
- A presentation on a Swedish run/swim endurance race called Otillo
- A presentation on the sport of Fencing
- The NBA Draft - I didn't care about the topic but, the way the guy presented it, made me interested
In summary, it is not so much the topic but the presentation delivery, the subject matter expertise displayed and the confidence and enthusiasm.
When I have students who try to talk about some industry topic like "Cloud", they always come up short. It's the people who really give a damn about their passion who do really well and make me want to work with them and hear more about what they have to say.
Hope that helps.
