I've watched a lot of professionals pour their energy into learning the latest artificial intelligence tools. For most positions, you don't need to master it, just understand it.

But after four decades of watching people build careers, I keep coming back to one skill that gets you noticed the fastest, and it's not the skill everybody's rushing to master right now. It's public speaking.

Yes, AI can draft your slides. It can even coach your delivery. But when you're standing in front of a room or on a Zoom call with a client, nobody's evaluating your software. They're evaluating you — your ideas, your presence, your poise — and whether they trust what you're telling them.

Every project update, every client pitch, every meeting you lead is public speaking, whether you'd call it that or not.

Our company has hired thousands of people over the years for our clients. The ones who move up the ladder aren't always the most technically skilled. Instead, they're the ones who can stand up and explain why their work matters.

People who can stand up and communicate — persuade a room, calm a nervous client, rally a team — are becoming more valuable, not less. And the rise of AI has made those human skills even more valuable.

Maybe the hardest public speaking event during a job search — and the ultimate test of impromptu speaking — is the dreaded 30-second elevator speech. It's all about you, and it should be a smooth, persuasive 30-second pitch describing yourself and explaining your career goals. As a networking tool, it will open doors for you.

Whether you're in a job search or considering a job change, public speaking is your leading edge.

Whenever I’ve taught Navy SEALs about how to transition into the private sector, it’s the most feared part of the class. It’s also fun to watch how competitive the students become. We pretend that they’re coming into the elevator when it opens on their floor. They have 30 seconds to introduce themselves and get into their pitch before we reach my floor. At first, they keep begging for do-overs and each time, they get noticeably better.

Why does this matter so much?

I can't tell you how many times I've run into an acquaintance I knew was in a job search. I'll ask, "How are you doing?" and they'll say, "Fine." Then we part ways, or drift into small talk about something else entirely.

What should happen is they tell me they're in the middle of a job search. Then, I take the bait and ask, "What kind of job are you looking for?" What often follows is a few minutes of rambling, unfocused chatter about how they're not sure what they want to do. It's hard to network with someone on your behalf when they don't even know what they want.

A far more effective 30-second pitch should include: degree, years of experience, target companies, and a clear ask. That's enough for me to actually help. Keep learning the AI tools if they're useful to you. But don't let stage fright talk you out of the very thing that sets you apart.

The organizations changing the fastest right now need people who can lead them — out loud, in the room, with poise and confidence. The elevator speech is the first test of whether a candidate can communicate their own story effectively. Pass that test, and the rest gets a whole lot easier.
