You Ask, I Answer: Screening Candidates Faking AI Expertise

In today's episode, Renan asks. Oh, Rennan asks, how do you set up screening to filter out candidates who use Chat GPT to fake expertise? So as a hiring manager, that is a very, very interesting question because it's something I've had to deal with. I've been helping one of our clients recruit. And yeah, there's a lot of people who use generative AI to really, some of them are exaggerating, some of them are as checking boxes on terms, some of them are outright lying and just saying stuff just to get their foot in the door.

And it shows. Boy, does it show. Here's the thing. To the best of your ability, A set up questions that are difficult for an AI to answer coherently and well based on the candidate's experience, because they will not put that, there's not enough detail in your standard resume or CV to be able to come up with a highly specific answer. So let's say somebody works for, I don't know, um, JP Morgan Chase.

If you ask the question like, explain how you uh explain how you handle, I don't know, building a content marketing campaign, chat GPT is going to make a pretty easy, very generic answer out of that, or they're gonna polish up a resume to sound like that. If you ask them at JP Morgan Chase in the fall 2025 campaign, what was your contribution to the campaign? That's not going to be on their CV. That's not going to be something, that's not a level of detail that ChatGPT is going to have information on either, because it's going to be, even if it's not confidential, it's still just not going to be public. And so you have to pivot your interviewing style to be very specific about the candidate's specific experiences.

What did you do? And you can tell if you listen carefully, um, you can tell when someone is has used AI or is using AI in the interview to answer the questions because you will very often get vague answer shaped responses that don't have enough detail. And when you press that person, the model itself, if they're using it in real time, will start to hallucinate and not and make things up. I had this happen with a candidate where the candidate was literally reading off the screen. They had a little teleprompter set up that and chat GPT was giving them the answers.

And I knew it was ChatGPT because I have a couple of trigger questions where I genuinely know how chat GPT answers that question. Um, and I know when once someone's answering it for real versus when someone's answering it for um uh well bit reading off the screen. One of them, I'll give you this one because it's it's it's low risk. I ask a person what their favorite sandwich is, and chat GPT does not know what to do with that question. It's not an inappropriate question, it's not illegal, it's not something that would get you in trouble with HR.

But boy, is it revealing when you spot somebody who's using Chat GPT because they give you an answer that's so weird. They give an answers like so. For the for the best combination of flavor and texture? I prefer a turkey and avocado sandwich. Like, nobody speaks like that.

Most people will be like, uh, I don't like sandwiches, right? Or you know, chicken sandwich or ham sandwich or something along those lines. But you get a human answer that has no hesitation, that has no thinking about it, or has a lot of thinking if they're an overthinker. Um, but you get an answer that is highly specific. That is the if I could if I could sum up everything in the recruiting space with AI.

AI models cannot synthesize highly specific answers to questions because they don't have the information. They simply don't have the data to create a highly specific answer from a given position. And so that is how you work around people using AI for everything and recruiting because you're right. Right now, everybody sounds identical on their resume on their CV. Everybody sounds like they're the best thing since sliced bread, that they're amazing, that they've they've single-handedly save the entire company eight times over, that um and so on and so forth.

It's why things like you know, these the exams people come up with are getting more complex and more convoluted because everybody's like, yeah, we don't know how to deal with this issue of AI. The answer is specificity. Dig deep into a candidate's individual background, what they say they did, where they work. Um, especially for hands on roles, especially for junior roles, uh, you will very, very quickly weed out the the wheat from the chaff because there's a bunch of things that someone would do in a junior role that might not be super impactful, but are gonna be highly specific. So if you were saying talking to somebody who worked at a PR firm, say, like, well, so tell me what your your average day looks like, right?

Um, what do you do day to day? And if they're using AI, they are not going to have a good answer. They're gonna have very generic answers. Oh, well, I do a number of tasks um throughout the day, sometimes including press release templates and things, and then you drill down and immediately you say, Okay, great. How do you make a press release template at your firm?

What's what's the standard at that firm? Suddenly the machine's gonna run into issues because the machine won't have that data. If you ask generically, you know, how do you improve a press release template? Chat GPT can answer that. But if you ask how does Trust Insights write press release templates, right?

How does Trust Insights look at Google Analytics? What is one thing that Trust Insights does in its Google Analytics that you've never seen anywhere else? Or what is one thing that you were taught by your supervisor uh that really stuck with you? Um, who was your supervisor? Right?

Again, specificity is where the rubber meets the road and where AI falls down. So that's gonna do for this episode. Thanks for asking. Talk to you on the next one.
