How to Spot AI-Generated Answers in Job Interviews (And What to Do About It)

What do you do when a candidate is clearly using AI in a Zoom interview offscreen to answer questions?

I had this happen today (I’m helping someone hire for a role) and one of my questions… just the way the candidate answered set off alarm bells because the answer was AI-shaped – had the right words, but didn’t have the context and depth that comes with actual experience.

A real-time conversation like that is effectively a series of mediocre prompts, and real-time AI APIs use the fastest models possible (like Gemini 2 Flash, GPT-4o, etc.) that have less thinking and reasoning so that their answers are near real-time.

Which means you get word-shaped answers that are plausible if you don’t know the field. If you have subject matter expertise… it smells like AI from a mile away.

I asked a followup question that a human could answer easily and instantly and instead got back an AI answer:

What’s your favorite kind of sandwich?

You know how you’d answer that question. Maybe something like “Well, I don’t really like sandwiches” or “Bacon club” or “Is a taco a sandwich?”.

What you probably would not say was:

“That purely depends on, you know, my mood as well as the situation. So actually it’s about the balance between fresh and also the lean turkey for the efficiency and the creamy avocado for smooth integration.”

Yes, the person was real, but their knowledge was not.

For employers and hiring managers… be sure you have questions that evoke real, human responses (and are non-discriminatory! things like favorite sandwich, favorite album, pineapple on pizza, etc.) that humans can answer easily. And watch how a candidate reacts to these questions versus more knowledge-based questions.

For candidates… I get the allure of using AI to ace a job interview, especially in a difficult job market. That might get you the job – but it probably won’t help you keep the job nearly as well.
