TJ Walker shows how to use AI as a mock interviewer for interview prep. Instead of memorizing answers, you speak aloud, get follow-up questions, and receive feedback on vague spots and missing details. Repeating this cycle builds the ability to think and explain under pressure, which is what actually wins interviews.

Ultimize. Now that you can predict the questions, the next step is practicing them in the right way. This is where most candidates fall back into old bad habits. They review notes. They read sample answers. They rehearse silently in their head. That feels like preparation, but it doesn't prepare you for the one thing that actually matters: thinking and speaking out loud under pressure. Let's walk through how to fix that using a specific example. Imagine Alex. He's applying for a customer success manager role at a SaaS company that provides software to HR departments. From his earlier work, he already knows the likely questions— things like, "How do you handle a difficult client?" "Tell me about a time you improved customer retention." Now Alex uses AI to simulate the interview. He opens his AI tool and speaks to it. He pushes the audio microphone button and says, "Act as a hiring manager for a customer success manager role at a SaaS company. Ask me one question at a time based on improving customer retention and handling difficult clients." After each answer, Ask a follow-up question that tests depth. Now the AI becomes the interviewer. It asks, "Tell me about a time you improved customer retention." Alex answers out loud, not in his head, out loud. That's critical. You might say, "In my last role, we noticed that customers were dropping off after the first 3 months. I introduced a structured onboarding process with regular check-ins, and we improved retention by about 15% over 6 months. Now the AI responds with a follow-up: What specifically changed in the onboarding process that made the biggest difference? Now Alex has to think, he has to explain, he has to clarify. This is where real preparation happens, because interviews are not about delivering perfect first answers. They're about handling follow-ups smoothly. Now, Alex goes one step further. After completing a few questions, he asks, evaluate my answers. Tell me what I did right, what I did well, what were the best examples I used, and where was I too vague and where could I have been more specific? Now, the AI might say you gave good overall answers 'Good specific examples, but you didn't explain exactly what the onboarding process included. You mentioned improving retention by 15%, but you didn't explain how you measured it.' Now Alex sees the gaps—not in theory, in his actual performance. Then he repeats the process. He answers again, refines again, improves again, gets feedback again. This is the key shift. You're no longer preparing passively, you're practicing actively. You're building the ability to think, explain, and adapt in real time, and that's what shows up in the interview. Because when you've already spoken your answers out loud multiple times, handled follow-ups, and corrected your weak spots and strengthened your good parts, You don't walk into the interview hoping you perform well. You walk in knowing you're about to do it. That's the power of practicing the right way.
