AI Job Interview: How to Train with ChatGPT & Co.

The job interview invitation has arrived – congratulations! But before you can look forward to meeting with HR and the department, you will increasingly face a different kind of interviewer in Switzerland: an artificial intelligence. Video interviews evaluated by AI systems are no longer a rarity in 2026. But even if a human is sitting on the other end, preparing with AI has become your biggest advantage.

Anyone still practicing in front of the mirror today is wasting valuable potential. In this article, we look at how to turn the tables and use AI to prepare for your next job interview.

The Problem: Going into the (AI) Interview Unprepared

Whether you are applying at an SME in Aargau or a major corporation in Zurich: interview processes have changed.

Many candidates fail due to two new hurdles:

1. Unknown questions: The standard question about "three weaknesses" is yesterday's news. Today, competency-based questions are asked that are hard to predict.
2. AI screenings: More and more companies rely on asynchronous video interviews in the first step. Here, an AI analyzes your answers, your facial expressions, and even your choice of words. Anyone stuttering nervously into the camera here gets cut – even before a human has seen the video.

The good news? You can now use the exact same technology for your training.

The Solution: Make AI Your Sparring Partner

You don't have to be a tech nerd to use AI for your preparation. With tools like ChatGPT or Gemini, you can prepare specifically for difficult questions. Here are three concrete tips on how to do it:

1. Simulate the Interview with Voice Mode

Use the voice feature of ChatGPT (or similar tools) on your smartphone. Give the AI the following prompt: "You are the HR manager at [Company] and are conducting a job interview with me for the position of [Position]. Ask me 5 competency-based questions one after another. Wait for my answer after each question. At the end, give me critical feedback on my answers, my persuasiveness, and suggest improvements." This way, you not only practice the content, but also speaking fluently.

2. Decipher the Job Advertisement

Copy the complete job advertisement into the chatbot and ask: "What 10 questions would you, as an experienced recruiter, ask a candidate for this position to check whether they really meet the requirements?" The AI analyzes the hidden requirements and provides you with tailored practice questions.

3. Optimize Your Answers Using the STAR Method

If you have delivered good results in the past, you also need to be able to sell them effectively. Swiss recruiters love the STAR method (Situation, Task, Action, Result). Write down one of your success stories and let the AI analyze it: "Is this answer structured according to the STAR method? How can I formulate the Result (R) even more measurably and persuasively?"

How PARAT Helps You Prepare

The best preparation is useless if your application file was already inconsistent in advance. If you are asked during the interview about gaps in your CV or details in your cover letter, you need to be on solid ground.

This is exactly where PARAT supports you. When you create your CV and your cover letter with PARAT, the AI wizard ensures that your profile is completely consistent and tailored to Swiss standards. You know exactly which strengths were highlighted – and can confidently build on them during the interview. A continuous thread from application to interview!

Conclusion: Use Technology to Your Advantage

Job interviews are stressful enough. Use the tools available to you today to reduce this anxiety. An AI sparring partner is patient, critical, and available to you at any time. Practice until you feel confident.

Good luck with your next interview – you've got this!
