Job interviews can be stressful, but they’re also your best chance to stand out from other candidates—if you’re prepared. However, many job seekers, especially Gen Z, are unknowingly making avoidable job interview mistakes that leave a bad impression on hiring managers. From being too casual to relying on AI tools during live interviews, these habits can ruin your chances even if your resume looks great. If you want to land your dream role, here are seven common interview mistakes to avoid at all costs.

1. Overusing AI and Sounding Scripted in Job Interviews

AI tools like ChatGPT can help you prepare for interviews, but using them during a live session or copying generic answers can be a dealbreaker. Recruiters report catching candidates with chatbot voices in the background or overly rehearsed answers lacking personal examples. This over-reliance signals a lack of authenticity, and worse, a possible violation of company confidentiality. Remember, employers want to see how you think—not how well an AI can answer for you.

2. Being Unprepared and Too Casual with the Company

Not knowing basic facts about the company is one of the biggest job interview mistakes. Hiring managers consistently point out that many Gen Z candidates fail to research the company or ask thoughtful questions. While it’s okay not to know every detail, showing genuine interest and preparation can make you memorable. Likewise, using informal language or showing up too relaxed—literally still in bed for a video interview—is seen as a lack of professionalism.

3. Lacking Depth, Confidence, or Professional Boundaries

Another recurring issue? Giving shallow answers about your experience or being too honest about personal struggles. While mental health is important, oversharing about your inability to show up for work due to mood can raise red flags. Similarly, asking for flexible hours or four-day weeks before receiving an offer may make you seem entitled. Employers want confidence, not confusion—so focus on presenting clear, relevant examples of your skills without veering into oversharing territory.

4. Forgetting to Follow Up After the Interview

A small, but powerful gesture that many forget: the thank-you note. Recruiters say thoughtful follow-up messages show you’re genuinely interested in the role and respectful of the interviewer’s time. Failing to send one, especially after a great interview, is a missed opportunity. It’s also a chance to reinforce your strengths and clarify anything you may have missed. In a competitive job market, details like this can tip the scales in your favor.

Final Thoughts: Mastering the Job Interview

Avoiding these job interview mistakes could mean the difference between landing the role and getting passed over. Whether you’re a new graduate or an experienced professional, showing preparation, professionalism, and self-awareness will always make you stand out. It’s not about being perfect—it’s about being intentional, authentic, and coachable. Every job interview is a chance to learn, grow, and get closer to your next opportunity.
