5 Interview Mistakes That Could Cost You the Job — and How to Avoid Them

Andrew Farrow • August 13, 2025

You’ve applied, impressed with your CV, and landed the interview - now the real test begins.


An interview is about showing you’re the right fit for the team and the company. Unfortunately, many candidates trip themselves up with avoidable mistakes.


Here are the five most common interview mistakes our recruiters see, and more importantly, how you can avoid them to boost your chances of success.

Mistake 1: Not Researching the Company


Turning up without a clear understanding of the company’s business, values, and industry position sends the wrong message: that you’re not serious about the role.


How to avoid it:

  • Spend at least 20 minutes reviewing the company website.
  • Read recent news articles or press releases.
  • Check their LinkedIn page for updates, new hires, or achievements.


💡 Pro tip: In your answers, reference something you learned in your research - it shows initiative and genuine interest.


Mistake 2: Talking Too Much - or Too Little


Some candidates ramble and lose focus, while others give answers so short they sound disinterested.


How to avoid it:

  • Use the STAR method (Situation, Task, Action, Result) to structure your answers.
  • Keep responses clear, relevant, and to the point.
  • Practice answering common questions aloud before the interview.


Mistake 3: Neglecting Non-Verbal Communication


Your body language speaks before you do. Poor eye contact, slouching, or fidgeting can make you seem nervous or unprepared.


How to avoid it:

  • Sit upright, maintain comfortable eye contact, and offer a firm handshake.
  • Avoid crossing your arms - it can seem defensive.
  • Mirror the interviewer’s tone and energy for better rapport.


Mistake 4: Failing to Prepare Questions


When the interviewer asks, “Do you have any questions?”, saying “No” is a missed opportunity.


How to avoid it:
Prepare 2–3 thoughtful questions, such as:

  • “What does success look like in this role after six months?”
  • “How would you describe the team culture?”
  • “What are the next steps in your hiring process?”


Mistake 5: Forgetting to Follow Up


Many candidates assume their job is done once they leave the interview. But following up can leave a strong final impression.


How to avoid it:

  • Send a short thank-you email within 24 hours.
  • Reiterate your interest and highlight one key point from the interview.


Final Thoughts?


Interviews are as much about preparation and attitude as they are about skills. By avoiding these common mistakes and focusing on presenting your best self, you’ll stand out from the competition.
