The Top 5 Interview Mistakes

Tom O’Neil, founder of CV.co.nz Tom O’Neil 2 min read

Based on my experience interviewing thousands of people (from CEOs through to new graduates) throughout my career, the same common mistakes continually crop up. What are these universal interview pitfalls, and more importantly, how can you avoid them and secure the job offer?

1. Being Unprepared

This is the most fundamental mistake. It signals a lack of genuine interest and professionalism. This includes:

  • Lacking Company Knowledge: Failing to research the company’s mission, recent news, products, or position in the market.
  • Not Knowing the Role: Not being able to clearly articulate how your skills and experience align with the specific job description.

2. Badmouthing a Previous Employer or Colleague

Interviewers are looking for a team player with a positive attitude, therefore speaking negatively about past employers, managers, or coworkers is a huge red flag. It suggests you might be difficult to work with, lack professionalism, or have poor conflict resolution skills.

3. Poor or Inappropriate Communication

  • Don’t ramble or waffle by giving long, unstructured answers that lose the interviewer’s interest or don’t clearly address the question. Keep your answers concise and focused by using the CAR (Context / Action / Result) method for behavioural questions.
  • Don’t under-sell yourself. Connect your past achievements with tangible results. Also use facts, figures, and examples to prove your value.

4. Failing to Ask Thoughtful Questions

When the interviewer asks, “Do you have any questions for me?” saying “No” suggests you haven’t given the role much thought and aren’t truly invested. This is your chance to show your strategic thinking, learn about the team/culture, and reinforce your interest. Always come prepared with 3-5 well-researched questions about the role, the team’s goals, the company’s direction, or the interviewer’s experience. Pro Tipp: Avoid asking questions whose answers are easily found on the company website

5. Weak Non-Verbal Communication and Appearance

Your body language and initial presentation speak volumes before you even say a word. This can include:

  • Dressing Inappropriately: While dress codes vary, always aim to look neat, polished, and professional. When in doubt, it’s better to be slightly overdressed than underdressed.
  • Poor Body Language: This includes avoiding eye contact, slouching, fidgeting, crossing your arms defensively, or checking your phone.
  • Lack of Enthusiasm: This makes you seem disinterested, regardless of your spoken answers. Show genuine energy and enthusiasm for the opportunity.
