View Interview Books →In this guide, we'll look at nine common job interview mistakes and practical ways to avoid them. The suggestions apply to both in-person and virtual interviews and can be adapted to different roles, industries, and levels of experience.
1. Going Into the Interview Without Enough Preparation
The Common Mistake: Attending an interview without understanding the company, role, or key requirements in the job description.
Why It Can Be a Problem: Without preparation, it can be harder to give relevant examples or explain how your experience connects with the position.
A Better Approach:
- Review the company's website and information about its products or services.
- Read the job description carefully and identify the main skills and responsibilities.
- Prepare examples that demonstrate relevant experience and achievements.
- Review recent company or industry developments when relevant.
2. Overlooking Body Language and Non-Verbal Communication
The Common Mistake: Fidgeting, looking away frequently, slouching, or appearing distracted during the conversation.
Why It Can Be a Problem: Interview communication includes both what you say and how you engage with the interviewer. Distracting habits can make it harder to communicate your points clearly.
A Better Approach:
- Practice mock interviews to become more comfortable speaking about your experience.
- Maintain natural eye contact during an in-person interview.
- Use an attentive posture and avoid unnecessary movements.
- For virtual interviews, look toward the camera when appropriate.
3. Talking Too Much or Giving Very Short Answers
The Common Mistake: Giving long, unfocused answers or responding with too little detail.
Why It Can Be a Problem: Interviewers need enough information to understand your experience, but overly long answers can make important points difficult to identify.
A Better Approach:
- Practice common interview questions before the interview.
- Use the STAR method — Situation, Task, Action, Result — for relevant behavioral questions.
- Lead with the main point and provide supporting details when useful.
- Pause briefly to organise your thoughts instead of rushing into an answer.
4. Not Preparing Questions for the Interviewer
The Common Mistake: Reaching the end of an interview without having any questions prepared.
Why It Can Be a Problem: The question-and-answer portion is also an opportunity to understand the role, team, expectations, and working environment.
A Better Approach:
- Prepare two or three questions before the interview.
- Ask about the responsibilities and priorities of the role.
- Ask how success is measured in the position.
- Ask about the team's working style or the next stages of the hiring process.
5. Arriving Late or Joining a Virtual Interview Unprepared
The Common Mistake: Arriving at the interview location late or joining a virtual interview without checking the technology beforehand.
Why It Can Be a Problem: Unexpected travel delays or technical problems can create unnecessary stress at the start of an interview.
A Better Approach:
- Plan your route and allow extra time for unexpected delays.
- For virtual interviews, test your camera, microphone, internet connection, and meeting link beforehand.
- Keep the interviewer's contact details available in case you experience a technical problem.
- Log in a few minutes before the scheduled time rather than waiting until the last moment.
6. Choosing Inappropriate Interview Attire
The Common Mistake: Wearing clothing that does not suit the company's workplace or the type of role.
A Better Approach:
- Consider the company's workplace culture and the role you are applying for.
- Choose clean, neat, and comfortable clothing that allows you to focus on the conversation.
- If you're uncertain about the expected dress code, business-casual clothing is often a practical starting point, depending on the industry and organisation.
7. Focusing Only on What You Want From the Job
The Common Mistake: Discussing salary, benefits, flexibility, or personal career goals without also explaining how your skills and experience relate to the role.
A Better Approach:
- Explain how your experience relates to the responsibilities in the job description.
- Use specific examples of projects, results, or problems you have worked on.
- Connect your skills with the needs of the role.
- Ask questions that help you understand whether the position is a good fit for your career goals.
8. Speaking Negatively About Previous Employers
The Common Mistake: Focusing heavily on conflicts or negative experiences with previous managers, colleagues, or employers.
Why It Can Be a Problem: Negative comments can distract from the skills and experience you want to demonstrate during the interview.
A Better Approach:
- Keep your explanation factual and professional.
- Focus on what you learned from challenging situations.
- When discussing a difficult experience, explain how you handled it and what you would do differently if appropriate.
- Bring the conversation back to the skills or experience relevant to the new role.
9. Forgetting to Follow Up
The Common Mistake: Ending the interview without sending a professional follow-up when appropriate.
A Better Approach:
- Send a short thank-you message if appropriate for the interview process.
- Thank the interviewer for their time.
- Mention a relevant point from the conversation if there is one.
- Keep the message brief and professional.
