Job interviews are like first dates, but with less flirting and more sweaty palms. You want to make a great impression, stand out, and land that dream role. But one slip-up—like talking too much or arriving late—can make all your preparation go to waste.
The good news? Most interview mistakes are completely avoidable. Here’s your ultimate guide to what NOT to do during a job interview—and how to get it right.
1. Talking too much
We get it—you’re nervous, and the words just start tumbling out. But rambling during an interview can make you sound unfocused or, worse, unprepared.
What to do instead:
- Aim to talk for around one to two minutes per question, unless the interviewer asks for more detail.
- Keep your answers concise and relevant.
- Use the STAR method (Situation, Task, Action, Result) to structure responses to competency-based questions.
2. Not listening
Sometimes nerves make us so focused on what we plan to say that we miss the actual question. This can lead to irrelevant or vague answers.
What to do instead:
- Take a breath and actively listen before answering.
- Paraphrase the question if needed—this shows you’re paying attention and gives you time to think.
- If you’re unsure, ask for clarification rather than guessing.
3. Falling into the “relaxed trap”
An experienced interviewer might try to make the conversation feel casual. While this helps build rapport, don’t confuse a friendly tone with an invitation to overshare or go off-topic.
What to do instead:
- Smile and show personality, but steer back to the main topic if the discussion drifts too far.
- Keep things professional, even when chatting about hobbies or personal experiences.
4. Trying to take the lead
Confidence is great—arrogance is not. Coming across as if you’re running the interview or dominating the conversation can turn off recruiters.
What to do instead:
- Focus on teamwork. Use “we” when discussing past projects to show collaboration.
- Balance confidence with humility, acknowledging contributions from others.
5. Not asking questions
Interviews aren’t one-way interrogations—they’re also your chance to show interest. Not asking questions can make you seem disinterested.
What to do instead:
- Ask the interviewer about their experience with the company—it builds connection.
- Prepare 2-3 thoughtful questions about the company, role, or team culture.
6. Being late
Arriving late is the fastest way to start off on the wrong foot. It screams poor time management.
What to do instead:
- Plan to arrive 10–15 minutes early.
- If something unavoidable happens (e.g., traffic, emergencies), call ahead to explain and apologise.
7. Lack of preparation
Failing to research the company or role is a huge red flag. Interviewers want candidates who show genuine interest.
What to do instead:
- Review the company’s website, mission, values, and recent news.
- Familiarise yourself with the job description and identify how your skills align with the role.
8. Poor body language
You might say all the right words, but your body language can betray nervousness or disinterest.
What to do instead:
- Sit up straight, keep your shoulders relaxed, and make eye contact.
- Avoid fidgeting, slouching, or crossing your arms.
- Use natural hand gestures to appear confident and open.
9. Dressing inappropriately
Turning up in casual clothes when the role calls for professionalism can make you seem unprepared.
What to do instead:
- Research the company dress code and aim to be slightly more formal than their usual attire.
- For corporate roles, classic business wear is always safe.
10. Showing no enthusiasm
Recruiters look for candidates who are excited about the opportunity. If you sound flat or uninterested, they’ll move on to someone who truly wants the job.
What to do instead:
- Smile naturally and show positive energy when discussing the role.
- Mention what specifically excites you about working for this company.
11. Badmouthing past employers
Even if your last job was a nightmare, an interview isn’t the place to air grievances. Speaking negatively makes you appear unprofessional.
What to do instead:
- Frame past challenges positively: “I learned a lot from that experience…”
- Focus on your achievements and growth rather than workplace drama.
12. Forgetting to follow up
A thank-you note might seem old-fashioned, but it can make a huge difference. It shows professionalism and reinforces your interest.
What to do instead:
- Highlight a memorable point from the interview and restate your enthusiasm.
- Send a thank-you email within 24 hours.

- Research the interviewer (LinkedIn is your friend).
- Plan your journey or test your video call setup in advance.
- Bring copies of your CV and a notepad.
