10 Job Interview Mistakes You Might Be Making

So, you have landed an interview - congratulations! Let the preparation begin.

It’s only natural to feel nervous about an interview, but preparation is key to keeping calm and impressing the hiring team. 

While the right preparation is crucial, there are some common mistakes which can significantly impact your interview. 

Some examples of common mistakes include:​

  • Showing up unprepared
  • Lack of enthusiasm
  • Weak body language
  • Rambling answers
  • No questions for the interviewer
  • Disregarding soft skills
  • Failing to follow up 
  • Badmouthing previous employers

Let's explore these interview mistakes and, more importantly, discuss how to avoid them and what to do instead.

❌ Mistake #1: Showing Up Unprepared

The more you know, the more confident and impressive you'll appear to the interviewer.

Arriving late is a critical mistake that can potentially set the tone for the rest of your interview. Punctuality is a reflection of your professionalismand respect for the interviewer’s time.

✅ What to Do Instead: Plan Ahead. Plan your journey in advance and consider possible delays. Aim to arrive at least 10-15 minutes early for the interview. This gives you time to find the exact location, compose yourself, review your notes, and demonstrate that you value the opportunity and the interviewer's time.

❌ Mistake #3: Lack of Enthusiasm

Lack of enthusiasm can be a major red flag for hiring managers. Vague answers and an uninspired attitude can convey disinterestin the role and the company.  

✅ What to Do Instead: Express Keen Interest

Employers seek candidates who are genuinely excited about joining their team. Smile, maintain eye contact, and show enthusiasm throughout the interview. Let your passion for the role and the company shine through in your answers. Enthusiasm is infectious and can leave a lasting positive impression.

❌ Mistake #4: Weak Body Language

Weak body language such as poor posture, lack of eye contact or fidgeting can also imply disinterest and a negative attitude, undermining your chances of leaving a good impression. 

✅ What to Do Instead: Project Confidence

Your body language speaks volumes about your personality and professionalismAvoid slouching or fidgetingas it can convey nervousness or disinterest. Instead, give a firm handshake, maintain a good posture and aim to project confidence. Active listening and nodding while the interviewer speaks show engagement and respect.

❌ Mistake #6: Dressing Inappropriately
Underdressing or overdressing for an interview can send the wrong message to the employer and may indicate a lack of understanding of the company's culture and expectations. Appearance plays a significant role in making a positive first impression.

Research the company’s dress code before the interview. When in doubt, it’s best to err on the side of dressing slightly more formally than the company’s typical attire. Choose professional clothing that aligns with the role and company culture. Pay attention to grooming and personal presentation to ensure a polished and confident appearance. 

✅ What to Do Instead: Dress For the role you want

Choose professional and well-fitting clothing that aligns with the company's culture. Pay attention to grooming and personal presentation to ensure you convey a polished and confident image.

Long-winded responses can lead to lost focusand affect your chances. Going off on tangents or providing excessive details may dilute the impact of your answers.

✅ What to Do Instead: Be Clear and Concise.

Practice answering relevant interview questions concisely, highlighting your achievements and relevant experiences. Aim to keep your responses structured, to the point, and aligned with the question asked. Don’t be afraid to take a few seconds to think before you answer! 

❌ Mistake #8: No Questions for the Interviewer

Not having any questions prepared can signal to the interviewer that you haven't researched the company or thought critically about the role. It may convey a lack of preparation and enthusiasm for the opportunity and put you at a disadvantage compared to candidates who have prepared relevant inquiries.


✅ What to Do Instead: Prepare Thoughtful Questions
Interviews are a two-way street. Prepare thoughtful questions that demonstrate your interest in the companyand the role. Inquire about the team dynamics, future projects, or growth opportunities. Engaging questions show that you're serious about the position and are considering how well you would fit within the organisation.

❌ #9: Negotiating During the Interview

Bringing up negotiations too early in the interview process might come across as presumptuous and could divert the focus from discussing your qualifications and fit for the role.

✅ What to Do Instead: Focus On Landing The Role

During the interview, focus on showcasing your qualifications, enthusiasm for the role, and alignment with the company's values. Save compensation discussions for later stages in the hiring process, ideally after receiving a job offer.

❌ Mistake #10: Speaking Negatively Of Previous Employers

A major red flag for potential employers is candidates exposing negative experiences or badmouthing previous employers. This can be perceived as unprofessional and raise concerns about your attitude and ability to handle workplace conflicts.

✅ What to Do Instead: Stay Positive and Professional

Focus on sharing constructive experiences and lessons learned from past rolesEmployers want to hire candidates with a positive attitude and the ability to work collaboratively. Highlight instances where you successfully resolved conflicts or improved work processes and demonstrate how specific challenges have shaped your professional growth and problem-solving skills.
