Job interviews are one of the most critical turning points in your career journey. While the right preparation and approach can bring you one step closer to your dream job, some mistakes made unknowingly can cause you to miss this opportunity. In this article, we examine in detail the most common interview mistakes from the perspective of HR experts and recruitment managers, and how you can avoid them.
Interview Statistics
Critical Mistakes Made Before the Interview
A successful interview begins long before you step into the interview room. Mistakes made during the pre-interview preparation phase can reduce your chances before the interview even begins.
Mistake 1: Insufficient Research About the Company
Employers quickly notice candidates who lack basic knowledge about their company. This is perceived as an indication of the candidate's disinterest in the position and the company.
Do
- Learn about the company's mission and vision
- Research recent projects, achievements, and news
- Gather information about company culture and values
- Analyze its position in the industry and its competitors
Don't
- Don't just quickly glance at the company's website
- Don't ask questions like 'What exactly does your company do?' during the interview
- Don't go to the interview without knowing the company's core products or services
- Don't neglect to research the company's current situation
Mistake 2: Not Analyzing Position Requirements
Many candidates apply without detailed examination of the requirements in the job posting and fail to explain during the interview how they can meet the skills required for the position.
How to Analyze a Position
Examine the job posting in detail to identify the skills and experiences required for the position. Then match them with your own experiences and prepare concrete examples of how you can contribute.
- •Note the keywords and technical requirements in the job description
- •Prepare examples from your own experience for each requirement
- •Identify areas where you may be lacking and consider how you will develop in this area
- •Understand the role of the position within the company and its relationship with other departments
Common Mistakes Made During the Interview
Your behaviors and answers during the interview directly affect the employer's decision about you. Here are the most critical mistakes to avoid during the interview.
Mistake 3: Being Late for the Interview or Canceling at the Last Minute
Punctuality is an indicator of professionalism and respect. Being late for an interview creates a negative impression before you even begin and gives the perception that you are weak in time management.
A candidate being late for an interview is a harbinger that they will also be late for meetings and projects when hired. First impression, especially regarding punctuality, is extremely important.
To Arrive at the Interview on Time
- Plan your transportation the day before the interview
- Arrive at the interview location at least 15 minutes early
- Complete your technical preparations 30 minutes in advance for online interviews
- Allow extra time accounting for factors such as traffic and weather conditions
- Have contact information for the interviewer on hand for emergencies
Mistake 4: Negative Body Language and Weak Communication
55% of communication consists of body language, 38% tone of voice, and only 7% the words spoken. Poor eye contact, loose posture, and inappropriate gestures can negatively affect your evaluation, regardless of how strong your technical competencies are.

Do
- Maintain an upright and confident posture
- Establish regular eye contact
- Use your hands to support your speech
- Practice active listening and don't interrupt the interviewer
- Don't forget to smile
Don't
- Don't display a closed posture by crossing your arms
- Don't constantly check your watch or engage with your phone
- Don't continuously move your feet or tap on the table
- Don't speak too fast or too slow
- Don't make excessive hand gestures
Mistake 5: Speaking Negatively About Previous Employers
Regardless of your reason for leaving your previous job, making negative comments about your former employer, manager, or colleagues during an interview is a major mistake. This behavior is perceived as a lack of professionalism and a potential source of complaints.
Caution!
Instead, focus on how you overcame challenges and what you learned from these experiences. Express your reason for leaving in a professional language and with a development-focused perspective.
Mistake 6: Being Unprepared for Questions
There are some standard questions frequently asked in job interviews. Being unprepared for these questions can be interpreted as a lack of confidence and potentially lead to the elimination of an otherwise strong candidate.
Most Frequently Asked Interview Questions
Preparing for the following questions in advance can significantly improve your interview performance:
- •Tell us about yourself?
- •Why do you think you are suitable for this position?
- •What are your strengths and weaknesses?
- •Where do you see yourself in 5 years?
- •How do you work under pressure?
- •What was the biggest professional challenge you faced and how did you overcome it?
Mistake 7: Stating Salary Expectations Too Early
Bringing up the topic of salary at the beginning of the interview process can create the impression that the candidate is focused solely on money, not on the company and position. This topic should generally be raised by the interviewer in the later stages of the recruitment process.
Do
- First demonstrate your interest in and suitability for the position
- Wait until the interviewer brings up the topic
- Prefer the second or third interview for salary discussions
- Be prepared by researching industry standards and your own value
Don't
- Don't bring up the salary topic yourself in the first interview
- Don't focus solely on your financial expectations
- Don't state figures that are too high or too low
- Don't negotiate salary aggressively
Mistakes Made After the Interview
Mistakes made after the interview can also affect your success in the recruitment process. Here are three important mistakes to avoid after the interview.
Mistake 8: Not Sending a Thank You Email
Sending a thank you email after an interview is an indicator of professionalism and your interest in the position. Many candidates skip this step and miss a valuable opportunity.
Mistake 9: Not Following Up on the Process
Not hearing back for a long time after an interview is a common situation. However, not following up at all can be interpreted as a decline in your interest in the position.
Avoid using an aggressive or impatient tone in your follow-up email. Instead, kindly request an update on the process and indicate your continued interest in the position.
Mistake 10: Not Considering Feedback
Despite all your efforts, you may sometimes receive a rejection. In this case, the most valuable thing you can do is to ask for feedback and learn from this experience.
A failed interview is a valuable learning opportunity that will help you succeed in future interviews. Every rejection brings you one step closer to your dream job.
When you receive feedback, listen instead of becoming defensive and consider how you can apply this feedback in future interviews.
Conclusion: Strategic Approach for Interview Success
Being successful in job interviews is not just about showcasing your technical skills. The steps you take before, during, and after the interview demonstrate your professionalism and interest in the company. By avoiding the 10 critical mistakes mentioned in this article and implementing the suggested strategies, you can significantly increase your interview success rate.
