The success of interviews is also determined by how much we can avoid common mistakes in interviews.

An interview can be an overwhelming and stressful experience. Eventually, every one of us will probably face at least one in our lives. Therefore, it is essential to be aware of some common mistakes and how to avoid them. Several factors can determine the final result and decision of the interviewer, and most of them depend on you and your actions.

Firstly, this article will list some of the common interview mistakes. Secondly, the focus will be on tips on how to avoid them and finally, will be mentioned the interviewer's point of view, with a deeper analysis of what is expected from you as a candidate.

Common interview mistakes

  1. late arrival

  2. being unprepared

  3. inappropriate dress

  4. poor body language

  5. using your phone

  6. lying

  7. talking too much/not talking enough

  8. not asking questions

  9. focusing only on yourself

  10. not reaching the interview

Late arrival

The bare minimum, as arriving a few minutes before the interview can impact the whole process. It will give you time to get ready, calm down and lower the stress. Therefore, do not underestimate this small effort, and be there sooner rather than later. Late arrival can give the interviewer a wrong impression of you being unpunctual, unreliable, and incapable of good time management.

Being unprepared

Relying only on your personality and hoping it will be enough to impress the interviewer, it's not the best idea when getting ready for an interview. Proper preparation can only demonstrate your will and determination to get the position, increasing the chances of actually getting it. Show your interest in the organisation, what is the market position, who are the competitors, what is the organisational background, etc.

Lying can potentionally expose you and lead to an unsuccessfull interview.


Lying and exaggerating about your skills might be very tempting when being interviewed. We obviously want to look better and make a better impression. However, it can be more damaging in the long term since some of those lies might appear during some projects and tasks. The interviewers will appreciate more when you give them an honest and truthful answer, showing your credibility and likability when providing information.

Talking too much/not talking enough

Stress can impact many aspects, which, in a normal situation, might be completely different. It is very natural to higher the voice, ramble or speak very fast when being interviewed. Unfortunately, it can make a wrong impression on the interviewer and thus the decision as a whole. Try to calm yourself down, speak clearly, and at a comfortable pace to avoid being misheard. On the other hand, not talking enough or giving brief answers will not make a good impression either. Try to avoid these common mistakes, and if there is anything you need to clarify, politely ask the interviewer to repeat the question.

What is expected from you

Interviewers have certain expectations from the candidates. Commonly about basic aspects, such as the time of arrival, presentation, dress code or body language. These expectations can be successfully passed only by making an effort. Thus, do not underestimate them and take the first important step for a well-resulting interview. Additionally, bear in mind that being prepared, asking questions, and telling the truth is the most likely way to succeed. Follow these rules, avoid the mistakes listed above, and the interview will be yours.
