Top Interview Mistakes and Tips

Making mistakes in interviews is a common aspect of the job hunt. What really matters is how you respond. You may transform every setback into a stepping stone by reflecting on your mistakes in the past and preparing yourself better with resources.

Here are some interview mistakes and tips to guide you for the same.

Lack of preparation

One of the most common and destructive interview blunders is underestimating the value of preparation. This includes failing to investigate the organisation, not comprehending the job description, and being unable to describe how your experience relates to the role.

How to Bounce Back:

• Research the company’s mission, values, and recent projects.
• Reviewing the job requirements and mapping them to your skills.
• Practicing responses to common interview questions.

The QIBA Professional Year Programs in IT include models on job readiness, workplace communication, and mock interviews. These training programs prepare students for real-world settings and teach them how to perform effective company research.

Poor Communication Skills

Communication is key in interviews. Speaking too little, rambling, or failing to structure responses can create a negative impression. Furthermore, employing informal language or filler words (“um”, “like”, “you know”) may impair perceived professionalism.

How to Bounce Back:

• Practice active listening.
• Use the STAR method (Situation, Task, Action, Result) to structure responses.
• Rehearse with a friend or mentor to get constructive feedback.

QIBA’s Leadership and Management certifications emphasize interpersonal communication, effective speaking, and team cooperation abilities, which are crucial for job success beyond interviews.

Negative comments about previous employers

Badmouthing former employees or colleagues, even if justified, can make you appear unprofessional and difficult to work with. Employers are seeking team players with a good attitude.

How to Bounce Back:

• Consider how you could reframe the experience more effectively.
• Focus on what you learned from past roles, even if the environment was challenging.
• Emphasize how the events influenced your professional growth.

Not asking questions

When candidates do not ask questions at the end of an interview, it may indicate a lack of enthusiasm or preparation. This is also a missed opportunity to assess if the company is the right fit for you.

How to Bounce Back:

• Prepare at least 2-3 questions in advance.
• Concentrate on the corporate culture, growth possibilities, and role expectations.

Examples:

“How is success measured in this role?”

“What does a typical day look like for someone in this position?”

The Graduate Diploma in Management (Learning) provides training in critical thinking and strategic questioning, enabling professionals to ask meaningful questions that reflect engagement and leadership potential.

Overemphasis on Salary and Benefits

While salary is important, bringing it up too soon, appearing overly focused on compensation, can be a red flag for employers. It could imply that you’re more concerned with the salary than the position.

How to Bounce Back:

• Wait until the interviewer brings up salary, or reserve it for the later stages of the process.
• Express enthusiasm about the role and company first.

Arriving Late or Logging in Late for a Virtual Interview

Being late might indicate a lack of professionalism or poor time management. With virtual interviews becoming more popular, technical faults or failure to test equipment beforehand fall into this category.

How to Bounce Back:

• If you are late, truly apologize and provide a brief explanation without making any excuses.
• Send a follow-up email expressing gratitude and reaffirming your interest in the role.
• Make sure you run a tech check (internet, webcam, microphone) before the next interview.

QIBA’s focus on Australian workplace culture in its programs emphasizes punctuality, reliability, and professional conduct—key soft skills valued by local employers.

Dressing Inappropriately

Dressing too casually, especially for a virtual interview, can convey a lack of professionalism. While workplace dress codes differ, it is ideal to be somewhat overdressed.

How to Bounce Back:

• Learn from the experience and choose more appropriate attire next time.
• Research the company culture and dress code beforehand.

Tip: To maintain a professional appearance during virtual interviews, pay attention to grooming, lighting, and background.

Being too modest or too arrogant

Failure to highlight your accomplishments can make it harder for interviewers to determine your suitability. On the other hand, overconfidence or ignoring team efforts might come out as arrogance.

How to Bounce Back:

• Prepare a few major successes and practice presenting them with confidence and humility.
• Give credit where it is due and position your efforts in a team context.

Courses such as the Diploma of Project Management encourage students to highlight their leadership and accomplishments while also acknowledging teamwork and collaboration.

Not tailoring your responses

Using generic responses or failing to align your answers with the specific role shows a lack of attention to detail. Hiring managers appreciate candidates who can demonstrate relevance and alignment with company goals.

How to Bounce Back:

• Review the job ad carefully and highlight keywords.
• Customize your examples to meet the company’s needs.
• Link your previous work experiences to the specific challenges or responsibilities of the job.

Failure to Follow Up

Not sending a thank-you email after an interview can be seen as disinterest or a lack of professional courtesy. It’s a small step that leaves a big impression.

How to Bounce Back:

• If you missed out, send a courteous message expressing gratitude and reaffirming your interest.
• Use the follow-up to address any points you may have missed or want to clarify.

QIBA’s career readiness training encourages students to build a habit of professional follow-ups and email etiquette, reinforcing good workplace habits from the outset.
