Building a strong resume may catch a human or AI recruiter’s eye, but that’s only half the battle. Getting a job interview is tough in today’s competitive market. Candidates must display their expertise, skills, knowledge and experience to secure a spot on the interviewer’s desk. Performing exceptionally well during the interview ultimately helps to stand out from the competition and makes the difference between landing an offer and not getting the job.
Interview skills require preparation, self-awareness, effective communication and professionalism. In an interview, hiring managers evaluate more than technical competency and knowledge. They also assess attitude, confidence, curiosity, enthusiasm, and presence under stress. Even highly experienced and qualified professionals can struggle if they walk into interviews without preparation.
Here are some common interview blunders job seekers make during interviews and tips to avoid them:
1. Walking in cold on the company
Knowing about the company’s services or products before the interview shows you’re serious, prepared, interested and motivated. About 21% of employers say it’s a red flag when a job seeker doesn’t know much about the organization or its business. Review the company’s website, social media pages, recent reports or press releases before the interview. Take one step ahead, understand the company’s mission, who their competitors are and industry trends that might affect their business.
2. Thinking of the interview like a simple question-and-answer session
An interview is a professional conversation where interviewers try to understand a candidate’s expertise, skills, and personality. Since it’s a two-way street, candidates aren’t there just to listen and answer questions. It’s up to them to ask insightful questions. Once a candidate has done their research, it’s important to come to an interview prepared with questions:
- Success – What does success look like in this role in 6–12 months?
- Team and culture – How would you describe the team dynamic and workplace culture?
- Growth – What learning or growth opportunities are available?
- Challenges- What are the biggest challenges in this role?
- Company – What are the company’s top priorities this year?
3. Over-prepping with AI
More than 45% of job seekers use AI tools to prepare for interviews, relying on platforms such as Google’s Interview Warmup, OpenAI’s ChatGPT, Final Round AI and other interview simulation tools. Candidates practise responses, rehearse common interview questions, refine communication skills, improve confidence and reduce pre-interview anxiety. But AI-generated responses often produce answers that feel overly safe, scripted and robotic. This causes recruiters to doubt candidates’ communication skills and whether they are fit for the role, leading even highly qualified applicants to be overlooked.
4. Poor communication and vague responses
The hiring manager won’t accurately understand a candidate’s abilities and suitability for the role if they don’t clearly convey their skills, accomplishments, and previous experience. Vague answers, poor communication skills, dishonest replies and confusing narratives show the candidate lacks confidence and transparency.
To communicate effectively, candidates should be familiar with the STAR interview method or the Situation, Task, Action and Result approach. This gives an interviewer an easy way to understand the details of how a candidate has handled previous issues.
For instance, if an interviewer asks when and how the candidate handled any difficult workplace situation, then an engaging answer can include the STAR technique by:
- explaining any tricky situation faced
- mention the task they were responsible for
- give details of the action they took to handle and resolve the situation
- state the result achieved by the steps taken by them
Eye contact also plays a vital role in communicating the candidate’s attitude, interest, and confidence. Maintaining eye contact shows the candidate’s interest and confidence in an interview. But avoid staring; one should maintain eye contact for about 50% of the time while speaking and 70% while listening.

5. Virtual interview flops
As interviews are increasingly conducted digitally, via video or audio, many applicants lack professionalism and do not perform a technical test on their devices. A review states that many interviewers form opinions within the first 30 seconds of an interview. Make sure that the lighting, camera, internet connection, interview platform or app, microphone and audio are all working properly beforehand. Also, select a quiet, clean, and decluttered space with proper lighting to make a professional impression during a virtual interview.
About 53% of interviewers noticed that candidates arrive late and 51% of candidates are not attentive during the interview. Employers also find that 38% of candidates are unprepared for basic questions, indicating a lack of preparation and interest in the job role. Arriving at the interview venue at least 15 minutes before the interview will give you enough time to breathe, relax, and be punctual without rushing.
6. Not following up
Following up after an interview with the hiring manager reinforces professionalism and reaffirms genuine enthusiasm and interest in the job role. Do not miss writing back a short thank-you message to your interviewer within 24 hours to leave a professional and memorable impression. A short follow-up note should thank the interviewer for their time, along with briefly mentioning any of these points:
- any specific discussion
- takeaway from the interview
- reinforce why the role aligns with the candidate’s skills and interests
- express continued enthusiasm for the opportunity
- to clarify an answer
- provide additional information; or
- highlight an important achievement that is missed during the interview
How to improve performance as digital interview processes prevail
There’s a dramatic transformation in the interviewing process due to the widespread use of AI and AI-driven hiring tools, such as AI-powered video interviews, chatbot interviews, and simulated interviews. Although an AI-powered interview process can reduce recruiters’ time on screening candidates by 75%, quality candidates remain interviewers’ priority. Hiring managers still look for desired characteristics in job seekers, such as communication skills, enthusiasm, critical-thinking ability, professionalism, adaptability and authenticity.
Candidates can prepare for interviews using technology, but interpersonal skills, communication skills, emotional quotient, professionalism, and genuineness remain significant in hiring. Those who don’t research the organization, are unable to communicate effectively, and skip asking relevant questions during an interview may lose the dream job despite having qualifications and extensive experience.
Keeping oneself away from these common blunders while remaining genuinely confident and conversational can give candidates an extra edge. Candidates must avoid these six common mistakes to appear confident, leave a strong impression, stand out in the competition, and succeed in the interview. Remember, a well-prepared mindset can help you find a job you love.
