What Are Interview Mistakes?

One of the crucial steps in job hunting is preparing well for the interview. Many candidates don’t realize they make simple mistakes like neglecting company research, not reviewing the job description, and making communication errors like not listening attentively, or using too much jargon or buzz words. 

In virtual interviews, there are extra challenges. Problems like bad internet connectivity, sudden interruptions, or not maintaining eye contact with the camera can affect your performance. Being aware of the common mistakes can help you prepare better and make a lasting positive impression.   

Why Avoiding Interview Mistakes Is Important? 

Job interviews can make you feel nervous because a small mistake causes you to lose the chance to get the job. Did you know it only takes about 7 to 15 seconds for the interviewer to form the first opinion?

This often happens before you even finish answering the first question!

By then, the interviewer might have already decided if you are the right candidate or not. They pay close attention to things like body language, how you speak, your level of enthusiasm, and the confidence you exude. 

Moreover, interviews usually don’t happen all in one day. Most of the company takes about one week to 30 days depending on the company and role. That’s why performing your best at every stage is essential to win the job offer you want.

Preparation Errors

While preparing for the interview, there are a few key points to note before facing the interview panel. Let’s explore them:

1. Insufficient Research About the Company 

Studies show 47% of recruiters would reject a candidate who had little knowledge about their company. The question “What do you know about the company?” is almost unskippable in any interview. Knowing about the company not just helps you perform better but also lets you decide if it’s a good fit for your own career goals. 

Fix It: Well, prior to the interview, learn about the company,  culture, products, services, and achievements. 

Pro Tip: Check recent news articles, press releases to stay updated about the company’s latest projects. It is good to learn who the company leaders are, read their bios, review their posts, and understand their thinking and values. 

2. Not Practicing Common Interview Questions

We can’t read the mind of the interviewer, but practicing answers to common questions can help you prepare for the job interview. This preparation helps you to structure your answers with clarity.  Not answering a question properly can make the interviewer think you lack preparation. 

Fix It:
Prepare for questions like: 

Tell me about yourself

What are your strengths and weaknesses?

Where do you see yourself in the next five years?

Describe a time when you were faced with a stressful situation at work 

What achievement are you most proud of? 

Pro Tip: Use the STAR method to prepare your answers. (Situation, Task, Action, Result). 

Communication Mistakes

Communication is key in the interview process, regardless of the role you apply for. Both your verbal and written communication matter. Effective communication is not about language, pronunciation, or accent; it’s about how clearly you can convey your ideas. Communication also involves non-verbal cues like body language, eye contact, and tone, which influence how your message is received. Here are some communication mistakes you must avoid: 

3.  Failure to Listen Actively

Often, we try so hard to give great answers that we forget to listen carefully to the questions. This distraction can lead us to miss key details or misread what the recruiter wants to know. Listening can help you stand out from the crowd and do better in the interview. 

Fix It: Pay close attention to the interviewer. Use gestures like a smile or a nod to show you are engaged. Try to keep all your ears out and listen well to the question, process it, and respond thoughtfully. 

Pro Tip: Pause to fully process the question before answering for a clear response. 

4. Inadequate Body Language

Mistake: Many people think that interview success depends completely on what they say, but words account only about 7%. The remaining 93% is based on the nonverbal cues, with 55% influenced by body language. You may choose words carefully, but your body language matters even more. 

Fix It: Start with a firm handshake, sit upright, avoid crossing arms, and maintain steady eye contact. 

Pro Tip: Mirror the recruiter’s posture and tone to show attentiveness and build a strong rapport words.

5. Overusing Jargon or Buzzwords

Saying things like ‘ problem solver’, ‘detail-oriented’, or’ result-driven’ might sound professional, but using excessive buzzwords tends to blur your real value. 

Fix It: Instead, show what you’ve done instead of telling. Give real examples of how you handled challenges. 

Pro Tip: Try this template: “When there was an issue with XXX that caused YYYY, I took the initiative to ZZZ, which resulted in a ( positive outcome). 

6. Never Following Up After the Interview

Many assume the hiring process ends once the final conversation with the employer is over. But a simple follow-up can leave a lasting impression and maximize your chances of success. 

Fix It: Don’t let silence linger. Keep the momentum going with a polite follow-up. 

Pro Tip: Send a Thank You email within 24 hours of the time to express appreciation for the opportunity. If you haven’t heard back after a week, send a short note to show your interest. 

Appearance & First Impression Mistakes

In a few seconds, an interviewer assesses your attitude and behavior irrespective of your professional experience. To make a great first impression, avoid common mistakes and start on the right note.

7. Dressing Inappropriately

Dressing in a way that doesn’t match the company culture or the formality of the role. For example, wearing casual clothes to a formal interview or overly flashy attire can create a negative first impression.

Fix It: Research a company dress code and wear clean, well-fitting clothes to show professionalism. 

Pro Tip: Ask the interview coordinator to understand the company’s dress culture. 

8. Late Arrival and Lack of Punctuality

Punctuality is highly valued in the workplace; arriving a minute late can create a poor first impression and show you are unprofessional. Being late shows you lack respect for others’ time and doubt your reliability. 

Fix It: Plan to arrive at least 15 minutes early to your interview. It will help you manage unexpected delays and allow you to relax before the interview begins. 

Pro Tip: If you are running late, contact your interviewer right away. Apologize and tell them when you’ll arrive.

Interview Mistakes While Answering Questions

Interview mistakes while answering questions include giving vague or rambling responses, not listening carefully, failing to give specific examples, and not engaging with the interviewer through questions. These mistakes show you are unprepared and uninterested,  which decreases your chance of success. 

To avoid this well, focus on clear, concise answers, back them with relevant examples, and actively participate in the conversation. 

9. Rambling or Giving Unclear Answers

Rambling dilutes the message. When you give too much information, you might miss the main points. And employers consider it as a reg flag.

Fix It: 

‣ Draft clear talking points you want to share during the interview. 

‣ Give a structure using the STAR method 

‣ Practice response to common questions

‣ To be on top of your game, you must keep your answers concise and focused

Pro Tip: Try recording your answers and see how long you take.

10. Speaking Negatively About Past Employers

When asked in an  interview “ Why did you choose to leave your past organization?” or “Why did you leave your last employer?” A common mistake is to speak negatively about previous employers. In fact, studies show 48% of candidates badmouth their past employers in an interview. This is a red flag for hiring managers. 

Fix It: Focus on positive reasons like seeking new challenges, career advancement, or personal reasons. 

Pro Tip: Use the sample answer  “I left my previous job because I was looking for new opportunities to grow and develop my skills. I’m grateful for what I learned there, but I’m excited about the potential the role offers for advancing in my career.”

Questions You Should Ask the Interviewer

As a closing note, recruiters inquire, “ Do you have any questions?” This is your best chance to clarify any doubts about job responsibilities, the company culture, and growth opportunities. It shows you’ve done your homework and left a lasting impression. 

11. Why It’s Important to Ask Questions

Many candidates say “no” when they are given a chance to ask a question. This signals to the recruiter a negative and a lack of preparedness. 

Fix It: Prepare a list of questions in advance about the role, team dynamics, organization, their products, and recent or ongoing projects. 

Pro Tip:  Sample questions: 

‣ How would success be defined in this role? 

‣ What are the biggest challenges the team is facing right now? 

12. Examples of Insightful Questions

Asking vague or generic questions is the wrong way to project yourself

Fix It:  Ask questions that show you’ve researched the company and position. And you would be likely to contribute and grow. 

Pro Tip: Consider these insightful questions include:

‣  What are the teams’ biggest goals for this year? 

‣  How does this role contribute to the company’s overall mission?

‣  How is performance measured and reviewed?

‣  What are the next steps in the hiring process?

‣  What qualities do successful employees here share? 

Remote Interview-Specific Mistakes

Virtual interviews are common, and this has allowed companies to find the right candidate. But there are a lot of challenges, often from technical issues and human mistakes. Let’s explore some common mistakes when attending a virtual interview. 

13. Failing to Maintain Eye Contact on Camera

Not looking into the camera will show you are distracted and weaken your connection with the interviewer. 

Fix It: Make a conscious effort to look directly into the camera when speaking, which stimulates eye contact and builds rapport. 

Pro Tip: Try to record yourself or practice in front of the mirror to master the eye contact technique. 

14. Distractions or Poor Internet Connection

Technical glitches, like poor internet connectivity, audio/video issues, or unexpected interruptions, can disrupt the flow. Other distractions like background noise, household members, or notifications can divert your attention and reduce professionalism. 

Fix It: Test your device prior to the interview, like the internet connection, camera, and microphone. Choose quiet, distraction-free space. Close unnecessary apps and browser tabs. 

Pro Tip: Have a backup plan, such as switching to a phone call if the video fails. Stay calm and say what you will do to fix the problem. 

15. Review and Reflect After Each Interview

After every interview, take time to think about what went well and what could be improved. Review your answers. Note the questions that you found hard. A tiny window of reflection helps you to prepare better for the next interview. 

Mistake: After completing the interview, have you ever tried to evaluate yourself? It is easy to just move on to the next, but skipping reflection is missing important lessons for the next time. 

Fix It: Jot down what went well and what was tricky. Be honest with yourself and do not judge. 

Pro Tip: Ask yourself a question about what you did well and what one thing you can improve. Make it a habit after every interview to make you approach the next one with a lot of clarity.
