Job interviews can be nerve-wracking, but the real danger isn’t just saying the wrong thing—it’s the small behaviors you don’t even realize you’re doing. Hiring managers pay close attention to every detail, and the way you present yourself can make or break your chances of landing the job. Even if you have the perfect resume, these subtle mistakes could signal to employers that you’re not the right fit.
Before walking into your next interview, make sure you’re not guilty of these 13 interview-killing behaviors.
1. Showing Up Late (Or Too Early)
Punctuality is a direct reflection of your professionalism. Arriving late shows a lack of responsibility and respect for the interviewer’s time. On the other hand, showing up too early—more than 10-15 minutes—can also be a red flag, making it seem like you don’t understand professional timing.
Aim to arrive about 5-10 minutes before your scheduled time. If an emergency delays you, always call ahead and inform the interviewer rather than showing up late without an explanation.
2. Having a Weak Handshake (Or None at All)
Your handshake sets the tone for the interview. A limp handshake can make you seem timid or unconfident, while an overly aggressive one can feel dominating. If you skip the handshake altogether, it might come across as socially awkward or uninterested.
A firm but natural handshake with eye contact creates a confident first impression. If handshakes aren’t expected due to health concerns, a friendly nod and strong verbal greeting will do the trick.
3. Avoiding Eye Contact
Lack of eye contact makes you seem nervous, untrustworthy, or disengaged. While you don’t need to stare down your interviewer, looking around the room or avoiding their gaze can create a disconnect.
Make sure to maintain steady, natural eye contact throughout the conversation. It shows confidence, interest, and respect—qualities every employer looks for.
4. Fidgeting or Playing with Objects
Tapping your foot, playing with a pen, or adjusting your hair repeatedly may seem like small habits, but they’re distracting and signal nervousness. Employers might assume that you lack confidence or struggle under pressure.
If you tend to fidget, practice keeping your hands folded on your lap or using slow, intentional gestures while speaking. Staying calm and composed will make you appear more self-assured.
5. Checking Your Phone

Even glancing at your phone during an interview is a major sign of disrespect. Employers want to know that you’re focused and engaged, not distracted by notifications or messages.
Before your interview, silence your phone or turn it off completely. Keeping it out of sight ensures that you’re fully present in the conversation.
6. Giving Vague or Overly Short Answers
Responding to interview questions with “yes,” “no,” or vague statements shows a lack of enthusiasm and preparation. Employers want detailed responses that highlight your experience, problem-solving skills, and ability to communicate effectively.
Instead of short answers, provide specific examples that demonstrate your abilities. Practice using the STAR method (Situation, Task, Action, Result) to structure your responses.
7. Talking Too Much or Interrupting
While short answers are bad, talking too much can be just as damaging. Rambling off-topic or interrupting the interviewer can make you seem unprepared, lacking in focus, or even arrogant.
Stay concise and listen carefully to the questions. If you catch yourself talking too much, pause and let the interviewer guide the conversation.
8. Speaking Negatively About Past Employers
Complaining about a previous boss or company is a huge red flag. Even if you had a bad experience, criticizing former employers makes you look unprofessional and difficult to work with.
Instead, focus on what you learned from past roles. If asked why you left a job, keep your response neutral and professional without blaming anyone.
9. Lacking Enthusiasm
Employers want candidates who are excited about the opportunity. If you appear uninterested, monotone, or uninspired, they’ll assume you don’t really want the job.
Show enthusiasm by smiling, using engaging body language, and asking thoughtful questions about the role and company. Passion can set you apart from other candidates.
10. Dressing Inappropriately
Dressing too casually—or too formally—can make a bad first impression. A wrinkled outfit, scuffed shoes, or excessive accessories can also make you look unprepared.
Research the company culture and dress one step above their typical attire. When in doubt, business casual or professional clothing is a safe choice.
11. Forgetting to Research the Company
Walking into an interview without knowing anything about the company is a clear sign of laziness. If you don’t understand what they do, how can you convincingly explain why you want to work there?
Before your interview, research the company’s mission, values, and recent news. Being informed allows you to tailor your responses and show that you genuinely care about the position.
12. Failing to Ask Questions
At the end of almost every interview, you’ll be asked if you have any questions. Saying “No, I think I’m good” makes it seem like you’re not truly invested in the role.
Prepare a few thoughtful questions in advance, such as:
- “What does success in this role look like?”
- “Can you describe the company culture?”
- “What are the next steps in the hiring process?”
13. Not Sending a Thank-You Note
Many candidates assume the interview is over once they walk out the door, but failing to follow up with a thank-you email can hurt your chances. A simple message expressing gratitude reinforces your interest in the position and leaves a positive impression.
Within 24 hours of your interview, send a brief but thoughtful thank-you email. Mention something specific from your conversation to make it personal and memorable.
Master Your Interview by Avoiding These Mistakes
An interview is more than just answering questions—it’s about the impression you leave behind. Even if you have the perfect qualifications, small behaviors can ruin your chances without you even realizing it. By being aware of these common mistakes and preparing ahead of time, you can walk into your next interview with confidence and professionalism.
