10 Things You Should Never Say During a Job Interview

Avoid common interview mistakes that hurt your chances. Learn the top things you should never say during a job interview and what to say instead for a strong first impression.

A job interview is more than a conversation—it's your opportunity to show professionalism, confidence, and cultural fit. While many candidates prepare what they "want" to say, far fewer prepare what they should "never" say. Certain phrases can instantly raise concerns for hiring managers, no matter how strong your background is.

Below are the 10 things you should never say during a job interview, along with practical alternatives that leave a positive impression.

1. “I don’t know.”

It’s okay not to have every answer, but saying “I don’t know” without attempting to think through the question signals a lack of problem-solving ability.

✅ Better approach:

• “I haven’t encountered that exact situation, but here’s how I would approach it…"

• “While I don’t have direct experience, I’ve handled similar tasks like…"

This shows curiosity and adaptability.

2. “My previous boss/company was terrible.”

Speaking negatively about your past employer—even if you’re being honest—suggests poor judgement and raises concerns about professionalism.

✅ Better approach:

• Focus on what you learned and why you’re seeking new challenges, without criticizing individuals or organizations.

3. “What does your company do?”

This immediately signals a lack of preparation. Interviewers expect candidates to know the basics.

Before the interview, research:

• Company business model

• Products or services

• Market presence

• Recent news

• Your role’s impact within the organization

  
  

✅ Better approach:

Ask deeper questions like,

• “How does this role support the company’s strategic priorities?”

4. “I only care about salary.”

Compensation matters, but showing that money is the only motivator can be a red flag.

✅ Better approach:

• “Compensation is one part of the picture. I’m also excited about the scope of this role and opportunities for growth. My expected range is…”

This shows balance and maturity.

5. “I’m a perfectionist.”(or any cliché answer)

Hiring managers hear these clichés all the time, and they don’t add value.

✅ Better approach:

Share a real strength or weakness with a specific example and show how you’re improving.

6. “I don’t have any questions.”

This suggests a lack of curiosity or engagement.

✅ Better questions include:

• “What does success look like in this role?”

• “How does the team collaborate?”

• “What are the biggest challenges for this position?”

Thoughtful questions show genuine interest.

7. “I really need this job.”

Even if true, it can make you seem desperate and shift the tone uncomfortably.

✅ Better approach:

Express enthusiasm without pressure:

• “I’m very excited about this opportunity because…”

8. “That’s not in my job description.”

Rigid responses imply you may not be a team player.

✅ Better approach:

• “I’m open to helping where needed, as long as expectations are clear."

This shows flexibility—highly valued in modern workplaces.

9. “How soon can I take vacation?”

Asking about time off too early signals a focus on personal plans rather than the role.

• Bring this up only after an offer if you have a pre-existing commitment you must disclose.

10. Inappropriate jokes or overly personal comments

Maintain professional boundaries. Avoid humor that could be misinterpreted or personal details irrelevant to the job.

Job interviews are as much about communication and judgement as they are about qualifications. By avoiding these common pitfalls and focusing on thoughtful, professional dialogue, you significantly increase your chances of success.
