Job interviews are stressful enough and there will likely come a time when you cannot answer a question. Rather than assume that saying “I don’t know” will make you look unprepared or unqualified, think more about how you say it. Delivery matters and admitting you do not know something can demonstrate self-awareness, honesty, and problem-solving ability—traits every employer values.

When It’s Okay to Say “I Don’t Know”
When You Truly Don’t Know
If you are asked a question that’s completely outside your experience or knowledge base, it’s better to admit it than to guess wildly. Faking an answer can come across as dishonest or even arrogant—and if you encounter a follow up question testing your expertise, you could wind up in a truly challenging interview situation.
When the Question Is Hypothetical or Unusual
Sometimes interviewers ask curveball questions to test your thinking. If you are not sure how to respond, it is okay to say, “That’s a great question—I haven’t encountered that scenario before, but here’s how I would approach it.” Sketch out your response step by step, and if it is a behavioral question, consider the STAR method.
When You are Clarifying a Concept
If you do not recognize a technical term or acronym, ask for clarification rather than pretending to understand. Employers appreciate curiosity and a desire to learn; simply nodding along may lead your interviewer to even more complex questions about an area you are unfamiliar with.
How to Say “I Don’t Know” — The Right Way
Saying “I don’t know” is not the end of the world—it’s the beginning of a great follow-up. Here’s a framework that keeps the conversation productive:
Be Honest but Strategic
Instead of bluntly saying “I don’t know,” try:
- “That’s not something I’ve worked with directly, but I’d love to learn more.”
- “I haven’t had hands-on experience with that yet, but here’s how I would approach learning it…”
Show How You Would Figure It Out
Explain your process. Are you the type to ask a mentor, dig into documentation, or experiment and troubleshoot?
- “When I run into something unfamiliar, I usually start by reviewing online journals to see what the current research is or reaching out to someone who has handled something similar.”
This shows resourcefulness and initiative.
Connect It to What You Do Know
If the question relates to something related to your experience, bridge the gap:
- “While I have only used a similar program in my classwork, I have worked extensively with this through group and independent projects—so I imagine I could pick it up quickly.”
Turn It Into a Strength
Saying “I don’t know” can actually highlight your growth mindset—especially if you follow it up with curiosity or a question of your own:
- “I’m not familiar with that framework—do you use it often here?”
This not only keeps the conversation going, but shows you’re engaged and eager to learn.
TLDR: No one expects you to know everything—especially in a first interview. What employers really want to see is how you handle uncertainty. If you stay calm, curious, and honest, even your “I don’t know” moments can leave a great impression.
