What do you say when you do not remember a detail about a case?

• A. I have no idea
• B. I do not recall
• C. Not sure
• D. I refuse to answer

Answer: (B)

When you can’t remember a detail from a case, you should communicate a memory gap clearly and professionally. Saying “I do not recall” does just that: it accurately states you don’t remember the detail without guessing. It preserves credibility because you’re not asserting false information, and it keeps the door open to verifying the detail later by reviewing notes or records.

That phrase is preferable to the casual or evasive options. Saying “I have no idea” suggests a lack of effort or unwillingness to check the facts, which undermines reliability. “Not sure” is informal and vague, leaving the interviewer unsure of your exact memory status. “I refuse to answer” can imply non-cooperation or withholding information and can create procedural or ethical issues.
