How do you handle situations where the evidence is inconclusive or contradictory?

Hiring managers ask this question to see how you think critically and methodically when evidence doesn’t clearly point to one conclusion. You need to explain that you carefully evaluate all data, investigate contradictions step-by-step, and clearly report any uncertainties or limitations in your findings.

Example: When evidence doesn’t paint a clear picture, I focus on carefully reviewing all details and considering alternative explanations. It’s important to stay objective and avoid jumping to conclusions. I then document my findings clearly, highlighting any uncertainties so that investigators understand the limitations. For example, in a past case where samples conflicted, thorough re-examination and clear communication helped guide the next steps effectively.
