Technical practice
How would you test an assessment that is fluent, well-cited and internally coherent but wrong?
What to coverPreparation suggestion: Trace each consequential claim to its cited evidence and check whether the evidence supports the inference, not just the wording. Explain how you would test alternative interpretations and record uncertainty where the sources cannot settle the question.
How would you find the assumption doing the most work in a conclusion?
What to coverPreparation suggestion: Identify which assumption would most change the conclusion if false, then propose a test that could disprove it. Look for evidence that should exist under the conclusion but is missing, while accounting for incomplete multi-source data.
How would you test poisoning and instructions embedded in material the system reads?
What to coverPreparation suggestion: Distinguish corrupted source content from an instruction attempting to redirect the system, and describe controlled tests for each. Assess whether the resulting conclusion or cited evidence changes, not merely whether the suspicious text is repeated.
What would saturation and probing reveal about the system?
What to coverPreparation suggestion: Describe how repeated, varied inputs could expose what the system reacts to or cause it to miss consequential evidence. Explain how you would measure both answer quality and information revealed to an adaptive adversary.
How would you demonstrate that a defence holds after discovering an attack?
What to coverPreparation suggestion: Retest the original failure and variations that the defence has not seen, using explicit failure criteria. Discuss the trade-off between blocking attacks and preserving the system's ability to use legitimate source material.
How would you evaluate correctness when reviewers cannot inspect every output?
What to coverPreparation suggestion: Explain how held-out ground truth and scoring by question class could reveal failures hidden by an aggregate score. Address how you would select cases and interpret results when reliable ground truth is limited.
How would you detect unstable performance or drift?
What to coverPreparation suggestion: Compare repeated runs on the same cases and track results by question class over time. Distinguish run-to-run variance from a sustained change, and explain what evidence would justify investigating either.
How would you distinguish a real flaw from a plausible-sounding critique?
What to coverPreparation suggestion: Require a critique to identify a consequential claim, specify what would falsify it and connect the objection to evidence. Explain how you would handle objections that sound persuasive but cannot yet be verified.
Why might self-play results fail to transfer to this domain?
What to coverPreparation suggestion: Address partial observability, adaptive adversaries, an uncertain simulator and outcomes that may remain unobservable for years. Discuss what limited evidence could still be useful without treating a simulated reward or equilibrium as proof of real-world performance.
How would you test whether machine assessments improve throughput but worsen human judgment?
What to coverPreparation suggestion: Propose a controlled comparison of decisions made with and without the assessment, measuring reasoning quality as well as speed. Account for anchoring on fluent but incorrect outputs and for humans retaining final judgment.
Behavioural practice
Tell me about a time you challenged a conclusion others found convincing.
What to coverPreparation suggestion: Use a real situation, your action and the result. Focus on the assumption or missing evidence you identified, how you made the case against resistance and what the evidence ultimately showed.
Describe a time you designed a test that could disprove your own preferred idea.
What to coverPreparation suggestion: Explain the situation, the falsification criterion you chose, the action you took and the result. Be clear about how you responded if the outcome was inconclusive or contradicted your expectation.
Give an example of evaluating work while maintaining an independent perspective.
What to coverPreparation suggestion: Describe the situation, how you avoided inheriting the team's assumptions and what you did to test your concerns fairly. State the result without presenting disagreement itself as evidence of a flaw.
Tell me about a time you communicated a consequential uncertainty to decision-makers.
What to coverPreparation suggestion: Set out the situation, what was and was not known, the action you took to communicate it and the result. Explain how you avoided overstating confidence while leaving the final judgment with the people responsible for it.
