What to assess and how to score it
Review the evidence signals before interviewing. Then use the anchored descriptions—not instinct alone—to choose the score that best matches each answer.
01
Evaluation factor
Theoretical command
35% weight
Check command of variational circuits, parameter-shift gradients, barren plateaus, quantum kernels and data encoding choices; ask why amplitude encoding was chosen over angle encoding on a real problem.
Evidence to listen for
Explains the underlying theory at the level the role demands, and can go a layer deeper when pushed
Knows which results are established and which are contested
Distinguishes their own contribution from the field's
Comfortable saying where the theory runs out
Five-point scoring guide
1
Poor
Recites terminology without understanding; cannot go one layer deeper.
2
Needs Improvement
Surface familiarity; conflates established results with speculation.
3
Satisfactory
Solid grasp of the core theory; thin at the frontier.
4
Very Good
Strong command; separates settled results from open questions.
5
Excellent
Explains barren plateau mitigation, kernel expressivity limits and encoding trade-offs precisely, citing specific papers and their known failure modes.
02
Evaluation factor
From theory to hardware or code
30% weight
Probe code they shipped in Qiskit, PennyLane, Cirq or TensorFlow Quantum, including transpilation, error mitigation passes and runs on IBM, IonQ or Rigetti backends.
Evidence to listen for
Has built, simulated, or run something real, not only published about it
Knows the gap between the idealised model and the actual apparatus or system
Names the practical constraint that dominates in real conditions
Can describe a result that did not match prediction
Five-point scoring guide
1
Poor
Purely theoretical; no contact with implementation.
2
Needs Improvement
Some exposure but unaware of practical constraints.
3
Satisfactory
Has implemented work; understands the main real-world limits.
4
Very Good
Strong practical record; articulate about theory-versus-reality gaps.
5
Excellent
Names circuits run on real QPUs, with qubit counts, shot budgets, mitigation applied and honest comparison against classical baselines.
03
Evaluation factor
Research judgement
20% weight
Assess how they decide a quantum approach is worth pursuing: ask when they abandoned a QML model because a classical baseline matched or beat it.
Evidence to listen for
Chooses problems by tractability and value, not novelty alone
Knows when to abandon a line of work
Reads and evaluates others' results critically
Can say what would falsify their own approach
Five-point scoring guide
1
Poor
Chases novelty; no sense of tractability or when to stop.
2
Needs Improvement
Weak problem selection; persists past the point of value.
3
Satisfactory
Reasonable judgement within a defined programme.
4
Very Good
Selects problems well and knows when to abandon a line.
5
Excellent
Describes killing a promising line after benchmarking, articulating where quantum advantage claims break down under noise and sampling cost.
04
Evaluation factor
Explaining it to non-specialists
15% weight
Test how they brief product leads or funders who lack physics training, translating hybrid quantum-classical results and hardware roadmaps without overselling near-term advantage.
Evidence to listen for
Explains the work to an engineer, an executive, or a funder without either mystifying or dumbing it down
Writes clearly
Collaborates across disciplines
Makes the case for resources in terms the audience cares about
Five-point scoring guide
1
Poor
Cannot communicate outside their specialism.
2
Needs Improvement
Explanation is either impenetrable or hollow.
3
Satisfactory
Adequate with technical peers; less effective with lay audiences.
4
Very Good
Explains clearly to specialists and non-specialists alike.
5
Excellent
Explains noise limits and timelines in plain terms, using clear analogies, and separates demonstrated results from speculative claims.
