Complete evaluation framework
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
Technique and experimental design
35% weight
Check depth in mammalian cell culture for food: myoblast or fibroblast isolation, serum-free media formulation, microcarrier or scaffold work, and stirred-tank or perfusion bioreactor design of experiments.
Evidence to listen for
Runs the assays and instruments themselves rather than describing what a team does
Designs experiments with controls, replicates, and a stated hypothesis
Knows what each technique can and cannot resolve
Understands the science, not only the protocol
Five-point scoring guide
1
Poor
Protocol follower with no experimental design; cannot justify controls.
2
Needs Improvement
Runs standard assays; designs experiments poorly or not at all.
3
Satisfactory
Competent at the bench with sound routine design.
4
Very Good
Designs rigorous experiments and understands the limits of each technique.
5
Excellent
Names specific cell lines, growth factor concentrations and DoE runs; explains why a media component was swapped and what it cost.
02
Evaluation factor
Results that went somewhere
25% weight
Probe outputs that moved a programme forward: doubling times achieved, cell densities per millilitre, cost per litre of media reduced, prototype tastings, or regulatory dossier data packages.
Evidence to listen for
Names projects where their results changed a decision, a process, or a product
States their own contribution rather than the group's
Has taken something from bench to a larger scale, a filing, or a publication
Knows what happened to the work after they handed it over
Five-point scoring guide
1
Poor
No results that went anywhere; work is entirely exploratory.
2
Needs Improvement
Contributed to projects but cannot say what their data changed.
3
Satisfactory
Real contributions; outcomes described loosely.
4
Very Good
Names results that changed a decision, with clear personal scope.
5
Excellent
Quantifies gains such as media cost dropping from dollars to cents per litre, and links data to a scale-up or filing decision.
03
Evaluation factor
Troubleshooting and reproducibility
25% weight
Test how they handle contamination events, differentiation failure, lot-to-lot variability in recombinant growth factors, and shear stress in bioreactors; ask what they changed to restore reproducibility.
Evidence to listen for
Treats a failed run as information rather than bad luck
Isolates reagent, instrument, operator, and biological causes systematically
Knows why a result failed to reproduce and can say when their own data was wrong
Keeps records good enough to diagnose from months later
Five-point scoring guide
1
Poor
Repeats failed runs unchanged; no diagnostic thinking.
2
Needs Improvement
Troubleshoots by substitution; cannot explain a reproducibility failure.
3
Satisfactory
Solid troubleshooting on familiar assays.
4
Very Good
Systematic isolation of causes, and honest about their own irreproducible results.
5
Excellent
Walks through a root cause investigation with controls and replicates, then describes the SOP or QC gate that stopped recurrence.
04
Evaluation factor
Documentation and collaboration
15% weight
Assess electronic lab notebook discipline, batch records, and how they work with bioprocess engineers, food safety and regulatory teams on FDA or FSANZ submissions.
Evidence to listen for
Keeps records to the standard the setting requires, whether that is GLP, GMP, or a defensible notebook
Writes up so someone else can repeat the work
Works with process, quality, or clinical colleagues rather than in a bench silo
Explains a result to a non-specialist without overclaiming
Five-point scoring guide
1
Poor
Records would not survive audit; work is not repeatable from them.
2
Needs Improvement
Documentation is thin; write-ups need heavy editing.
3
Satisfactory
Adequate records and write-ups; collaboration is limited.
4
Very Good
Audit-standard records and clear communication across functions.
5
Excellent
Keeps traceable records others can rerun, and cites concrete handoffs to process engineering or regulatory colleagues on shared timelines.
