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 how they design bench trials: ingredient functionality, factorial or DOE screening of hydrocolloids and emulsifiers, pilot plant scale-up factors, accelerated shelf life and water activity testing.
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 formulation variables tested, links bench recipes to pilot line parameters, and justifies shelf life protocols with aw and micro data.
02
Evaluation factor
Results that went somewhere
25% weight
Probe products that reached retail or foodservice: SKUs launched, brief to launch timelines, cost per kilo achieved, reformulation for HFSS, salt or sugar reduction targets.
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
Cites named launched lines with volumes, margin or cost savings delivered, and reformulation targets hit without sensory scores dropping.
03
Evaluation factor
Troubleshooting and reproducibility
25% weight
Test how they diagnose failures: syneresis, retort over-processing, off-notes after eight weeks, batch to batch inconsistency between bench, pilot, and third party factory runs.
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 specific failure, isolates the causal variable methodically, and describes the fix plus how they verified repeatability across batches.
04
Evaluation factor
Documentation and collaboration
15% weight
Assess specification discipline and cross-functional work: product specs, QAS documents, allergen and nutrition labelling, sensory panel briefs, and handovers to procurement, marketing, and co-manufacturers.
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
Produces accurate specs and label data unaided, references relevant labelling regulation, and shows how they aligned buyers, factory technical, and chefs.
