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 bench and pilot work: formulation trials, sensory panel design, water activity and pH hurdle testing, accelerated shelf life protocols, texture analysis, thermal process validation.
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 trials with controls and variables, cites Aw, pH, Brix targets, and explains why each analytical method was chosen.
02
Evaluation factor
Results that went somewhere
25% weight
Probe products that reached retail or foodservice: SKUs launched, reformulations for salt or sugar reduction, cost-down projects, allergen removal, and the volumes or margins affected.
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
Points to named launched products, quantifies yield, cost or shelf life gains, and describes the factory scale-up they supported.
03
Evaluation factor
Troubleshooting and reproducibility
25% weight
Test how they handled batch failures: emulsion splits, syneresis, off-notes, microbial spoilage or out-of-spec CCP readings, plus root cause work and pilot-to-line 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 real spoilage or texture failure, the hypotheses tested, corrective action taken, and how recurrence was prevented.
04
Evaluation factor
Documentation and collaboration
15% weight
Assess command of specifications, HACCP plans, BRCGS or SALSA audit evidence, labelling and nutrition declarations, and daily work with NPD, procurement and production teams.
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
Describes writing specs and HACCP documentation that survived audit, and shows credible give-and-take with buyers, suppliers and line supervisors.
