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
Probe bench formulation depth: hydrocolloid and emulsifier selection, water activity and pH targets, accelerated shelf life design, thermal process validation, and pilot plant scale-up trial protocols.
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 levers and shelf life study designs, with reasoned Aw, pH, and Fo targets tied to product stability.
02
Evaluation factor
Results that went somewhere
25% weight
Ask which SKUs they took from bench to launch, cost per kilo savings, clean label reformulations, or sensory panel results that changed a gold standard.
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 launched products or reformulations with volumes, margin impact, and the sensory or shelf life data that unlocked sign-off.
03
Evaluation factor
Troubleshooting and reproducibility
25% weight
Test how they chase off-notes, syneresis, texture drift, or microbial failures: challenge testing, ingredient lot variation, and replicating a plant trial back at bench scale.
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 defect investigation, isolating variables systematically and confirming the fix held across multiple production lots.
04
Evaluation factor
Documentation and collaboration
15% weight
Check spec and documentation habits: formulation cards in PLM, HACCP plans, allergen and nutrition labelling, plus how they brief operations and QA during a line trial.
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 audit-ready specs and labelling files, and describes working alongside procurement, QA, and plant operators through commissioning trials.
