Why pre-screen packaging design engineers before the technical interview
Packaging failure is delayed and expensive. A pack that performs in the laboratory can arrive damaged after a real distribution route with different handling, stacking and temperature, and the cost lands as returns and complaints months after sign-off. Engineers who have investigated field damage design differently, because they have seen what actually happens between the line and the customer. A short screen asks about that investigation, which separates them from candidates whose experience stopped at approval.
What actually matters when screening Packaging Design Engineer candidates
- 01
Technical depth
Check command of substrate selection and structural design: corrugated flute and board grades, ECT versus burst, ArtiosCAD or Esko dielines, thermoform gauge, ASTM D4169 and ISTA 3A protocols.
- 02
Work that shipped
Ask for packs that reached production: SKU counts, tooling and dieline releases, cube or material savings, damage rate reductions, and the co-packer or converter they qualified with.
- 03
Diagnosis under uncertainty
Probe how they chased down field failures: crush in transit, seal leaks, line jams at the case packer, using drop test video, incident data and pilot runs.
- 04
Working across the org
Assess work with procurement, marketing, converters and plant line operators: resolving graphics versus structure conflicts, trial runs, sustainability targets, and PPWR or recyclability compliance pressure.
Pre-screening questions to ask Packaging Design Engineer candidates
12 questions grouped by what they test. Ask the same set in every screen and score answers on a consistent scale, or send them as an async video screen and compare answers side by side.
Materials and structure
3 questions01What experience do you have with materials testing and selection for packaging?
Listen forNamed materials with the property they were chosen for, such as compression strength, barrier or moisture performance, and how it was tested.
Materials selected on cost or appearance alone, or specifications taken from a supplier with no independent testing.
02How familiar are you with developing construction specifications for packaging?
Listen forSpecifications they wrote with tolerances and board grades named, detailed enough for a converter to produce it consistently.
Specifications described as drawings handed to a supplier, with no tolerance or material grade defined.
03What is your experience with design and manufacturing software for packaging?
Listen forStructural design tools used to produce cutting formes and dielines, rather than graphics software with no structural work.
Software experience that turns out to be artwork only, with no structural design responsibility.
Packs that shipped
3 questions04Can you describe a packaging design project you saw through to production?
Listen forA pack that shipped with volume stated, plus what changed between the approved design and what the converter actually produced.
Concepts presented as delivered work, or no involvement after the design was approved.
05Have you designed packaging for fragile or sensitive products?
Listen forProtection designed against a specific hazard with drop and vibration testing described, and the transit route considered in the design.
Protection added by feel, or no transit testing before the pack went to market.
06Do you have experience designing packaging for shipping and distribution?
Listen forPallet efficiency, stacking strength and the realities of the route considered, including handling the design cannot control.
Designs optimised for shelf appearance with no attention to pallet fit or stacking through the supply chain.
Diagnosing damage
3 questions07Can you describe a time you had to solve a difficult problem with a package design?
Listen forA damage pattern investigated to a cause, with route analysis or returned samples examined rather than protection simply increased.
Problems solved by adding material, with no diagnosis of where in the chain the damage occurred.
08Do you have experience evaluating and improving existing packaging designs?
Listen forA redesign driven by evidence such as damage rates or line stoppages, with the measured result after the change.
Redesigns driven by appearance, or improvements claimed with no damage or cost figure attached.
09Can you tell me about a time you used analysis to inform a package design?
Listen forTesting or simulation used to make a decision, with the result compared against how the pack actually performed in the field.
Analysis reported with no field comparison, or simulation used to justify a decision already made.
Line and procurement
3 questions10Are you familiar with automated production and packing processes?
Listen forLine speed and equipment constraints understood, with a design change forced by how the pack behaved on automated equipment.
Designs handed to production with no line trial, or no awareness of how a pack performs at speed.
11Do you have experience working with suppliers and vendors for packaging materials?
Listen forDirect technical conversations with converters, including qualifying a second source or rejecting material against specification.
Supplier contact routed entirely through procurement, with no technical discussion of process capability.
12How do you ensure a design protects the product while remaining cost-effective?
Listen forCost per unit weighed against damage rate, with a case where they argued for more material because the returns cost more.
Optimises cost with no damage data, or accepts a material reduction without testing the effect on protection.
How to score responses
Score every candidate on the same four criteria immediately after the screen. At this stage you are shortlisting for panel interviews, not making the final call.
Technical depth
35%5Names board grades, closure styles and cushioning materials by spec, and explains why each was chosen over alternatives.
Work that shipped
30%5Cites specific launched packs with measured outcomes: pallet cube gained, cost per unit cut, damage claims down.
Diagnosis under uncertainty
20%5Walks through a real damage investigation from claim data to root cause and validated design change.
Working across the org
15%5Describes negotiating brand, cost and line speed constraints with named partners and reaching a pack everyone signed off.
A pack that passes in the laboratory can still arrive damaged after a real route, months after sign-off. A one-way video screen asks about the failure investigation.

Process basics
How long should a pre-screening round for a packaging engineer take?
Fifteen minutes across eight to ten questions, answered async. Enough to separate structural engineering from graphic design, confirm transit testing experience, and hear one field failure investigation.
What should the screen establish beyond design software?
Whether their packs ran on a line and survived a real route. Computer-aided design skill is common; understanding how a pack behaves at speed on automated equipment, and after being stacked on a pallet for three weeks, is not.
Evaluating answers
What is the strongest signal when screening a packaging engineer?
A pack that failed after launch. Engineers who have handled it describe the damage pattern, what the route analysis showed, and the change they made. Candidates whose work stopped at approval describe test results instead.
How do I judge sustainability claims?
Ask what the change cost in protection or in cost per unit. Credible answers include a trade-off and a measurement. Anyone describing a material substitution with no downside has either not measured it or not shipped it.
