Walk me through your CV.

What it tests: Story arc - technical training (ChemE / materials / chemistry / engineering MBA), customer + channel exposure, P&L exposure, why industrial chemicals sales now.

Tell me about a customer or account where you owned a measurable commercial outcome.

What it tests: Commercial thinking - customer strategy translated into spec-in, contract value, margin, share - not just a relationship anecdote.

Why chemicals + materials commercial sales - vs CPG sales, process engineering, technical service, or consulting?

What it tests: Authentic interest in the industrial-B2B sales craft - technical-sell, multi-year contract ownership, value-in-use economics, customer-plant fluency.

Why this product family - commodity vs specialty vs polymers vs advanced materials?

What it tests: Specificity. Generic 'I like chemicals' answers fail. Strong answers tie product economics to genuine commercial interest.

What it tests: Real homework - product portfolio, customer segments, recent strategic moves, sales culture, talent track record - not name-drop.

What is your read on our product portfolio and customer-segment mix?

What it tests: Industry literacy - product commodity / specialty mix, customer concentration, segment exposure, recent contract trajectory.

How would you describe our channel mix and regulatory + contract posture?

What it tests: Channel + regulatory fluency - direct vs distributor mix, contract architecture, REACH / TSCA exposure, regional regulatory differences.

Walk me through how you would build a value-in-use case for a customer who is asking for a 5% price reduction.

What it tests: Value-in-use + customer economics literacy - the candidate must reframe from kg-price to total-cost-of-ownership, quantify the customer's downstream economics (yield, downtime, scrap, energy, formulation efficiency), and land on a value-share argument. Cardinal sin is matching the price-down ask without the VIU diagnostic.

Commercial Sales interview prep.

Technical sales engineer / key account manager / business development manager / commercial director track at commodity chemicals, specialty chemicals, polymers, advanced materials, industrial gases, coatings, adhesives.

What interviewers look for

Can the candidate run a value-in-use case - total cost of ownership replacing kg-price - not just quote spot price?
Do they understand the spec-in + qualification cycle - R&D contact, lab + plant trial, PPAP / sample approval, SOP - and how long it takes?
Can they negotiate a multi-year contract - price-volume, indexation to feedstock or PPI, surcharge, take-or-pay, force majeure - with real rigor?
Are they channel-fluent - direct vs distributor vs tolling vs OEM-spec - and where margin actually sits?
Do they speak regulatory compliance - REACH, TSCA, GHS, SDS - as a sales enabler, not an afterthought?
Can they partner with R&D + technical service + supply - the cross-functional team that wins specs and protects them?
Do they read industrial customer economics - feedstock pass-through, downstream margin, capacity utilisation - to time the ask?

Technical concepts to master

Value-in-use selling + technical service

Value-in-use (VIU): Total economic value our product creates in the customer's process vs the next-best alternative - measured per unit of customer output, not per kg of input.
Next-best alternative: The realistic substitute the customer would deploy if our product were unavailable - another supplier, another chemistry, in-house production, no-substance reformulation.
Value-share logic: We capture a share - typically 30-50% - of the value our product creates over the next-best alternative; the rest stays with the customer to justify switching cost + sustained adoption.
Technical service as investment: Applications lab support, on-site trial coverage, joint development, formulation tuning - sized vs customer lifecycle revenue, not free of charge.

Spec-in + qualification cycle

Spec-in: Getting our product or grade written into the customer's bill of materials, formulation spec, or approved-vendor list so that any change requires customer requalification.
Qualification cycle - lab + plant + PPAP: Sample submission with spec sheet + SDS -> lab trial (customer R&D validation) -> plant trial (commercial-scale validation) -> PPAP (auto) or formal qualification doc -> SOP (start-of-production).
Decision-maker map - R&D, procurement, plant, regulatory: R&D = technical champion + spec-writer; procurement = commercial gate + multi-source policy owner; plant / production = trial validator + reliability gate; regulatory = REACH / TSCA / SDS gate.
PPAP (Production Part Approval Process): Auto-industry formal qualification protocol - 18 elements covering material, process, capability; required before any auto OEM supply.

Contract architecture + indexation + force majeure

Indexation - feedstock + PPI: Contract clause tying price to a published index - naphtha, ethylene, propylene, monomer, PPI by chapter - with a defined formula, lag, and floor / ceiling.
Surcharge - energy + freight + carbon: Variable add-on to base price for movements in energy, freight, or carbon cost beyond a defined threshold.
Take-or-pay + minimum volume: Customer commits to buy a minimum volume per period or pay a shortfall payment - typically 80-90% of contracted volume.
Force majeure + supply allocation: Clause excusing performance during defined events (hurricane, plant outage, regulatory shutdown, transport disruption) + how allocation across customers is handled.

Channel + distributor management + REACH / TSCA regulatory

Direct vs distributor economics: Direct = full gross margin minus cost-to-serve; distributor = realised margin minus 8-20% distributor margin minus lower cost-to-serve.
Distributor management - selection + co-sell + margin floor: Distributor selection (technical capability, regional fit, credit, exclusivity), co-sell programme (joint visits, technical training, lead sharing), price floor protection.
REACH (EU regulation): Registration, Evaluation, Authorisation + Restriction of Chemicals - EU regime requiring registration of substances above 1 tpa + authorisation of substances of very high concern (SVHC).
TSCA (US) + K-REACH + China REACH: TSCA = US Toxic Substances Control Act, parallel substance inventory + new chemical notification; K-REACH (Korea) + China REACH (CIETSAR) = regional analogues.

Practical drills

Your specialty additive sells at $5,000 / ton. Customer is a coatings formulator using 200 tons / year. The additive replaces a $3,000 / ton commodity alternative but raises customer yield from 92% to 96% on a $20 / kg finished coating. Customer procurement is asking for 10% price reduction. Walk through the VIU case + your response.
An auto OEM is launching a new EV battery platform in 30 months. You sell a polymer that competes with the incumbent on thermal-runaway protection. The incumbent has been specced for 8 years. Walk through your spec-in strategy.
Customer is a packaging converter buying 5,000 tons / year of polymer at $1,500 / ton on annual contract. Naphtha feedstock has moved 30% in the last year. Customer wants a 3-year contract with a 5% price reduction. Walk through your contract architecture + counter-proposal.

Smart-question anchors

Product portfolio + commodity / specialty / advanced materials mix - where the margin sits + where growth comes from
Customer-segment exposure - auto, electronics, packaging, construction, healthcare, energy - and segment-specific cycle
Channel mix - direct vs distributor vs tolling vs OEM-spec - and recent channel shifts
Contract architecture + indexation posture - spot vs multi-year %, feedstock pass-through cleanliness
Spec-in + qualification footprint - which OEMs + processors carry firm grades on approved-vendor lists
