Commercial Marketing interview prep.

Hires wholesale + retail fuel marketers, product traders, supply + optimisation analysts, wholesale account managers, terminal commercial leads, branded jobber / distributor managers, and lubricants / specialty marketers across refiners, integrated majors, independent marketers, and large jobbers.

What interviewers look for

  • Can the candidate price a barrel from refinery gate to rack to net-back, decomposing every line in between?
  • Do they understand product cracks + basis + location economics - not just headline crack spread?
  • Are they fluent in the RIN + LCFS + RFG / RBOB / CARB / ULSD regulatory stack and the P&L impact of each?
  • Can they structure a wholesale supply contract - tenor, volume firmness, indexation, brand, exchange + sleeve?
  • Do they think in margin layers - refinery gate / wholesale rack / dealer tank wagon / street price - and net-back economics?
  • Are they grounded in retail + branded marketing - image programs, brand fees, c-store + non-fuel margin, commission vs lessee-dealer economics?
  • Long-game fit - marketer / supply analyst / trader / commercial manager / VP marketing trajectory in a downstream commercial book?

Behavioural questions to expect

  1. Walk me through your background + downstream commercial / marketing experience.

    What it tests: Story arc - entry path, channel + product exposure, margin + supply work, why downstream commercial. WHY: interviewers want to map the candidate against rack + wholesale + retail + trading rhythm fast.

  2. Tell me about a supply contract, rack pricing call, or commercial program you've worked on.

    What it tests: Commercial decision-making + margin reasoning - not just process narration. WHY: senior interviewers want structured trade-off thinking, not chronology.

  3. Why downstream commercial / marketing vs trading, refining, or midstream commercial?

    What it tests: Authentic alignment - margin layer ownership, channel work, mix of trading + marketing + program design.

  4. Why this channel / product mix - branded wholesale vs unbranded rack vs retail vs specialty?

    What it tests: Specificity. Generic 'I like fuels' answers fail. Channel + product is a real distinction.

  5. Why this firm?

    What it tests: Real homework - PADD footprint, branded network, RIN / LCFS posture, retail program - not name-drop.

  6. What's your read on our commercial footprint + channel position?

    What it tests: Industry literacy - terminal + retail + branded network, PADD footprint, competitive position.

  7. Tell me what you understand about our wholesale + retail + RIN strategy.

    What it tests: Commercial / financial fluency - margin posture, branded program direction, RIN + LCFS strategy.

  8. Walk me through how you'd price a barrel from our refinery gate to a customer's rack pickup.

    What it tests: Net-back craft - posted rack vs net-back decomposition - blendstock, RIN, LCFS, freight, brand, exchange.

Technical concepts to master

Rack + wholesale pricing mechanics

Rack price + posting cycle
Terminal rack price posted daily - typically 6 PM local for next-day pickup; branded + unbranded grades posted separately.
OPIS + Argus index pricing
Independent reporting agencies publishing rack + spot price benchmarks - OPIS dominates US rack, Argus dominates spot + globally.
Spot vs rack vs contract
Spot = bulk transport at refinery / pipeline / terminal (40 kbbl+); rack = truck pickup at terminal (8 kgal); contract = negotiated volume + index.
Exchange agreements + time-swaps
Exchange = swap product at different locations to reach a customer; time-swap = borrow + repay same product later (with carry).

RIN + LCFS + renewable fuels stack

RFS + RVO (Renewable Volume Obligation)
Federal Renewable Fuel Standard mandates obligated parties (refiners + importers) blend or buy RINs to cover obligation.
RIN categories - D3 / D4 / D5 / D6
D3 = cellulosic, D4 = biomass-based diesel, D5 = advanced biofuel, D6 = conventional ethanol; nested obligation hierarchy.
RIN bank + vintage carry
Up to 20% of prior-year RVO can be covered with current-year RINs; RIN bank manages timing + price exposure.
LCFS (California + Oregon + Washington)
State Low Carbon Fuel Standard - fuels with Carbon Intensity (CI) above benchmark generate deficits; below benchmark generate credits.

Wholesale + branded contract structures

Branded supply contract (jobber / distributor)
Long-term branded supply to jobber / distributor - 5-10 years, indexed to OPIS rack-plus or NYMEX-plus, brand fee + image program co-invest.
Unbranded rack supply
Daily rack supply to unbranded distributors + jobbers; spot-style pricing, no brand fee, no image obligations.
Commission marketer + lessee dealer + open dealer
Commission marketer = brand owner controls retail pump price + receives margin; lessee dealer = leases site, sets own pump price; open dealer = independent operator.
Throughput agreement + terminal storage
Contract for terminal throughput + storage - per-gallon fee + minimum throughput obligation.

Retail + non-fuel margin economics

Street price + retail fuel margin (CPG)
Pump price minus delivered cost = retail fuel margin in cents per gallon (CPG); market + competitor watch driven.
Volume vs margin trade-off
Lower pump price -> higher volume + lower CPG vs higher pump price -> lower volume + higher CPG; convergent gross-profit-per-day target.
Inside-the-store / c-store basket
Non-fuel revenue + margin from c-store - tobacco, beverages, snacks, foodservice; foodservice growing share.
Foot traffic + same-store metrics
Same-store-fuel-volume + same-store-inside-sales + same-store-fuel-margin = canonical retail KPIs disclosed quarterly.

Practical drills

  • An unbranded jobber wants to lift gasoline (CBOB E10) at your Group 3 terminal. OPIS Group 3 unbranded rack = 245 cpg. Estimated D6 RIN cost = 8 cpg. Pipeline + terminal in / out = 6 cpg. Brand differential N/A (unbranded). Customer freight = 4 cpg (their cost). Walk through the net-back to refinery gate + how you'd think about the deal.
  • You're an obligated party with an annual D4 (biomass diesel) RIN obligation of 50M RINs. You can (a) blend renewable diesel in-house at your terminals (CI benefit + RIN generation + 45Z PTC), (b) buy separated D4 RINs on the open market, (c) carry deficit forward against next year's bank. Forward D4 RIN strip = $1.50; in-house renewable diesel blend cost = $0.10 / gal premium net of RIN + 45Z; LCFS credit value (CA volumes) = $75 / tonne. Walk through the decision.
  • A 25-site branded jobber in the sector wants a 7-year branded supply renewal. Current contract = OPIS rack-plus 2 cpg + 1.5 cpg brand fee + 5-year image program co-invest. Competitor is offering them a swap to a different branded supplier at OPIS rack-plus 1.5 cpg + lower brand fee + faster image refresh. Walk through how you'd structure your renewal counter.

Smart-question anchors

  • Channel mix + branded posture - branded vs unbranded volumes, jobber + distributor network direction
  • PADD footprint + asset position - terminals + retail concentration, recent footprint shifts
  • RIN + LCFS posture - obligation management, renewable diesel investment, 45Z PTC capture
  • Retail program direction - company-op vs dealer vs commission marketer mix, c-store + non-fuel program
  • Trading + supply optimisation - in-house trading desk, exchange + time-swap activity, hedging discipline
