How would you implement a Sales and Operations Planning (S&OP) process at Gigaton, considering our unique position in the circular economy and the need to balance inbound battery supply with downstream processing and material sales?
How to Pass the Gigaton Supply Chain Interview in 2026
The Gigaton DNA (TL;DR)
Deploying 'Control for Energy Intensive Industries' requires evidence of managing thermal trade-offs with explicit denominator metrics rather than abstract efficiency claims.
The Gigaton Interview Loop
Your onsite loop will typically consist of 5 rounds.
- 1
Round 1
Recruiter ScreenMotivation, operations background, supply chain interest. - 2
Round 2
Operations CaseEnd-to-end supply chain optimization, bottleneck diagnosis, network design. - 3
Round 3
Forecasting & PlanningDemand planning, S&OP, inventory optimization, working with statistical and ML forecasts. - 4
Round 4
OptimizationLinear programming intuition, route optimization, facility location, trade-offs between cost/service/CO2. - 5
Round 5
Behavioral / LeadershipPast evidence of ownership, influence, resolving conflict.
The Danger Zone: Top Reasons Candidates Fail
Based on our database of Gigaton interview outcomes, avoid these common traps:
- Focusing solely on personal career goals without demonstrating genuine interest in Gigaton's impact.
- Failing to explain the root cause of the conflict or the specific steps taken to mediate.
- Not addressing the inventory management aspect specifically for processing capacity or materials.
- Focusing only on forecast accuracy metrics without discussing the 'why' behind deviations.

Operations Case
3- 2
Type · case
Imagine Gigaton is experiencing a surge in demand for its battery recycling services, leading to bottlenecks at our collection hubs and processing facilities. How would you diagnose the root causes of these bottlenecks and propose a phased approach to scale operations effectively while minimizing CO2 emissions? - 3
Type · case
Gigaton aims to expand its battery collection network across North America. Describe the key factors you would consider when designing this network, including facility location, transportation modes, and inventory strategy, to balance cost, service levels, and CO2 footprint. - + 1 more questions in this round (sign up to unlock)
3
Forecasting & Planning
3- 4
Type · case
Gigaton's battery collection volume can be highly variable due to factors like EV sales cycles and seasonal trends. How would you approach demand forecasting for our collection services, and what methods would you use to manage inventory of processing capacity and key materials? - 5
Type · case
Describe your experience working with statistical and ML-based demand forecasts. How do you evaluate their accuracy, and what steps do you take when the forecast deviates significantly from actuals, especially concerning our battery material inputs? - + 1 more questions in this round (sign up to unlock)
4
Optimization
3- 6
Type · case
Explain your intuition behind linear programming. If we wanted to optimize the routing of our collection trucks to minimize fuel consumption and CO2 emissions while meeting pickup windows, what would be the key decision variables, objective function, and constraints? - 7
Type · case
Gigaton is considering opening a new battery processing facility. What are the critical trade-offs between locating a facility closer to battery sources (potentially higher inbound logistics cost but faster processing) versus closer to material buyers (potentially lower outbound logistics cost but longer inbound transit)? How would you evaluate these options? - + 1 more questions in this round (sign up to unlock)

Behavioral / Leadership
3- 8
Type · behavioral
STARTell me about a time you had to influence a stakeholder or team outside of your direct control to adopt a new supply chain process or technology. What was the situation, your approach, and the outcome? - 9
Type · behavioral
STARAt Gigaton, our rapid scaling often forces us to integrate new battery chemistry processing streams into existing facilities before the infrastructure is fully optimized. Describe a time you had to manage the operational transition of a new, high-volume material stream while maintaining the throughput of legacy processes. How did you identify the specific physical constraints, and what was your process for sequencing the integration to avoid a net decline in facility efficiency? - + 1 more questions in this round (sign up to unlock)

Frequently asked questions
How long does the Gigaton interview process take?
Most candidates spend between 4 and 8 weeks from recruiter screen to offer. The onsite loop itself runs in a single day or is split across two half-days, with debrief and offer typically within 5 business days after.
How should I prepare specifically for Gigaton?
Focus on three things: (1) the company DNA shown above - what they actually grade for, (2) the rounds in your loop, especially the round most candidates underestimate, and (3) drilling on the question types in this guide using a structured framework like CIRCLES or STAR.
Does this apply to engineering or design roles at Gigaton?
The DNA stays the same - what changes is the round mix. SWE candidates face coding screens instead of Product Sense; designers face portfolio reviews and design exercises. The "what they value" and behavioral signals carry across all functions.
