How to Pass the GravitHy Supply Chain Interview in 2026
The GravitHy DNA (TL;DR)
The 'Electrify France' initiative at GravitHy drives evaluation for candidates who can demonstrate practical, large-scale industrial execution. Interviewers assess a candidate's ability to navigate complex project lifecycles and contribute to tangible, impactful progress in green hydrogen.
The GravitHy 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 GravitHy interview outcomes, avoid these common traps:
- Suggesting a one-size-fits-all inventory policy (e.g., always use safety stock).
- Focusing on a single silo (e.g., only procurement or only logistics) rather than the entire chain.
- Relying solely on simplistic forecasting methods without considering market dynamics.
- Overlooking critical industrial factors like proximity to customers, feedstock availability, or energy infrastructure.
Test Yourself: Real GravitHy Questions
Three real prompts pulled from our database.

Frequently asked questions
How long does the GravitHy 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 GravitHy?
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 GravitHy?
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.
