The Galp DNA (TL;DR)
Galp's energy transition roadmap requires candidates who quantify operational trade-offs across downstream retail products like Tus Tarjetas Mundo Galp. Interviewers measure whether candidates explicitly name rejected alternatives when evaluating capital allocation projects.
The Galp 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 Galp interview outcomes, avoid these common traps:
- Focusing too much on team efforts without detailing personal actions.
- Ignoring the dynamic nature of routing (e.g., traffic, last-minute changes).
- Prioritizing only one factor (e.g., cost) without adequately addressing the others.
- Focusing only on transportation costs without considering labor, real estate, taxes, or proximity to demand/supply points.
Test Yourself: Real Galp Questions
Three real prompts pulled from our database.
Type · Optimization Intuition
Explain the concept of linear programming to someone unfamiliar with it. Provide an example of how it could be used to optimize fuel blending at a refinery.
Type · Case Study
Galp is considering expanding its renewable energy infrastructure (e.g., solar farms, wind turbines) in Brazil. How would you approach designing the supply chain network for sourcing components, managing installation logistics, and ensuring ongoing maintenance parts availability?

Sample answers
What a strong answer to these Galp interview questions shows.
In supply chain management, we often face trade-offs between cost, service level, and environmental impact (CO2 emissions). Describe a situation where you had to balance these competing priorities. How did you make the decision?
A strong answer shows: Identifies specific examples of competing priorities.; Explains the methodology used to evaluate trade-offs (e.g., total cost analysis, scenario planning).; Demonstrates a balanced approach considering all factors..
Explain the concept of linear programming to someone unfamiliar with it. Provide an example of how it could be used to optimize fuel blending at a refinery.
A strong answer shows: Clearly defines objective function, decision variables, and constraints.; Provides a concrete and relevant example (e.g., refinery blending, fleet routing).; Highlights the benefits of using LP over heuristic methods..
Frequently asked questions
How long does the Galp 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 Galp?
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 Galp?
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.
