The Rebaba DNA (TL;DR)

Recruiters at this Swedish Circular Battery Company test standard battery management logic alongside real-world hardware constraints. Passing requires detailing second-life battery degradation metrics and explicitly naming the trade-off you rejected during battery pack telemetry architecture.

The Rebaba Interview Loop

Your onsite loop will typically consist of 5 rounds.

1
Round 1
Recruiter Screen
Motivation, operations background, supply chain interest.
2
Round 2
Operations Case
End-to-end supply chain optimization, bottleneck diagnosis, network design.
3
Round 3
Forecasting & Planning
Demand planning, S&OP, inventory optimization, working with statistical and ML forecasts.
4
Round 4
Optimization
Linear programming intuition, route optimization, facility location, trade-offs between cost/service/CO2.
5
Round 5
Behavioral / Leadership
Past evidence of ownership, influence, resolving conflict.

The Danger Zone: Top Reasons Candidates Fail

Based on our database of Rebaba interview outcomes, avoid these common traps:

Setting objective functions to average capacity across packs without penalizing cell-to-cell variance within a single string.
Treating CO2 reduction as a binary choice without evaluating intermediate modal shift options.
Accepting non-compliant shipments without safety remediations, exposing personnel to hazards.
Using static linear historical demand extrapolation for dynamic EV retirement rates.

Test Yourself: Rebaba Interview Questions

Three questions from the Rebaba bank.

Type · network-design

Rebaba needs to expand its collection network for end-of-life battery packs across Northern and Central Europe. How would you evaluate whether to establish regional consolidation hubs or ship directly from fleet depots to a single mega-refurbishment plant?

Type · quality-control

A major automotive partner sends a batch of 500 battery modules where 30% fail incoming State of Charge and impedance screening due to severe degradation. How do you re-route these sub-spec inputs without halting downstream Energy Storage System cabinet assembly?

Type · linear-programming

How would you set up an optimization model to match incoming second-life battery modules with varied internal resistance and capacity limits into matched strings for grid-scale Energy Storage Systems?

9 of 15 questions shown

Recruiter Screen

1
Type · motivation
Why are you interested in circular supply chains for second-life EV batteries at Rebaba, and how does your background prepare you for supply chain friction specific to non-standardized feedstocks and hazardous waste regulations?

Operations Case

2
Type · reverse-logistics
We source used battery modules from automotive OEMs across Europe, but incoming shipments arrive with highly variable State of Health (SoH) and safety conditions. How would you design a triage and testing bottleneck mitigation plan at our central refurbishment facility?
3
Type · network-design
Rebaba needs to expand its collection network for end-of-life battery packs across Northern and Central Europe. How would you evaluate whether to establish regional consolidation hubs or ship directly from fleet depots to a single mega-refurbishment plant?

Forecasting & Planning

4
Type · demand-planning
Unlike traditional manufacturing, our feedstock supply depends on EV retirement curves and OEM warranty returns. How do you build a demand and supply balancing framework when feedstock availability fluctuates by ±35% quarter-over-quarter?
5
Type · sop-process
Walk me through how you would run an S&OP alignment meeting when the commercial team secures a contract for a 20MWh stationary storage project, but supply forecasting indicates a 30% shortfall in high-grade second-life modules over the target quarter.
+ 1 more questions in this round (sign up to unlock)

Optimization

6
Type · route-optimization
Transporting damaged or end-of-life lithium batteries requires ADR Class 9 hazardous waste compliance and specialized transport containers. How do you optimize European logistics routes to minimize transport costs while adhering to legal transit time limits and container rotation limitations?
7
Type · linear-programming
How would you set up an optimization model to match incoming second-life battery modules with varied internal resistance and capacity limits into matched strings for grid-scale Energy Storage Systems?
+ 3 more questions in this round (sign up to unlock)

Behavioral / Leadership

8
Type · supplier-negotiation
Describe a situation where an automotive partner failed to meet agreed dangerous goods packaging standards for incoming battery shipments, risking line stops. How did you resolve the compliance issue while protecting the commercial partnership?
9
Type · cross-functional-alignment
STAR
Walk me through a time you pushed back against a proposed engineering modification to a battery enclosure design because of severe lead time and supplier tooling risks it introduced.
