Problem Statement: Truck Load & Route Optimization
Truck load optimization design note #1 (understanding): Freight brokers need to fill trailers, respect axle and cube limits, and sequence multi-stop LTL pickups before linehaul. Interviewers test whether you treat this as capacitated VRP with weight AND volume dimensions—not passenger ride matching.
| Concern | Design choice |
|---|---|
| Match | Match shipments to trucks under dual capacity (lbs + cubic ft) |
| Sequence | Sequence stops with dock appointments and HOS driver limits |
| Minimize | Minimize empty miles and detention while honoring delivery windows |
| Publish | Publish immutable load plans brokers and drivers can execute |
Metrics & operations
Track load_utilization_pct, empty_miles_ratio, plan_solve_p99_sec, unassigned_lbs_per_day.
Edge case
Oversized freight must route to equipment class; never silently squeeze onto 53ft dry van.
Runbook snippet
When challenged on section 1, quantify tenders and stops before naming cloud SKUs. Page on-call if unassigned_rate exceeds 5% after morning batch.
1 public record Shipment(String id, double weightLbs, double volumeCuFt, TimeWindow dockWindow) {}
1 def utilization(w, cap_w, v, cap_v): 2 return max(w/cap_w, v/cap_v)
1 export interface TruckSpec { trailerType: string; maxLbs: number; maxCuFt: number; }
Why interviewers care
Truck Load Optimization interviews reward crisp scope, explicit trade-offs, and failure stories—not generic microservice diagrams.
