Your onsite loop will typically consist of 4 rounds.

  1. 1

    Round 1

    Recruiter Screen
    Motivation, operations background, supply chain interest.
  2. 2

    Round 2

    Operations Case
    End-to-end supply chain optimization, bottleneck diagnosis, network design.
  3. 3

    Round 3

    Forecasting & Planning
    Demand planning, S&OP, inventory optimization, working with statistical and ML forecasts.
  4. 4

    Round 4

    Optimization
    Linear programming intuition, route optimization, facility location, trade-offs between cost/service/CO2.

The Danger Zone: Top Reasons Candidates Fail

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

  • Over-producing finished standard devices before receiving custom fit dimensions.
  • Focusing only on direct freight cost reduction while ignoring working capital increases from duplicating safety stock across regional hubs.
  • Giving generic answers about supply chain without referencing the specific complexities of customized ear-level devices.
  • Setting high minimum order quantities that result in years of excess holding costs.

Test Yourself: Sonova Interview Questions

Three questions from the Sonova bank.

Type · reverse_logistics

Medical devices require strict return-merchandise-authorization (RMA) tracking and serial-number verification for refurbishing or repair. How would you design a global reverse logistics network to reduce repair turn-around time?

Type · traceability_quality

A batch of micro-electronic receiver components fails post-assembly quality testing due to an unannounced material change by a Tier-2 supplier. How do you construct a supply chain protocol to isolate affected stock and mitigate line downtime?

Type · linear_programming

Formulate an optimization model logic to allocate micro-chip component inventories across global assembly centers subject to regional regulatory certifications, air cargo weight constraints, and maximum delivery lead times.
