How to Pass the InPost Supply Chain Interview in 2026

The InPost DNA (TL;DR)

InPost's focus on expanding its network of Automated Parcel Machines drives interviews to assess a candidate's ability to scale infrastructure efficiently. They seek individuals who can articulate how their contributions directly impact operational metrics and the company's "Performance Highlights".

The Danger Zone: Top Reasons Candidates Fail

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

Focusing only on the customer-facing aspect of lockers and not the operational flow.
Not establishing clear communication channels between demand planners and operations teams.
Not accounting for operational costs (e.g., collection routes, maintenance) in the location decision.
Proposing solutions that significantly increase costs without clear justification.

Test Yourself: Real InPost Questions

Three real prompts pulled from our database.

Type · Ownership

Describe a time when you identified an inefficiency in locker-to-depot transit times that was not part of your core KPIs. How did you investigate the root cause and implement a fix that improved the parcel flow?

Type · Conflict Resolution

Share a situation where you had to balance the competing priorities of a high-volume locker site requiring frequent collections and the need to optimize driver route density. How did you reconcile these operational trade-offs?

Type · Route Optimization

Describe how you would optimize the collection routes for InPost delivery drivers to minimize mileage and time while ensuring all lockers are serviced efficiently. What data would you need?
