How to Pass the AutoStore Software Engineer Interview in 2026

The AutoStore DNA (TL;DR)

AutoStore's technical assessment prioritizes a candidate's ability to optimize complex electromechanical systems, particularly within the constraints of their cube storage grid. They seek individuals who can articulate robust solutions for scalability and reliability, ensuring the seamless operation of their Red Line and Black Line robots.

  5. 5

    Round 5

    Behavioral / Leadership
    Past evidence of ownership, influence, resolving conflict.

The Danger Zone: Top Reasons Candidates Fail

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

  • Ignoring potential system-level failures (e.g., robot offline, communication loss).
  • Not handling the time delta correctly, leading to false positives or negatives.
  • Inefficient search for nearest robot (e.g., linear scan of all robots).
  • Choosing a centralized approach that could become a bottleneck.

Test Yourself: Real AutoStore Questions

Three real prompts pulled from our database.

Type · Design

Design a system for managing the charging schedules of thousands of robots in a large AutoStore warehouse. Consider factors like battery degradation, energy costs throughout the day, and ensuring robots are available when needed for order fulfillment.

Type · Debugging

A fellow engineer has written code to manage bin inventory. It seems to have a race condition where multiple robots might try to access or update the same bin simultaneously, leading to incorrect counts. Here's a snippet of the code [provide a code snippet]. Can you identify the potential race condition and suggest a fix?

Type · Algorithm

Implement a function that takes a 2D array representing the AutoStore grid and a list of bin locations. The function should return the optimal path for a single robot to visit all specified bins in the most efficient order, minimizing travel distance. Assume the robot can only move horizontally and vertically and starts at (0,0).

    Type · Motivation

    What interests you about AutoStore's unique approach to warehouse automation, and how do you see your software engineering skills contributing to our mission of revolutionizing storage and retrieval?

  1. 2

    Type · Algorithm

    Given a stream of incoming robot commands (e.g., 'move_to(x, y)', 'pick_item(bin_id)', 'place_item(location)'), design a data structure to efficiently track the current state and location of all robots in the warehouse grid. You need to support queries for the nearest available robot to a specific bin or pick-up location.
  2. 3

    Type · Algorithm

    Imagine a simplified AutoStore grid where robots can only move horizontally or vertically. Write a function to calculate the minimum number of moves a robot needs to get from its current position (x1, y1) to a target position (x2, y2), considering that some cells in the grid might be blocked by bins or other robots.

Assume the robot can only move horizontally and vertically and starts at (0,0).
  2. 7

    Type · Algorithm

    You are given a log of robot movements, including timestamps and grid coordinates. Write a function to detect and report any instances where two robots occupy the same grid cell simultaneously or within a very small time delta (e.g., 1 second), indicating a potential collision or near-miss.

    Type · Ownership

    Tell me about a time you encountered a significant technical challenge or bug in a production system that was impacting users. What steps did you take to diagnose, resolve, and prevent recurrence?
  2. 9

    Type · Collaboration

    Our Red Line robots require extremely low latency for pathfinding updates. Describe a time you had to defend a specific architectural trade-off regarding memory footprint or processing overhead against a team member who prioritized a different optimization strategy for our grid controller.
