How long does the Ocado Group interview process take?

Most candidates spend between 4 and 8 weeks from recruiter screen to offer. The onsite loop itself runs in a single day or is split across two half-days, with debrief and offer typically within 5 business days after.

How should I prepare specifically for Ocado Group?

Focus on three things: (1) the company DNA shown above - what they actually grade for, (2) the rounds in your loop, especially the round most candidates underestimate, and (3) drilling on the question types in this guide using a structured framework like CIRCLES or STAR.

Does this apply to engineering or design roles at Ocado Group?

The DNA stays the same - what changes is the round mix. SWE candidates face coding screens instead of Product Sense; designers face portfolio reviews and design exercises. The "what they value" and behavioral signals carry across all functions.

The Danger Zone: Top Reasons Candidates Fail

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

Failing to consider strategies for handling concurrent updates and preventing overselling.
Designing a static routing system that doesn't adapt to real-time changes.
Giving a generic answer that could apply to any tech company.
Not reflecting on the lessons learned or how they applied them later.

Coding Screen

2
Type · algorithmic
Given a list of customer orders, each with a list of items and a delivery slot, write a function to determine if a specific delivery van can fulfill all orders within its capacity and time window. Consider item weights, van volume, and time constraints for each stop.
3
Type · algorithmic
Imagine Ocado's warehouse picking system. You are given a 2D grid representing the warehouse floor and a list of item coordinates that need to be picked for an order. Write a function to calculate the minimum path length for a robot to pick all items in the given order, starting from a charging station.

Onsite Coding

6
Type · algorithmic
Ocado's automated warehouses use a system to manage the flow of items. Given a sequence of operations (e.g., 'add item X to bin Y', 'move item X from bin Y to bin Z', 'retrieve item X from bin Y'), implement a data structure that can efficiently perform these operations and also answer queries like 'how many items are currently in bin Y?' or 'which bin is item X currently in?'. Assume items and bins are uniquely identified.
7
Type · debugging
A critical service responsible for processing customer payments is intermittently failing, causing some orders to be stuck in a 'pending payment' state. The error logs are sparse. Describe your process for diagnosing and fixing this issue, including potential code changes or infrastructure adjustments.
