The Farfetch DNA (TL;DR)
The Farfetch Interview Loop
Your onsite loop will typically consist of 5 rounds.
- 1
Round 1
Recruiter ScreenMotivation, role fit, logistics. - 2
Round 2
Coding ScreenLeetCode-medium algorithmic problems under time pressure. - 3
Round 3
System DesignDistributed systems, trade-offs at scale, architecture under constraints. - 4
Round 4
Onsite CodingLeetCode-hard, debugging, code clarity, edge cases. - 5
Round 5
Behavioral / LeadershipPast evidence of ownership, influence, resolving conflict.
The Danger Zone: Top Reasons Candidates Fail
Based on our database of Farfetch interview outcomes, avoid these common traps:
- Focusing on superficial errors (e.g., typos) without tracing the data flow or logic.
- Using a simplistic approach like just counting occurrences of products within categories without considering category hierarchy or co-occurrence.
- Brute-force approach that iterates through all records for each query, ignoring the time window or customer ID.
- Underestimating the scale and concurrency challenges of real-time updates for a global marketplace.

Type · algorithm
Given a list of product IDs and their corresponding stock levels, and a list of customer orders with product IDs, write a function to determine which orders can be fulfilled. Assume each order requires one unit of each product listed in it. Optimize for efficiency. - 3
Type · algorithm
You are given a dataset of customer browsing history, where each entry contains a customer ID, a product ID, and a timestamp. Design an algorithm to find the top K most frequently viewed products by a specific customer within a given time window. - + 1 more questions in this round (sign up to unlock)
