The RELX 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 RELX interview outcomes, avoid these common traps:
- Off-by-one errors in loop or range calculations.

Test Yourself: Real RELX Questions
Three real prompts pulled from our database.
Type · algorithmic
Given a list of articles, each with a unique ID and a list of tags, write a function to find all articles that share at least K tags with a given target article. Optimize for scenarios where the number of articles and tags per article can be very large.
Type · architecture
Imagine RELX wants to launch a new feature that personalizes the news feed for each user based on their interests and past interactions. Design the backend services required to support this, including how user profiles are managed, how content is scored and ranked, and how the feed is delivered with low latency.

Coding Screen
3- 2
Type · algorithmic
Given a list of articles, each with a publication date and a list of keywords, write a function to find the top K most relevant articles for a given search query. Relevance is determined by the number of shared keywords and the recency of the article. - 3
Type · algorithmic
You are given a stream of user activity logs, where each log entry contains a user ID and the content ID they interacted with. Design a system to detect if any user has viewed more than N distinct content items within a M-minute sliding window. Return the user IDs violating this condition. - + 1 more questions in this round (sign up to unlock)

System Design
3- 4
Type · architecture
Design a system to recommend related articles to users based on their reading history and the content of the articles they've viewed. Consider scalability for millions of users and a large article corpus. - 5
Type · architecture
Design a content ingestion pipeline for a media platform. This pipeline needs to handle various content formats (text, images, videos), extract metadata, perform basic content analysis (e.g., keyword extraction), and store it efficiently for search and retrieval. Discuss potential bottlenecks and how to mitigate them. - + 1 more questions in this round (sign up to unlock)

Onsite Coding
4- 6
Type · algorithmic
Implement a function that takes a large text document and returns the N most frequent words, ignoring common stop words (like 'the', 'a', 'is'). The function should be efficient for documents potentially gigabytes in size. - 7
Type · algorithmic
Given a list of articles, each with a unique ID and a list of tags, write a function to find all articles that share at least K tags with a given target article.
