  2. 2

    Round 2

    Coding Screen
    LeetCode-medium algorithmic problems under time pressure.
  3. 3

    Round 3

    System Design
    Distributed systems, trade-offs at scale, architecture under constraints.
  4. 4

    Round 4

    Onsite Coding
    LeetCode-hard, debugging, code clarity, edge cases.
  5. 5

    Round 5

    Behavioral / Leadership

The Danger Zone: Top Reasons Candidates Fail

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

  • Overlooking the importance of auditability and compliance logging
  • Inefficient database queries or lack of indexing for favorite-related operations.
  • Focusing on personal victory rather than business trade-offs
  • Missing edge cases, such as division by zero or handling of empty historical data.

Test Yourself: Real Entain Questions

Three real prompts pulled from our database.

Type · learning

Entain operates under strict regulatory requirements that change frequently across different global jurisdictions. Tell me about a time you had to adapt your software design to accommodate a sudden shift in regional compliance or data privacy laws. What was your process for integrating these new constraints into an existing high-traffic service?

Type · debugging

We have a service that calculates the probability of a specific outcome in a game based on historical data and live events. A customer reports that for a particular match, the calculated probability seems consistently wrong, always showing 0% for a specific outcome that is still possible. Here's a simplified snippet of the calculation logic. Identify potential bugs and suggest fixes.

Type · system-design

We need to build a robust notification system that can send personalized alerts to millions of users across multiple channels (push, SMS, email) for various events like 'game starting soon', 'bet won/lost', or 'new content available'. Design this system, considering reliability, scalability, and delivery guarantees.

9 of 13 questions shown

1

Recruiter Screen

1
  1. 1

    Type · motivation

    Entain operates in the highly dynamic media and entertainment space, with a focus on sports betting and gaming. What specifically about our business model and the challenges within this industry excites you as a Software Engineer?
2

Coding Screen

3
  1. 2

    Type · algorithmic

    Imagine you're building a real-time sports betting odds display. Given a stream of incoming odds updates (e.g., `{'match_id': 123, 'team_a_odds': 2.1, 'team_b_odds': 1.8}`), design a data structure and algorithm to efficiently store and retrieve the latest odds for any given `match_id`. You should also be able to handle a high volume of updates.
  2. 3

    Type · algorithmic

    A user is browsing through live sports events on our platform. We want to recommend related events they might be interested in. Given a list of `(user_id, event_id)` pairs representing events a user has viewed, and a list of `(event_id_1, event_id_2)` pairs representing events that are considered 'related' (e.g., same sport, same league), write a function to find all events related to any event a specific user has viewed. Assume events can be related transitively (if A is related to B, and B to C, then A is related to C).

System Design

3
  1. 4

    Type · system-design

    Design a system to track and display live betting trends for popular events. This system should ingest millions of bets per hour, aggregate them in near real-time to show metrics like 'percentage of bets on Team A', 'average stake', and 'most popular outcome', and serve these trends to our frontend applications with low latency.
  2. 5

    Type · system-design

    Entain's media platforms often feature personalized content recommendations. Design a recommendation engine that can suggest relevant articles, videos, or betting markets to users based on their past interactions (views, clicks, bets) and the behavior of similar users. Consider aspects like data collection, model training, and serving.

Onsite Coding

3
  1. 6

    Type · algorithmic

    Implement a function that takes a list of user sessions, where each session is a list of timestamps representing user activity. The function should group sessions into 'active periods' where activity within a session is no more than 30 minutes apart. Return a list of tuples, where each tuple represents an active period and contains the start time and end time of that period across all sessions.
  2. 7

    Type · debugging

    We have a feature that allows users to 'favorite' certain matches or events. The backend service responsible for managing these favorites is experiencing intermittent failures, sometimes returning incorrect favorite counts or failing to add/remove favorites. Here's a simplified code snippet for the favorite management API endpoint. Debug and improve this code.

Behavioral / Leadership

3
  1. 8

    Type · ownership

    Tell me about a time you encountered a significant technical debt or performance bottleneck in a system you were responsible for. What steps did you take to address it, and what was the outcome?
  2. 9

    Type · collaboration

    In our sports trading platforms, we often face a trade-off between prioritizing low-latency data updates for live betting and ensuring 100 percent consistency for financial transactions. Describe a time you advocated for a specific architectural trade-off that clashed with the priorities of another engineering or product team. How did you align the teams to reach a consensus while maintaining system integrity?
