How to Pass the DAZN Software Engineer Interview in 2026

The DAZN DNA (TL;DR)

DAZN's interview loop heavily weights a candidate's ability to navigate the complexities of live sports streaming, particularly how they'd enhance the DAZN app's real-time user experience. Interviewers look for examples of scaling high-traffic, low-latency systems and strategic thinking around global content rights.

The DAZN Interview Loop

Your onsite loop will typically consist of 5 rounds.

1
Round 1
Recruiter Screen
Motivation, role fit, logistics.
2
Round 2
Coding Screen
LeetCode-medium algorithmic problems under time pressure.
3
Round 3
System Design
Distributed systems, trade-offs at scale, architecture under constraints.
4
Round 4
Onsite Coding
LeetCode-hard, debugging, code clarity, edge cases.
5
Round 5
Behavioral / Leadership
Past evidence of ownership, influence, resolving conflict.

The Danger Zone: Top Reasons Candidates Fail

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

Not considering fault tolerance and redundancy for critical components.
Not reflecting on the effectiveness of their learning strategy.
Ignoring the 'recently watched' aspect and just recommending based on overall history.
Using a simple count without considering the time window, leading to incorrect throttling.

Test Yourself: Real DAZN Questions

Three real prompts pulled from our database.

Type · Ownership

We often deal with complex regional content rights that restrict availability. Describe a time when you identified a systemic bottleneck in our entitlement or geo-fencing service that was causing friction for users. How did you drive the resolution of this issue from identification to production deployment?

Type · String Manipulation

DAZN displays personalized content recommendations. Given a user's viewing history (a list of video IDs) and a catalog of available videos (with metadata like genre, duration, etc.), write a function to generate a ranked list of recommended video IDs. The ranking should prioritize videos of the same genre as recently watched content, then by popularity.

Type · Algorithm

Given a list of live sports events with their start and end times, write a function to find the maximum number of concurrent events happening at any point in time. Assume times are integers representing minutes.

9 of 13 questions shown

Recruiter Screen

1
Type · Motivation
What interests you about working at DAZN, and how do you see your skills contributing to our mission of making sports more accessible and engaging?

Coding Screen

2
Type · Algorithm
Given a list of live sports events with their start and end times, write a function to find the maximum number of concurrent events happening at any point in time. Assume times are integers representing minutes.
3
Type · Data Structures
Implement a rate limiter for API requests. You are given a stream of request timestamps and a limit (e.g., 100 requests per minute). Design a data structure and algorithm to allow or deny requests based on this limit.

System Design

4
Type · API Design
Design the backend system for DAZN's live sports streaming service. Consider aspects like user authentication, video ingestion, content delivery network (CDN) integration, and handling peak loads during major events.
5
Type · Database Design
Design a database schema to store user viewing history, preferences, and subscription data for DAZN. Consider how to efficiently query this data for personalization and analytics.

Onsite Coding

6
Type · Algorithm
Implement a function to detect if a live stream has buffering issues. Given a sequence of timestamps representing when video chunks are requested and received by the client, and the expected duration of each chunk, determine if the playback would likely stall. Assume a fixed playback buffer size.
7
Type · Debugging
A user reports that sometimes, after watching a live event, their 'continue watching' list doesn't update correctly, showing old content or missing the recently finished event. Here's a simplified snippet of the code responsible for updating the user's watch history. Debug and fix the potential issues.

Behavioral / Leadership

8
Type · Conflict Resolution
During a high-stakes live event, we faced a critical trade-off between prioritizing low-latency video delivery and maintaining broadcast stability for a massive concurrent audience. Tell me about a time you navigated a technical impasse where two teams had conflicting priorities for system performance. How did you reconcile these competing engineering requirements?
9
Type · Ownership
We often deal with complex regional content rights that restrict availability. Describe a time when you identified a systemic bottleneck in our entitlement or geo-fencing service that was causing friction for users. How did you drive the resolution of this issue from identification to production deployment?
