Fanduel DevOps Engineer interview questions & guide 2026

Preparation for this role should be structured around demonstrating both depth of technical knowledge and breadth of operational experience. Do not just list the tools you have used; explain the architectural patterns you have implemented and why those choices were successful.

Role-related knowledge – You must demonstrate a firm grasp of cloud architecture, Linux internals, and modern automation tools. Interviewers will look for your ability to explain the "how" and "why" behind your technical stack rather than just syntax.

Problem-solving ability – We evaluate how you break down ambiguous, complex systems problems. Be prepared to talk through your methodology—starting with observability and data collection before jumping to conclusions.

Communication & Collaboration – DevOps at Fanduel is a team sport. We assess your ability to communicate technical trade-offs to non-technical stakeholders and your willingness to mentor others during incident response.

The Fanduel interview process is designed to be thorough, ensuring that candidates possess both the technical rigor and the collaborative spirit required for our fast-paced environment. Typically, the process begins with a recruiter screen to assess interest and high-level alignment, followed by a series of technical deep-dives. You should expect a mix of remote calls and potential in-person sessions, depending on your location.

The process is generally iterative. While technical assessments are a staple, they are intended to mirror real-world tasks. We focus on your approach to debugging and architectural design, valuing your thought process as much as the final technical solution.

The timeline above represents a standard progression, moving from initial screening through to technical vetting and team fit. Use this to pace your study schedule, ensuring you have time to refresh on core concepts like Terraform, Linux networking, and system design before your technical rounds.

Cloud & Infrastructure as Code

We need to know that you can manage environments that evolve rapidly. Proficiency in Terraform and cloud-native services is essential.

Be ready to go over:

• State management – Handling state files in collaborative environments.
• Modularization – Building reusable infrastructure components.
• Security – Implementing least-privilege access and secret management.

Example scenarios:

• "How do you handle drift detection in your Terraform environments?"
• "Describe your approach to rolling out infrastructure updates without downtime."

Observability & Debugging

The ability to identify and resolve issues in production is the hallmark of a senior DevOps Engineer.

Be ready to go over:

• Logging stacks – How to aggregate and query logs effectively.
• Metrics & Alerting – Defining SLOs and setting up meaningful alerts.
• Root Cause Analysis (RCA) – Your systematic approach to post-mortems.

Example scenarios:

• "You receive an alert for high CPU usage; what is your first step?"
• "How do you differentiate between a network issue and an application-level bottleneck?"

As a DevOps Engineer, your primary objective is to eliminate friction in the software development lifecycle. You will spend your day-to-day building and maintaining CI/CD pipelines, ensuring that our deployment processes are safe, repeatable, and fast. You will work closely with developers to understand their constraints, providing them with the platform tools they need to ship high-quality code.

Additionally, you will participate in the design of scalable infrastructure, ensuring that our systems can handle the massive traffic fluctuations inherent in the sports gaming industry. This involves not only writing automation scripts but also contributing to the architectural roadmap. You will be a key player in incident management, ensuring that when things do go wrong, we have the observability and automation in place to recover quickly.

A competitive candidate for this position will show a mix of hands-on technical skill and a strong grasp of site reliability principles.

• Must-have skills:
  • Proficiency in Linux system administration and networking.
  • Deep experience with Terraform or similar IaC tools.
  • Strong scripting capability (e.g., Python, Bash, or Go).
  • Experience with CI/CD tooling (e.g., Jenkins, GitLab CI, GitHub Actions).
• Nice-to-have skills:
  • Experience with Kubernetes and container orchestration at scale.
  • Familiarity with cloud providers like AWS or GCP.
  • Knowledge of observability tools like Prometheus, Grafana, or Datadog.
