Sun Life DevOps Engineer interview questions & guide 2026

Expect a mix of resume-specific deep dives and broad conceptual questions. The goal is to verify that you have actually performed the work listed on your profile and that you can think critically under pressure.

Technical & Tooling Questions

These questions test your command of the specific stack used by the Sun Life DevOps team.

• "What is the difference between a Terraform module and a resource?"
• "How do you handle configuration drift in an environment managed by Ansible?"

Preparation for the DevOps Engineer role at Sun Life requires a dual focus on deep technical proficiency and a clear understanding of the software development lifecycle (SDLC). Interviewers are looking for candidates who do not just know how to use tools, but who understand the "why" behind their implementation. You should be prepared to discuss your past projects with a high level of granularity, explaining the trade-offs you made and the business value you delivered.

Role-related knowledge – This is the core of the evaluation. Interviewers will test your hands-on experience with specific automation tools like Terraform and Ansible. You must demonstrate that you can write clean, maintainable code and manage infrastructure at scale while adhering to security best practices.

Problem-solving ability – You will be evaluated on how you approach systemic issues. Whether it is a bottleneck in a deployment pipeline or a production outage, the team wants to see a structured, logical approach to troubleshooting. You should be able to articulate how you identify root causes and implement long-term fixes rather than temporary patches.

Communication and Collaboration – DevOps at Sun Life is a team sport. You must be able to explain complex technical concepts to non-technical stakeholders and work effectively across different engineering pods. Strength in this area is shown through your ability to navigate ambiguity and influence others toward adopting better operational habits.

Culture Fit and Values – Sun Life values integrity, client-centricity, and a proactive mindset. Interviewers look for candidates who are lifelong learners and who take ownership of their work. Being able to discuss your professional goals and how they align with the company’s mission is essential for a positive evaluation.

The interview process for a DevOps Engineer at Sun Life is designed to be thorough yet conversational. It typically begins with an HR screening call to discuss your background, followed by a more intensive virtual interview with the technical team and hiring manager. While the atmosphere is often described as pleasant and professional, do not mistake the friendly tone for a lack of rigor. The team will dive deep into your technical choices and your understanding of modern DevOps principles.

You can expect the process to move at a steady pace initially, but be aware that final decisions can sometimes take longer as the hiring team reviews a diverse pool of candidates. Sun Life places a high premium on finding the right long-term fit, meaning they may prioritize "hands-on" experience in specific niche areas over general knowledge. Consistency in your technical explanations across different rounds is key to building trust with the interviewers.

The timeline above illustrates the standard progression from the initial application to the final offer. Candidates should use this to pace their preparation, focusing heavily on resume-based technical deep dives before the virtual team interview. Note that while the HR screen is high-level, the subsequent team interview is where the majority of technical vetting occurs.

Infrastructure as Code (IaC) and Automation

This is arguably the most critical area of evaluation. At Sun Life, the move toward automated environments means you must be an expert in defining and managing infrastructure through code. Interviewers will look for your ability to create repeatable, version-controlled environments that reduce manual intervention.

Be ready to go over:

• Terraform – Understanding providers, state management, modules, and how to structure Terraform code for enterprise environments.
• Ansible – Configuration management strategies, writing playbooks, and managing complex inventory across hybrid cloud setups.
• Idempotency – Explaining why it is important in automation and how you ensure your scripts can run multiple times without unintended side effects.

Example questions or scenarios:

• "How do you manage Terraform state files in a team environment to prevent conflicts?"
• "Describe a time you used Ansible to automate a complex multi-tier application deployment."
• "What are the advantages of using Terraform over manual cloud console configurations in a regulated industry like insurance?"

SDLC and CI/CD Pipelines

Sun Life focuses heavily on how code moves from a developer's machine to production. You need to demonstrate a holistic understanding of the Software Development Lifecycle (SDLC) and how DevOps practices accelerate this flow while maintaining quality.

Be ready to go over:

• Pipeline Design – How to build robust CI/CD pipelines using tools like Jenkins, GitLab CI, or GitHub Actions.
• Testing Integration – Where to shift-left security and automated testing within the pipeline.
• Branching Strategies – The pros and cons of GitFlow vs. Trunk-based development in a large organization.

Example questions or scenarios:

• "Walk us through a deployment pipeline you designed. What were the stages and why?"
• "How do you handle secrets management within your CI/CD workflows?"
• "What metrics do you track to measure the success of a DevOps implementation?"

General Programming and Scripting

While you may not be building consumer-facing apps, you are expected to have a solid foundation in programming. This allows you to build custom tooling and understand the challenges faced by the developers you support.

Be ready to go over:

• Scripting Languages – Proficiency in Python, Bash, or Go for automation tasks.
• API Integration – How to interact with cloud APIs or third-party tool APIs to extend functionality.
• Code Review – Your approach to reviewing infrastructure code and providing feedback to peers.

Advanced concepts (less common):

• Container orchestration with Kubernetes (K8s).
• Serverless architecture patterns.
• Service mesh implementations (e.g., Istio).

As a DevOps Engineer, your primary responsibility is to design, implement, and maintain the automation frameworks that power Sun Life’s digital ecosystem. You will spend a significant portion of your day writing Terraform plans and Ansible playbooks to provision and configure cloud resources. This is not a "siloed" role; you will work closely with software developers to ensure their applications are architected for cloud-native environments and that their deployment needs are met through self-service automation.

Beyond active development, you are responsible for the "health" of the platform. This includes monitoring system performance, optimizing cloud spend, and ensuring that all infrastructure meets Sun Life’s rigorous security and compliance standards. You will likely participate in architectural reviews, providing an operational perspective on new projects to ensure they are maintainable and scalable from day one.

You will also act as a mentor and advocate for DevOps culture. This involves documenting best practices, conducting workshops for development teams, and staying ahead of industry trends to suggest tool or process improvements. Your goal is to reduce friction in the development process, allowing Sun Life to respond more quickly to market changes and client needs.

Successful candidates for the DevOps Engineer position at Sun Life typically possess a blend of traditional systems administration knowledge and modern software engineering skills. The team looks for individuals who have "battle-tested" experience in production environments.

• Technical Skills – Mastery of Terraform and Ansible is often non-negotiable. You should also be comfortable with cloud platforms (AWS or Azure), containerization (Docker), and standard CI/CD tooling.
• Experience Level – Typically, 3–5 years of experience in a DevOps or Site Reliability Engineering (SRE) role is required for mid-level positions, while senior roles may require 7+ years with a track record of leading large-scale migrations.
• Soft Skills – Strong verbal and written communication skills are essential. You must be able to explain technical debt and the value of automation to stakeholders who may prioritize feature delivery over operational stability.
