As a DevOps Engineer at SAP, you are stepping into a role that powers the digital transformation of global enterprises. SAP is not just about legacy ERP systems; it is aggressively pivoting toward the cloud with the Business Technology Platform (BTP) and cloud-native solutions. In this position, you act as the bridge between development and operations, ensuring that the software powering 87% of total global commerce is delivered reliably, securely, and efficiently.

You will be responsible for automating the software delivery lifecycle, managing complex cloud infrastructure, and ensuring system stability at a massive scale. Whether you are working on SAP S/4HANA Cloud, SuccessFactors, or the underlying BTP infrastructure, your work directly impacts the speed at which SAP delivers innovation to customers. You will work in a hybrid, multi-cloud environment (AWS, Azure, GCP, and SAP’s own data centers), tackling challenges related to scalability, high availability, and automated recovery.

This role offers a unique mix of stability and cutting-edge technical challenge. You are not just maintaining servers; you are engineering the platforms that allow thousands of developers to deploy code seamlessly. Expect to work in international teams where cross-cultural collaboration is the norm, and where your ability to solve complex infrastructure problems is just as valued as your coding skills.

The following questions are representative of what you might face. They are drawn from actual candidate experiences and are designed to test the depth of your knowledge. Remember, interviewers at SAP often drill down—if you answer "I use Git," they will ask "How does Git handle hash collisions?"

Technical: Linux & Networking

• "What is the difference between a process and a thread in Linux?"
• "Explain the boot process of a Linux system from power-on to user login."
• "How would you check which process is consuming the most memory on a server without using top?"

Preparation for SAP requires a shift in mindset. You are not just being tested on your ability to write a script; you are being evaluated on your ability to maintain integrity in a complex, mission-critical environment.

Key Evaluation Criteria:

Technical Integrity & Resume Accuracy – This is the most critical filter at SAP. Interviewers will rigorously cross-reference your answers with your CV. If you list a technology, you must be able to discuss it in depth. Surface-level knowledge of tools you claim to be an expert in is a red flag.

Core Infrastructure Knowledge – SAP values foundational knowledge over trend-chasing. You must demonstrate a deep understanding of Linux internals, networking fundamentals, and container orchestration. They evaluate whether you understand how the tools work under the hood, not just how to use them.

Operational Problem Solving – You will be judged on your approach to troubleshooting. How do you handle a production outage? How do you debug a failing pipeline? Interviewers look for a structured, logical approach to isolating issues in distributed systems.

Global Collaboration – Because SAP teams are distributed globally (e.g., Germany, India, Israel, Brazil, USA), you must demonstrate the ability to communicate technical concepts clearly in English and work effectively across time zones and cultures.

The interview process for a DevOps Engineer at SAP is thorough and can vary significantly depending on the specific product team and location. Generally, the process is designed to test both your theoretical knowledge and your practical application of skills. You should expect a multi-stage process that prioritizes technical depth.

Typically, the journey begins with an HR screening to assess cultural fit and language proficiency. This is followed by a technical screening, often with a team member, which may feel like a rapid-fire test of your resume claims. If successful, you will move to deeper technical rounds, which may include a panel interview or a "take-home" assignment involving a practical DevOps task (e.g., setting up a pipeline or containerizing an application). The final stages usually involve behavioral interviews with team or group leads to assess your soft skills and alignment with SAP’s values.

Be aware that the process pace can be inconsistent. Some candidates experience a swift process, while others report gaps in communication or delays between rounds. It is crucial to remain patient and proactive. The technical interviews are known for being "drills"—interviewers will pick specific technologies and ask increasingly difficult questions until they find the limits of your knowledge.

This timeline illustrates the typical flow from application to offer. Use this to plan your energy; the middle stages (Technical Deep Dive and Assignment) are the most intensive and require the heaviest preparation. Note that the "Assignment" phase is not universal—some teams prefer live coding or whiteboard architecture sessions instead.

SAP interviews are strictly competency-based. Based on candidate reports, you should focus your preparation on the following areas.

Resume Verification & Technical Breadth

This is a distinct characteristic of SAP interviews. Interviewers often use your resume as the primary agenda.

• Why it matters: SAP values transparency. Claiming skills you do not possess is seen as a integrity issue.
• Evaluation: Panelists may go line-by-line through your skills section.
• Strong performance: You can explain the architecture, common issues, and specific use cases for every tool listed on your CV.

Be ready to go over:

• Project specifics: Explaining exactly what your role was in a migration or implementation.
• Tool justification: Why you chose Jenkins over GitLab CI, or Terraform over CloudFormation.
• Depths of knowledge: Expect questions on "unnecessary details" regarding versioning, flags, or configuration files.

Containerization & Orchestration (Docker & Kubernetes)

Given SAP's cloud-native focus, this is a non-negotiable skill set.

• Why it matters: Most modern SAP applications run on Kubernetes clusters.
• Evaluation: You will be asked to debug pod failures, explain networking, and discuss storage.
• Strong performance: Moving beyond "kubectl run" to explaining the Kube-scheduler, etcd, ingress controllers, and service meshes.

Be ready to go over:

• Docker internals: Layers, multi-stage builds, and optimizing image size.
• Kubernetes architecture: Control plane vs. worker nodes, sidecar patterns.
• Helm charts: Creating and managing deployments.
• Advanced concepts: Custom Resource Definitions (CRDs), Operator pattern, and network policies.

Example questions or scenarios:

• "Explain the lifecycle of a pod from creation to termination."
• "How would you troubleshoot a CrashLoopBackOff error in a production cluster?"
• "Differentiate between a StatefulSet and a Deployment."

CI/CD & Automation

• Why it matters: You are hired to improve developer velocity and system reliability.
• Evaluation: Assessing your ability to design robust pipelines that catch errors early.
• Strong performance: Demonstrating knowledge of Groovy scripting (for Jenkins), YAML workflows, and integration with testing frameworks.

Be ready to go over:

• Pipeline as Code: Jenkinsfiles, GitLab CI YML.
• Version Control: Git branching strategies (GitFlow vs. Trunk-based) and resolving merge conflicts.
• Infrastructure as Code: Terraform state management, modules, and Ansible playbooks.

Linux & Operating Systems

• Why it matters: The cloud runs on Linux. You need to know what happens when the abstraction layers leak or fail.
• Evaluation: Questions on kernel, memory management, and shell scripting.
• Strong performance: Ability to write bash/python scripts on the fly and debug system performance issues using CLI tools.

Be ready to go over:

• System calls: Understanding permissions, file systems, and processes.
• Networking: TCP/IP handshake, DNS resolution, load balancing.
• Scripting: Automating daily tasks using Python or Bash.

As a DevOps Engineer at SAP, your day-to-day work revolves around enabling the "Run Simple" philosophy through complex engineering. You will be responsible for designing, building, and maintaining the CI/CD pipelines that deliver SAP software to the cloud. This involves not just writing code, but actively monitoring the health of production environments using tools like Splunk, Dynatrace, or Prometheus.

You will collaborate closely with development teams to evangelize DevOps culture. This means you aren't just a ticket-taker; you are a consultant to internal teams, helping them containerize their applications and migrate legacy monoliths to microservices architectures. You will frequently work with SAP BTP (Business Technology Platform), integrating open-source tools with SAP's proprietary ecosystem.

Expect to spend a significant portion of your time on Infrastructure as Code (IaC). You will provision resources on hyperscalers (AWS, Azure, GCP) using Terraform or Ansible, ensuring that environments are reproducible and secure. Operational stability is paramount, so you will also be part of on-call rotations, troubleshooting incidents in real-time and conducting post-mortems to prevent recurrence.
