1. What is an AI Engineer at SAP?

As an AI Engineer at SAP, you are stepping into a role that sits at the intersection of enterprise scale and cutting-edge intelligence. SAP is not just a software provider; it is the operational backbone for the majority of the world’s transaction revenue. Consequently, the AI Engineering function here is focused on "Business AI"—building reliable, relevant, and responsible AI systems that empower companies to run their operations more efficiently.

In this position, you will move beyond theoretical modeling to practical implementation. You will work on integrating Generative AI, Machine Learning, and Deep Learning capabilities directly into SAP’s vast ecosystem, such as the Business Technology Platform (BTP) or flagship products like S/4HANA. The impact of your work is massive; a small optimization in an AI model here can streamline supply chains, improve financial forecasting, or automate HR processes for thousands of global customers.

This role requires a blend of research curiosity and engineering rigor. You are not just training models in isolation; you are building scalable, production-grade AI services that must adhere to strict security, privacy, and ethical standards. Whether you are working on the Joule copilot or specialized industry solutions, you will be part of a team driving the next evolution of enterprise software.

2. Getting Ready for Your Interviews

Preparing for an interview at SAP requires a shift in mindset. You need to demonstrate that you are a "T-shaped" engineer: deep in AI/ML methodologies but broad enough to understand software engineering principles and business context.

Your interviewers will evaluate you against these core criteria:

Technical Versatility SAP teams vary significantly in their tech stacks. You must demonstrate strong foundations in core Data Structures and Algorithms (DSA) while also showing deep expertise in AI/ML frameworks. The ability to switch between discussing model architecture and writing clean, efficient production code is essential.

Problem-Solving & Adaptability Interviewers want to see how you tackle ambiguity. You will be evaluated on your approach to new problems—specifically, how you break down complex requirements into solvable technical components. Since the AI field changes rapidly, showing how you "cope with the changing field" and keep your skills current is a specific evaluation point.

Engineering Maturity It is not enough to build a model; you must know how to serve it. Expect scrutiny on your comfort with backend engineering, API design, and deployment pipelines. You need to show that you understand the lifecycle of software, not just the lifecycle of a model.

Collaborative Communication SAP values consensus and collaboration. You will be assessed on your ability to explain complex technical concepts to non-experts and your willingness to work within a global, distributed team structure.

3. Interview Process Overview

The interview process for an AI Engineer at SAP is comprehensive and can be somewhat variable depending on the specific team (e.g., SAP AI Core vs. a specific product team like SuccessFactors). Generally, the process spans approximately 4 weeks and is designed to test both your fundamental coding skills and your domain-specific knowledge.

You should expect a multi-stage process that typically begins with a screening or a take-home assessment, followed by 2–3 rounds of technical interviews. A distinct feature of SAP’s process is the variability in technical focus; some candidates report a heavy emphasis on classic LeetCode-style algorithms with little AI focus, while others face deep-dives into AI/ML specific take-home tasks. You must be prepared for both extremes. The atmosphere is generally described as professional and strictly technical, though interactions with hiring managers will pivot toward your resume and past project experiences.

The final stages often involve a mix of technical validation and "personality" or behavioral questions to ensure cultural alignment. The interviewers are looking for consistency—can you code what you claim on your resume, and can you explain why you made those choices?

Interpreting the timeline: This visual outlines the standard flow from application to offer. Note that the "Technical Assessment" phase is the most variable; it may be a live coding session or a take-home project depending on the hiring manager's preference. Use the gaps between rounds to refresh your knowledge on the specific team's product focus, as this often hints at whether the interview will lean more toward backend engineering or pure data science.

4. Deep Dive into Evaluation Areas

Candidates are evaluated across several distinct pillars. Based on recent interview data, you should structure your preparation around these key areas.

Data Structures & Algorithms (DSA)

Surprisingly for an AI role, many candidates report that their interviews focused almost exclusively on classic computer science fundamentals. This is often the "gatekeeper" stage.
