- 1.
A custom ABAP report that ran in minutes now takes hours as data has grown. How do you find the problem and what are the usual fixes?
Why they ask it: Performance tuning is one of the most frequent SAP development tasks.
A strong answer: Measure first with the runtime analysis and SQL trace tools to see whether the time is in the database or in ABAP processing. Common causes: SELECT statements inside loops, SELECT without a proper WHERE clause or index support, nested loops over standard internal tables, and reading more fields than needed. Fixes: set-based selects with joins or FOR ALL ENTRIES used carefully with an empty check, sorted or hashed tables, and pushing logic into the database with CDS views or AMDP on HANA.
- 2.
What is code pushdown on HANA and how does it change the way you write ABAP?
Why they ask it: S/4HANA changed ABAP development significantly. This tests whether you have kept up.
A strong answer: Moving data-intensive calculations into the database instead of fetching rows into the application server. In practice that means CDS views for data models with associations and annotations, Open SQL with expressions and aggregations, and AMDP where procedural database logic is needed. The old habit of selecting everything and looping in ABAP becomes the anti-pattern.
- 3.
The business wants to change standard SAP behaviour. What are your options, and which do you avoid?
Why they ask it: Modifying SAP the wrong way creates upgrade pain for years.
A strong answer: Prefer configuration first, then released enhancement points such as BAdIs, user exits and enhancement spots, and in S/4HANA the key user extensibility and released APIs for clean core. Modifying standard code directly is the last resort because it complicates upgrades and support. A strong answer mentions checking with the functional consultant whether the requirement can be met by configuration.
- 4.
Explain the transport process and what can go wrong when moving changes to production.
Why they ask it: Transports are how every SAP change reaches production, and mistakes cause outages.
A strong answer: Changes are recorded in transport requests in development, released and imported into quality for testing, then into production. Problems come from missing dependent objects, transports imported out of order, overwriting another developer's changes to a shared object, and client-dependent configuration missed. Good practice: small transports, clear documentation and coordination on shared objects.
- 5.
How would you expose SAP data to an external web application?
Why they ask it: Integration is increasingly central to SAP roles.
A strong answer: Build an OData service, using the RESTful application programming model with CDS views and behaviour definitions on newer systems or the gateway service builder on older ones, secure it with proper authorisation checks, and consider whether an integration platform should sit in between. Mention alternatives like IDocs or RFC for system-to-system use.
- 6.
A job fails in production overnight with a short dump. Walk me through your investigation.
Why they ask it: A debugging scenario grounded in SAP tooling.
A strong answer: Read the dump analysis for the error type, program and line, check the job log, and look at what data it was processing. Reproduce in a quality system with similar data if possible, using the debugger. Common causes include unexpected data, missing authorisation, lock conflicts or a recent transport. Fix, test and transport, then add handling or validation so the same data does not crash it again.
- 7.
Tell me about a time a functional consultant's specification was unclear or wrong. What did you do?
Why they ask it: SAP developers work from functional specs, and the relationship with consultants matters.
A strong answer: Raise questions early rather than guessing, walk through the business scenario with the consultant, propose alternatives when the spec conflicts with how SAP works, and document the agreed changes. Show respect for their business process knowledge while being clear about technical consequences.
How the SAP Developer interview runs
Usually a screen with a hiring manager or SAP lead, then a technical interview on ABAP and the parts of the SAP landscape the team uses, which may be classic ABAP on ECC, ABAP on S/4HANA with CDS views, or the newer RESTful application programming model. Expect questions on performance, enhancements and the transport process. Many interviews include a scenario about a slow report or a custom change that must survive an upgrade, and a conversation about working with functional consultants who own the business process.

Common questions in every interview
These come up in almost every SAP Developer interview regardless of the company or the round.
- 8.
Tell me about yourself.
Why they ask it: Opens the interview and sets the frame. The interviewer is checking whether you can select what matters for this job rather than narrate your whole history.
A strong answer: A 60-90 second arc: where you are now, one or two proof points that match the posting, and why this role is the logical next step. Present, past, then future.
- 9.
Why do you want this role?
Why they ask it: Tests whether you read the job description or mass-applied. Weak answers are about what the candidate gets; strong answers connect to the work itself.
A strong answer: Two specifics from the posting or the company's actual work, plus an honest line about what you want to get better at here.
- 10.
Walk me through your resume.
Why they ask it: Checks that your story holds together and that the transitions were deliberate rather than accidental.
A strong answer: Chronological but fast, with a reason attached to each move and more time on the roles closest to this one.
- 11.
Tell me about a time you failed.
Why they ask it: Tests self-awareness and whether you own outcomes. Interviewers are listening for a real failure, not a disguised strength.
A strong answer: A genuine miss, what you specifically got wrong, the cost, and the concrete thing you changed afterwards that has since held up.
- 12.
Tell me about a conflict with a coworker or manager.
Why they ask it: Predicts how you behave when the team disagrees. The trap is blaming the other person.
A strong answer: The substance of the disagreement, what you did to understand their position, how it resolved, and what the working relationship looked like after.
- 13.
What's your greatest strength?
Why they ask it: Checks whether you know what you're actually good at and can prove it.
A strong answer: One strength that maps to the posting, plus a short example where it produced a measurable result.
- 14.
What's your greatest weakness?
Why they ask it: Tests honesty and whether you're actively working on something. Rehearsed non-answers ('I work too hard') read as evasive.
A strong answer: A real limitation that isn't core to the job, the system you built to manage it, and evidence it's improving.
- 15.
Tell me about a time you had to influence someone without authority.
Why they ask it: Almost every role depends on getting people who don't report to you to change course.
A strong answer: What you wanted, why they resisted, the evidence or framing that moved them, and what actually shipped as a result.
- 16.
Where do you see yourself in five years?
Why they ask it: Tests whether this job fits your trajectory, which is a retention question in disguise.
A strong answer: A direction rather than a title, and a line about the skills this role would build toward it. Vague ambition and rigid title-chasing both land badly.
- 17.
Why are you leaving your current job?
Why they ask it: Screens for red flags. Interviewers listen for how you talk about people you no longer work with.
A strong answer: Forward-looking and specific about what you're moving toward. Criticism of a former employer costs you more than it gains, even when it's deserved.
- 18.
What are your salary expectations?
Why they ask it: Checks whether you've done market research and whether you're in range before anyone spends more time.
A strong answer: A researched range with your target near the bottom of it, framed against the scope of the role. Deflect once if the posting has no band, then answer.
- 19.
Do you have any questions for us?
Why they ask it: The most under-prepared question in the interview, and the one that most changes the final impression.
A strong answer: Two or three questions about how the team actually works: what the first 90 days look like, how success is measured, what the hardest part of the job is.
