How interviewers test your communication and preparation right from the start.
Walk me through your ERP technical career.
I've been an ERP technical consultant for nine years, four in Oman. Started with ABAP development in India, expanded to multi-ERP technical work, and for the past three years I've been ERP technical consultant at an Omani enterprise. My remit: technical development across our ERP estate (SAP, Oracle), integrations, custom extensions, performance work. Languages: ABAP, PL/SQL, Java for integrations. ERPs vary; technical principles are common.

Past-experience questions. Use the STAR framework: Situation, Task, Action, Result.
Tell me about a complex technical project.
Last year I built a custom integration between SAP S/4HANA and our legacy banking system: real-time financial postings via SAP REST APIs, error handling, reconciliation. Three months of work. Integration runs reliably with comprehensive error handling. ERP integration succeeds on engineering discipline; shortcuts here produce daily operational issues.
Integration delivery.
Describe a performance issue.
Long-running batch job in SAP affecting other processing. Profiled: inefficient SELECT statements, missing indexes for our data patterns, suboptimal ABAP code. Refactored. Runtime reduced 70%. ERP performance work is engineering applied to large data volumes; ignored performance becomes operational pain.
Performance engineering.
Tell me about pushing back on a request.
Business asked for extensive customisation in SAP for a marginal business benefit. I proposed instead a configuration-based approach with reduced flexibility but no customisation. Adopted. ERP customisation discipline is technical role's value; just executing requests as given creates maintenance burden.
Customisation discipline.

Technical & role-specific
Questions that test your specific skills for this role.
Walk me through your development approach.
Naming conventions and code organisation per ERP standards. Performance-aware: large data volumes are normal in ERP. Modular design. Documentation maintained. Code review by another developer. Testing rigorous: unit, integration, performance. Deployment through proper change control. Discipline pays back over the asset's life.
Real methodology.
Describe ABAP best practices.
Avoid SELECT * - specify fields. Use indexes effectively (analyse query plans). Read tables for direct access, loop only when needed. FOR ALL ENTRIES with care (handle empty internal table). Buffering on table reads where appropriate. Performance is part of ABAP craft; lazy code produces slow programs.
ABAP performance.
How do you handle PL/SQL in Oracle ERP?
Package-based organisation. Bulk processing for large data sets. Bind variables to avoid hard parsing. Indexes verified for query patterns. Exception handling proper. Logging adequate. PL/SQL in Oracle ERP context follows similar principles as standalone PL/SQL plus ERP-specific patterns (concurrent programs, AOL).
PL/SQL depth.
Category
Situational
Hypothetical scenarios designed to test your judgement and approach.
A production issue needs urgent technical investigation. What do you do?
Investigate methodically even under pressure. Diagnose before acting. Mitigate if straightforward fix available. Full fix through proper change. Post-incident review on root cause. Urgent investigation done well produces both quick recovery and learning; rushed investigation produces wrong fixes.
Urgent issue discipline.

Cultural fit & motivation
Why this role, why this company, and how you work with others.
How do you work with functional consultants?
Functional consultants own business design; my role is implementing them technically. Joint design reviews catch issues early. I respect their domain knowledge; they respect technical concerns. Documentation of decisions for institutional memory.
Cross-discipline work.

Closing
The final stretch. Often where deals are won or lost.
What are your salary expectations?
For a senior ERP technical consultant role at an Omani enterprise I'd target OMR 1,800 to 2,400 total package depending on stack diversity and integration scope. Multi-ERP capability commands a premium. I'd expect annual bonus and certification budget. I'm on 60 days' notice. Beyond pay I'd value the team's modernisation trajectory.
