Category

Opening & warm-up

How interviewers test your communication and preparation right from the start.

Walk me through your ERP technical career.

Sample answer

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.

What they're really listening for

Technical scope.

Category

Behavioural (STAR)

Past-experience questions. Use the STAR framework: Situation, Task, Action, Result.

Tell me about a complex technical project.

Sample answer

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.

What they're really listening for

Integration delivery.

Describe a performance issue.

Sample answer

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.

What they're really listening for

Performance engineering.

Tell me about pushing back on a request.

Sample answer

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.

What they're really listening for

Customisation discipline.

Category

Technical & role-specific

Questions that test your specific skills for this role.

Walk me through your development approach.

Sample answer

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.

What they're really listening for

Real methodology.

Describe ABAP best practices.

Sample answer

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.

What they're really listening for

ABAP performance.

How do you handle PL/SQL in Oracle ERP?

Sample answer

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).

What they're really listening for

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?

Sample answer

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.

What they're really listening for

Urgent issue discipline.

Category

Cultural fit & motivation

Why this role, why this company, and how you work with others.

How do you work with functional consultants?

Sample answer

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.

What they're really listening for

Cross-discipline work.

Category

Closing

The final stretch. Often where deals are won or lost.

What are your salary expectations?

Sample answer

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.

What they're really listening for

Range and trajectory preference.
