Walk me through your reporting and integration career.
I've been in data integration and reporting for seven years, three in Oman. Started in BI development at an Indian banking IT firm, expanded into data integration, and for the past three years I've been specialist in Power BI and Oracle Analytics at an Omani enterprise. My remit: data pipelines, reports and dashboards across Power BI and Oracle Analytics Cloud, integration with source systems. Both Microsoft and Oracle Analytics certifications.

Past-experience questions. Use the STAR framework: Situation, Task, Action, Result.
Tell me about an analytics project.
Last year I delivered the executive dashboard suite: KPIs across financial, operational, and customer dimensions; Power BI for the dashboards, Oracle Analytics for the deeper analytical capability. Six months of work. Executive team uses the suite weekly in their meetings. Analytics value is decisions enabled, not dashboards built.
Real analytics delivery.
Describe a data quality issue.
Executive dashboard showed numbers that didn't reconcile to finance's own reports. Investigated: timing difference in data extraction plus a transformation that wasn't matching finance's calculation. Aligned to canonical definition. Reconciliation clean since. Analytics on misaligned data destroys credibility quickly.
Data quality discipline.
Tell me about working with business users.
Business users want answers, not reports. I learn what decisions they make; I design analytics around those. I'm patient with iteration; analytical requirements rarely arrive perfectly defined. The relationship matters.
Business orientation.

Technical & role-specific
Questions that test your specific skills for this role.
Walk me through Power BI development.
Semantic model in Power BI dataset: dimensional structure, calculated columns minimal, DAX measures performant. Visuals chosen per data and question. Performance considered: query reduction, aggregations where helpful. Refresh schedule appropriate. Governance: certified datasets vs personal. Power BI engineering matters; ad hoc reports become inconsistent.
Power BI depth.
Describe Oracle Analytics Cloud.
Data sets prepared with appropriate joins and transformations. Visualisations per business need. Dashboards for operational use. Day-by-Day for mobile. Data flows for pipeline development. Power BI and Oracle Analytics have different strengths; choosing well per use case.
OAC depth.
How do you handle data integration?
Source-to-target mappings documented. ETL or ELT per workload (modern preference is ELT into the warehouse). Incremental loads where data volumes warrant. Error handling and reconciliation. Data lineage maintained. Integration discipline determines analytics quality.
Integration depth.

Situational
Hypothetical scenarios designed to test your judgement and approach.
Business wants a dashboard urgently with limited data validation. What do you do?
Honest conversation: urgent dashboards with poor data quality mislead decisions. Propose: shorter scope with quality validation, or interim version with caveats clearly visible while quality work continues. Don't ship dashboards as if they're certified when they're not; credibility takes years to build, days to destroy.
Quality integrity.
Category
Cultural fit & motivation
Why this role, why this company, and how you work with others.
How do you handle metric inconsistency?
Same metric calculated differently in different reports is common. I drive convergence: canonical definition, certified dataset, education on the distinction where genuine reason for different versions. Metric governance is the discipline that prevents executives seeing different numbers in different rooms.
Metric discipline.

Closing
The final stretch. Often where deals are won or lost.
What are your salary expectations?
For a senior reporting and integration specialist role at an Omani enterprise I'd target OMR 1,600 to 2,200 total package depending on scope and platform diversity. Multi-platform capability commands a premium. I'd expect annual bonus and certification budget. I'm on 30-60 days' notice. Beyond pay I'd value the analytics maturity.
