Walk me through your MDM career.
I've been on Informatica MDM for seven years, three in Oman. Started in data quality at an Indian SI, transitioned to MDM, and for the past three years I've been Informatica MDM senior consultant at an Omani Tier-1 bank. My remit: customer MDM platform covering 4M+ customer records, golden record management, integration with source systems and consuming applications. Informatica MDM certifications.

Tell me about an MDM implementation.
Two years ago I led the customer MDM implementation: consolidation from five source systems, golden record creation, match-merge logic, data steward workflows, integration with consuming applications. Eighteen months of work. Outcome: customer view unified; downstream systems served by single source of truth. MDM done well transforms how organisations think about customers; done poorly creates another inconsistent data store.
Real MDM delivery.
Describe a data quality issue.
Match-merge logic was creating false matches: customers with similar names being merged incorrectly. Tuned: matching rules refined with stronger weights on secondary identifiers, threshold adjusted, human review for borderline cases. False match rate dropped to acceptable level. MDM matching is judgement-intensive; theory meets messy real-world data.
Quality engineering.
Tell me about working with business stewards.
Data stewards have business knowledge MDM needs; their feedback shapes data quality and matching rules. I respect their domain expertise. I'm direct on technical constraints. Stewardship workflow designed for their reality. The relationship matters; stewards who feel heard engage productively.
Stewardship partnership.

Technical & role-specific
Questions that test your specific skills for this role.
Walk me through MDM architecture.
Hub-based architecture: customer hub as the system of record. Source systems push data via standardised feeds. Match-merge produces golden records. Data steward workflows for exceptions. Consumption via APIs and event-based propagation to downstream. Architecture serves multiple consumers; designing for current need plus expected evolution.
MDM architecture.
Describe your match-merge approach.
Matching rules per entity type. Weights per attribute based on discriminating power. Thresholds tuned to optimise true positive vs false positive. Automated vs human review per threshold zone. Cleansing and standardisation upstream of matching. Match-merge is engineering applied to fuzzy identity; rules pay back over years.
Match-merge depth.
How do you handle survivorship?
Survivorship rules per attribute: which source wins, what date rule applies, what completeness consideration. Documented for transparency. Steward override capability for exceptions. Survivorship logic that's clear is maintainable; opaque survivorship creates trust issues with consuming applications.
Survivorship.

Situational
Hypothetical scenarios designed to test your judgement and approach.
A consuming application reports stale data. What do you do?
Investigate the propagation: source update timing, hub processing, downstream delivery. Identify where the delay or failure occurred. Fix the immediate issue. Address systemic cause: faster propagation if needed, better monitoring on delivery. MDM consumers depend on timely data; staleness erodes trust.
Operational rigour.
Category
Cultural fit & motivation
Why this role, why this company, and how you work with others.
How do you handle multilingual / cross-cultural data?
Arabic and English names common in Omani context. Transliteration handling. Multi-script support in matching. Cultural naming patterns considered (single names, family names, regional variations). Standardisation rules respect data variety while enabling matching.
Local-context awareness.

Closing
The final stretch. Often where deals are won or lost.
What are your salary expectations?
For a senior Informatica MDM consultant role at an Omani Tier-1 bank I'd target OMR 2,000 to 2,600 total package depending on platform scope. MDM specialism is in limited supply. I'd expect annual bonus and certification budget. I'm on 60 days' notice. Beyond pay I'd value the bank's data strategy.
