Walk me through your technical architect career.
I've been a technical architect for nine years, four in Oman. Started as a developer at an Indian software firm, progressed through senior developer and tech lead, and for the past three years I've been technical architect at an Omani enterprise. My remit: technical design across projects, technology selection, integration patterns, performance design. Stack spans Java, .NET, Python, plus relational and NoSQL databases, plus cloud platforms. AWS architect, plus broader tech credentials.

Past-experience questions. Use the STAR framework: Situation, Task, Action, Result.
Tell me about a complex design you delivered.
Last year I designed a customer service platform: integration with our CRM, telephony, customer-data, knowledge base. Multiple integration patterns combined: REST APIs for synchronous, events for cross-service updates, webhooks for telephony. Twelve months delivery. Platform serves agents productively. Integration architecture is where many projects struggle; getting the patterns right pays back in operational stability.
Real design.
Describe a technology selection.
Project needed a search capability. Options: Elasticsearch, Solr, or PostgreSQL full-text search. I led evaluation: requirements, peer experience, operational considerations, cost. Recommendation: PostgreSQL full-text for current scale (already had Postgres expertise, operational simplicity); migration to Elasticsearch path defined if scale demands. Selection still serves; sometimes the boring choice is the right one.
Selection judgement.
Tell me about a design that didn't work.
Designed an asynchronous workflow pattern for a project that turned out to need synchronous user feedback. We discovered during user testing that the async pattern produced confusing UX. Redesigned to synchronous-with-progress-indicator. Lesson: validate UX assumptions with users before committing to async patterns; technical elegance shouldn't override user experience needs.
Honest learning.

Technical & role-specific
Questions that test your specific skills for this role.
Walk me through your design process.
Requirements clarified; technical and functional both. Options identified with explicit tradeoffs. Decision driven by requirements not preferences. Documentation: design rationale, key decisions, alternatives considered. Review with team and senior architects. Communicate to delivery team. Iterate as implementation reveals issues. Design serves the project; rigid early designs that ignore implementation reality fail.
Real design methodology.
Describe your approach to integration patterns.
Pattern catalogue per use case. Synchronous REST for direct request-response with user-visible latency. Async events for state propagation across services. Webhooks for inbound from external systems. Batch for high-volume periodic. Choose pattern per requirement, not by default. Document choices for institutional memory. Integration patterns chosen well produce stable systems; chosen badly produce constant trouble.
Integration depth.
How do you handle scalability design?
Growth assumptions documented explicitly. Bottleneck analysis: where would the system constrain first under growth. Design to scale that dimension: horizontal where stateless, sharding where stateful, caching where read-heavy. Test scalability with realistic load profiles. Plan for the next constraint after the first is addressed. Scalability isn't infinite scaling; it's removing the next bottleneck at appropriate cost.
Scalability methodology.

Situational
Hypothetical scenarios designed to test your judgement and approach.
A new technology emerges that could change the architecture. How do you respond?
Investigate honestly: what does it actually do, how mature, what's the adoption picture. Evaluate against current pain points: does it solve real problems we have. Pilot if promising. Adopt only when value is clear and risk is manageable. Resist hype but don't reject genuine innovation. Architecture evolves; the discipline is intentional evolution.
Mature tech adoption.

Cultural fit & motivation
Why this role, why this company, and how you work with others.
How do you work with delivery teams?
Teams own delivery; architecture supports them. I'm available for design questions throughout, not just at sign-off. I'm responsive. I'm pragmatic when reality differs from design. The relationship matters; architects who help teams ship get engaged.
Service mindset.

Closing
The final stretch. Often where deals are won or lost.
What are your salary expectations?
For a senior technical architect role at an Omani enterprise I'd target OMR 2,800 to 3,800 total package depending on portfolio scope and stack diversity. Roles with significant transformation responsibility pay more. I'd expect annual bonus and certification budget. I'm on 60-90 days' notice. Beyond pay I'd value the team's modernisation commitment.
