About your past

As a player-coach-architect, how do you split your time between writing code, guiding the team and setting architecture?

What they are checking: Whether they can stay hands-on without neglecting team leadership or long-term design.

Tell me about a cloud platform you moved toward a better architecture while it was still in production.

What they are checking: Whether they can evolve live systems safely without big-bang rewrites.

How do you grow senior engineers into architects?

What they are checking: Whether they deliberately develop technical leaders, not just individual contributors.

What would you do

A product team wants a new feature fast, but it would add serious technical debt. How do you handle it?

What they are checking: Whether they can negotiate trade-offs and make debt visible to business leaders.

Three business units use the same platform with different needs. How do you design for shared use without slowing each one down?

What they are checking: Whether they can build a common platform with clean extension points for each business.

About the work

Walk me through how you'd architect an Azure IoT platform that takes telemetry from thousands of fire, refuse and mixer trucks.

What they are checking: Whether they can design ingestion, storage, processing and scaling for connected vehicles end to end.

Trucks lose connectivity in rural areas and inside buildings. How does your design handle that?

What they are checking: Whether they plan for store-and-forward, idempotent ingestion and out-of-order data.

How do you secure a fleet of connected vehicles, from device identity to the cloud?

What they are checking: Whether they think about device provisioning, certificates, least privilege and update security.

This equipment is mission critical for first responders. How does that change your approach to reliability and monitoring?

What they are checking: Whether they set real reliability targets, alerting and incident practices for critical users.

How do you keep cloud costs under control as data volume grows?

What they are checking: Whether they think about data tiering, retention, sampling and cost visibility.

How do you decide between managed Azure services and building something yourselves?

What they are checking: Whether they weigh cost, lock-in, team skills and speed when making platform choices.
