System Architecture & Domain Knowledge

For intermediate and senior roles, you will be evaluated on your ability to design reliable systems that operate at scale. You must show that you can think beyond the code and understand how services interact.

Be ready to go over:

• Microservices & APIs – Designing clean RESTful or GraphQL APIs, handling authentication, rate limiting, and data serialization.
• Cloud & DevOps – Deploying applications using cloud services, containerization (Docker/Kubernetes), and continuous integration pipelines.
• State Management & Databases – Choosing the right database technology, designing schemas, and managing state in distributed systems.
• Advanced concepts (less common) – Event-driven architectures, message queues (Kafka/RabbitMQ), and caching strategies (Redis) for high-availability systems.

Example scenarios:

• "How would you design a scalable notification system that can handle millions of push notifications, emails, and SMS messages daily?"
• "Walk me through the architecture of a web application that must remain highly available even during regional cloud outages."

Behavioral & Team Integration

This evaluation area focuses on how you work within a team, handle challenges, and align with the organizational culture of TELUS Digital.

Be ready to go over:
