• Advanced concepts (less common) – Event sourcing, CQRS (Command Query Responsibility Segregation) patterns, and cloud-native serverless architectures.

Example questions or scenarios:

• "Design a real-time notification system capable of sending millions of push notifications, emails, and SMS messages daily with low latency."
• "How would you migrate a monolithic billing application to a microservices architecture without causing system downtime?"

Presentation & Whiteboarding

Many candidates face a dedicated presentation round where they must present an architectural solution or their career history to a panel of senior leaders. This round evaluates your executive presence, communication clarity, and ability to handle live, challenging questions.

Be ready to go over:

• Enterprise Architecture Delivery – Presenting a high-level architecture diagram and defending your technology choices.
• Whiteboard Problem Solving – Designing an application live on a whiteboard while explaining your thought process step-by-step.
• Stakeholder Management – Translating highly technical concepts into business value for non-technical executives.
• Advanced concepts (less common) – Explaining how the Pega Platform integrates with existing enterprise architectures to drive digital transformation.

Example questions or scenarios:

• "Present an architecture you previously designed, explain the alternatives you considered, and justify why you chose that specific stack."
• "Use the whiteboard to design a system that automates claims processing for an insurance company, ensuring high security and auditability."

Logical Reasoning & Puzzles

Pegasystems frequently uses puzzles and lateral thinking questions to evaluate how you react when confronted with unfamiliar, ambiguous, or seemingly impossible problems.
