Here is a list of basic-level Pega interview questions and answers:
- What is Pega, and how is it different from traditional programming?
Pega is a low-code platform designed for building business applications, automating workflows, and managing case lifecycles. Unlike traditional programming, which requires extensive coding, Pega uses a model-driven approach with reusable rules, making development faster. It provides built-in tools for BPM, CRM, and AI-based decisioning, reducing dependency on manual coding and customization.
- What are the key components of the Pega platform?
Pega consists of several core components:
- Case Management – Helps define, manage, and track work.
- Decisioning & AI – Supports real-time analytics for customer interactions.
- Process Automation – Uses flows, rules, and integrations to automate business logic.
- UI & User Experience – Offers responsive UI components.
- Integration & Data – Connects with external databases, APIs, and legacy systems.
- What is a case in Pega, and how is it managed?
A case in Pega represents a business process or workflow, such as processing a loan application. Cases have stages, steps, and tasks that define their lifecycle. Pega manages cases through case types, which define workflows, data dependencies, and automation rules. Cases can be dynamically routed, assigned, and escalated based on business logic.
- What are the different types of rules in Pega?
Rules in Pega define application behavior and are categorized into:
- Process Rules – Define workflows (e.g., Flow Rules, Flow Actions).
- Decision Rules – Control business logic (e.g., Decision Tables, When Rules).
- UI Rules – Manage user interface (e.g., Sections, Harnesses).
- Declarative Rules – Automate logic execution (e.g., Declare Expressions, Constraints).
- Integration Rules – Connect with external systems (e.g., Connect REST, Connect SQL).
Pega Interview Questions for Freshers
Here are some commonly-asked Pega interview questions and answers for freshers:
- How does Pega support low-code development?
Pega offers a visual, model-driven development approach, reducing the need for extensive coding. Developers use drag-and-drop tools, rule-based automation, and built-in templates to configure applications. Pega’s App Studio allows business users to define workflows without writing code, speeding up development.
- What is a rule in Pega, and how does it work?
A rule in Pega is a reusable logic component that defines system behavior. Rules control data processing, UI design, workflows, and decision-making. Pega uses rule resolution, an intelligent mechanism that selects the most relevant rule based on class hierarchy, versioning, and availability.
- Explain the difference between a flow action and a connector in Pega.
A flow action determines what a user can do at an assignment, such as submitting or saving data. A connector defines how the process transitions from one step to another based on conditions. Flow actions guide user interaction, while connectors control process flow.
- What are work objects in Pega, and how are they stored?
A work object (now called a “case”) represents a unit of work processed in a Pega application. It includes case data, history, and status. Work objects are stored in Pega’s database, typically in tables like pc_work for active cases and pc_history_work for audit logs.
Pega Interview Questions for Experienced
Let’s go through the important interview questions on Pega for experienced candidates:
- What is the difference between case management and business process management (BPM) in Pega?
BPM focuses on process automation, using structured workflows to handle repetitive tasks efficiently. Case Management, on the other hand, manages complex, dynamic workflows where actions depend on real-time data and human decisions. Pega’s Case Lifecycle Management supports both structured and unstructured processes, allowing flexibility in business operations.
- How do you debug and troubleshoot performance issues in a Pega application?
“To diagnose performance issues, I use Pega Tracer to log rule execution and find delays. Performance Analyzer (PAL) helps track system performance, including database queries and memory usage. Clipboard Tool provides insights into data loading and processing inefficiencies. For long-running processes, I check Declarative Indexing, Data Page Refresh Strategies, and Asynchronous Processing.”
- What is rule resolution, and how does Pega determine which rule to execute?
Rule resolution is the process Pega uses to find the most appropriate rule at runtime. It considers factors such as class hierarchy, rule availability, versioning, and circumstancing. If multiple rules match, Pega applies the best-fit rule based on priority.
- Explain the significance of Declare Expressions in Pega.
A Declare Expression is a declarative rule that automatically updates a property’s value based on changes in related fields. It eliminates the need for manual calculations in workflows, improving performance and maintainability. Declare Expressions operate without requiring explicit execution, ensuring real-time updates.

Advanced Pegasystems Interview Questions
These are some advanced Pegasystems interview questions and answers:
- What is the difference between Pega’s case type hierarchy and traditional object-oriented inheritance?
In Pega’s case type hierarchy, parent and child case types share behaviors, but each case type can have independent processing logic. Case relationships focus on business workflows rather than code reuse. In traditional object-oriented inheritance, child classes inherit methods and properties from parent classes, primarily for code reuse and structure. Pega’s approach is more flexible, allowing rule specialization without strict dependency on parent structures.
- How does Pega’s Decision Strategy Manager (DSM) work?
DSM in Pega is a framework for real-time decision-making using predictive analytics, adaptive models, and decision tables. It helps businesses create personalized customer interactions by analyzing historical data and refining strategies dynamically. DSM uses Next-Best-Action (NBA) logic, considering customer preferences, business objectives, and contextual data to recommend the most relevant action.
- What is a node-level data page, and how is it different from a requestor-level data page?
A node-level data page is shared across all users on a specific node, improving efficiency for frequently accessed data like reference lists. A requestor-level data page is specific to a user session, storing user-specific data without affecting other users. Node-level pages reduce redundancy, while requestor-level pages prevent data conflicts.
Pega Interview Questions Scenario Based
You must also prepare for scenario-based interview questions on Pega:
- You need to create a custom authentication mechanism in Pega. How would you approach this?
“I would use Custom Authentication Services in Pega. First, I would create an Authentication Service rule and configure it to accept user credentials from an external source like LDAP, OAuth, or SAML. Next, I would implement a custom Java activity to validate user input and set authentication tokens. Finally, I would update Access Groups and Roles to define user permissions upon successful authentication.”
- If a rule does not execute as expected, how do you troubleshoot it?
“I start by using Pega Tracer to track rule execution. Then, I check the Clipboard tool to verify property values and confirm data correctness. If rule resolution is a concern, I inspect rule versioning, class hierarchy, and circumstancing. Additionally, I review logs (PegaRULES, PegaALERT, PegaSECURITY) for error details and identify potential performance bottlenecks.”
- A business requirement demands that a specific case be locked to prevent multiple users from updating it simultaneously. How would you implement this?
“Pega automatically applies optimistic and default locking mechanisms. If strict locking is required, I would configure default locking, where only one user can edit a case at a time. If a shared editing mode is needed, I would implement optimistic locking, allowing multiple users to work but restricting updates if data conflicts occur.”
Interview Questions for Pega Developer
Here are some interview questions on Pega for developers:
- What are the different types of class structures in Pega?
Pega follows the Enterprise Class Structure (ECS), which includes:
- Organization Class – Common assets across the organization.
- Division Class – Used for business unit-specific rules.
- Implementation Class – Application-specific components.
- Framework Class – Reusable rules for multiple applications.
- How do you implement parallel processing in Pega workflows?
Parallel processing is achieved using Split-Join, Split-For-Each, and Parallel Flows:
- Split-Join: Runs multiple sub-processes simultaneously and waits for completion.
- Split-For-Each: Iterates over a collection and processes each item concurrently.
- Parallel Flows: Allows different stages of a case to execute simultaneously.
- What is the significance of data propagation in case types?
Data propagation allows parent cases to share information with child cases. This helps maintain consistency and reduces redundant data entry. It is configured using Data Transform rules, allowing automatic data transfer between related cases.
