IndiaQ1. What is a business process in Workday and why is it central?
Short answer: A configurable sequence of steps (actions, approvals, conditions) that drives transactions.
Strong answer: A Business Process (BP) is Workday’s configurable workflow — a sequence of steps like initiation, approvals, to-dos, conditions and notifications — that governs transactions (hire, change job, etc.). Almost everything in Workday runs through BPs, and security and routing attach to them, so understanding BP configuration is core to Workday work.
Likely follow-up: How does security interact with business process steps?
What the interviewer is checking: Core Workday concept.
Common mistake: Treating Workday like a static form app rather than BP-driven.
Q2. Explain Workday security: domain vs business process security.
Short answer: Domain security controls data/task access; BP security controls who can act on process steps.
Strong answer: Domain security policies grant view/modify access to data and tasks grouped into functional domains. Business process security policies control who can initiate, approve or act on BP steps. Both are assigned to security groups, and changes require activating pending security. Getting this right is critical and a frequent interview focus.
Likely follow-up: What must you do after editing a security policy?
What the interviewer is checking: Security model understanding.
Common mistake: Forgetting to activate pending security changes.
Q3. What are the main types of Workday reports?
Short answer: Standard (delivered), custom (Advanced, Matrix, Composite, Trending) built in the report writer.
Strong answer: Workday has delivered standard reports and custom reports built in the report writer: Simple, Advanced (most common, supports prompts/sharing/exposing as web service), Matrix (aggregations), Composite (financial-style), and Trending. Choosing the right type and data source (with the correct business object) is key to reporting.
Likely follow-up: Which report type would you expose as a web service for integration?
What the interviewer is checking: Reporting knowledge.
Common mistake: Using the wrong report type or data source.
Q4. What are calculated fields and where are they used?
Short answer: Reusable fields that derive values, used in reports, integrations and conditions.
Strong answer: Calculated fields derive new values from existing data using functions (lookup, arithmetic, date, text, evaluate expression) and are reusable across reports, integrations, business process conditions and condition rules. They are powerful but can impact performance, so build them efficiently and reuse rather than duplicate.
Likely follow-up: Why can complex calculated fields hurt report performance?
What the interviewer is checking: Practical configuration skill.
Common mistake: Overusing heavy calculated fields and duplicating logic.
Q5. How does Workday handle configuration vs customization?
Short answer: Workday is configured (no custom code); updates are seamless because you don’t modify core code.
Strong answer: Workday is configured through tenant setup — business processes, security, reports, calculated fields, EIB/integrations — not custom-coded like on-prem ERPs. This is why twice-yearly updates apply without breaking customizations. "Customization" in Workday means configuration and integrations, so upgrade impact is much lower.
Likely follow-up: Why do Workday’s two annual updates rarely break tenants?
What the interviewer is checking: Platform philosophy.
Common mistake: Expecting code-level customization like legacy ERPs.
Q6. How are integrations built in Workday?
Short answer: EIB for simple, Core Connectors for packaged, and Studio for complex integrations.
Strong answer: EIB (Enterprise Interface Builder) handles simple inbound/outbound data via templates. Core Connectors are pre-built for common integrations (payroll, benefits). Workday Studio builds complex, custom integrations with transformations. All leverage Workday web services (SOAP/REST) and reports-as-a-service. Choose by complexity.
Likely follow-up: When would you move from EIB to Studio?
What the interviewer is checking: Integration approach.
Common mistake: Forcing complex logic into an EIB that needs Studio.
