ServiceNow Interview Questions And Answers
Question 1: What is ServiceNow, and how does it work?
Answer: ServiceNow is a powerful cloud-based platform that offers a range of IT service management (ITSM) solutions. It provides a consolidated view of various IT processes, enabling organizations to automate workflows, streamline operations, and enhance service delivery. With ServiceNow, teams can easily manage incidents, change requests, problem tickets, and more.
Imagine a large organization with multiple departments. ServiceNow acts as the central nervous system, seamlessly connecting these departments and their respective processes. For instance, if a user encounters a software issue, they can submit an incident ticket through the ServiceNow portal. ServiceNow then assigns the ticket to the appropriate IT technician, who resolves the issue and updates the ticket. This integrated approach ensures efficient and transparent communication across the entire organization.
Question 2: How can you extend the functionality of ServiceNow?
Answer: ServiceNow offers various extension points to customize and extend its capabilities. Some notable methods include:
One way to extend ServiceNow is through the creation of custom applications. Let’s say a company wants to automate its employee onboarding process. By developing a custom application on the ServiceNow platform, they can create tailored workflows, forms, and business rules specific to their onboarding requirements. This custom app seamlessly integrates with the existing ServiceNow modules, offering a unified experience to users.
Question 3: What is the significance of CMDB (Configuration Management Database) in ServiceNow?
Answer: The CMDB is a fundamental component of ServiceNow, serving as a centralized repository for storing information about configuration items (CIs). CIs can be hardware, software, network devices, or any other item that is part of the IT infrastructure.
Imagine a scenario where a critical server fails unexpectedly. By referring to the CMDB, ServiceNow can quickly identify the affected server, the applications relying on it, and the users impacted. This allows IT teams to respond swiftly, minimizing downtime and ensuring smooth business operations.
Question 4: How does ServiceNow handle automation and orchestration?
Answer: ServiceNow’s Automation and Orchestration module enables organizations to automate manual tasks and streamline complex workflows. It helps reduce operational costs, improve efficiency, and enhance service delivery.

Using ServiceNow’s Automation and Orchestration module, you can create a workflow that automates the entire process. The workflow can involve various tasks, such as requesting resources, verifying approvals, provisioning the VM, and notifying the user upon completion. This automation eliminates the need for manual intervention, reduces errors, and accelerates the provisioning process.

Question 10: What is the difference between a Business Rule and a Script Included in ServiceNow?
Answer: Business Rule:
- Business Rules are server-side scripts that run when specific conditions are met.
- They operate at the database level and trigger actions, such as updating records, setting field values, or displaying messages.
- Business Rules are designed to execute automatically and can be configured to run before or after record operations (insert, update, delete).
- They are useful for enforcing data consistency, implementing validations, or performing calculations during record operations.
- Script Includes are reusable server-side scripts that can be called from various client or server-side scripts.
- They encapsulate a set of functions and can be utilized across multiple applications or modules within ServiceNow.
- Script Includes promoting code modularity, reusability, and maintainability.
- They are commonly used for complex business logic, data manipulation, or integrations.
Let’s consider a scenario where you want to enforce a business rule that calculates the total cost of a purchase order (PO) based on the quantity and unit price. Additionally, you want to reuse this calculation logic in other areas of the system.
Business Rule: Create a business rule on the Purchase Order table that triggers after an update. In the script, calculate the total cost by multiplying the quantity and unit price fields and updating the Total Cost field on the PO record.
Script Include: Create a script include called “POUtils” with a function named “calculateTotalCost(quantity, unitPrice).” This function performs the calculation and returns the result. In the business rule, call the “calculateTotalCost” function from the script include to update the Total Cost field.
