2. Explain the difference between Incident, Problem, and Change Management in ServiceNow.

Why this question matters: This tests your understanding of fundamental ITSM concepts and how they're implemented within ServiceNow. It's crucial to demonstrate you know the difference between these core processes.

How to answer:

"In ServiceNow, Incident, Problem, and Change Management are distinct but interconnected processes:

• Incident Management: Focuses on restoring normal service operation as quickly as possible after an incident occurs. An incident is an unplanned interruption to an IT service or a reduction in the quality of an IT service. The goal is to minimize the impact on the business. Example: A user can't access their email.
• Problem Management: Focuses on identifying the underlying cause of one or more incidents and preventing future occurrences. A problem is the underlying cause of one or more incidents. The goal is to identify and resolve the root cause of problems to prevent future incidents. Example: Recurring email outages are traced to a faulty server.
• Change Management: Focuses on managing the process of implementing changes to the IT infrastructure in a controlled and standardized way. A change is the addition, modification, or removal of anything that could affect IT services. The goal is to minimize the risk associated with changes. Example: Upgrading the email server software.

In short, incident management gets things back up and running, problem management figures out why it broke in the first place, and change management makes sure future changes don't break things."

Pro Tip: Use real-world examples to illustrate your understanding. This makes your answer more relatable and shows you can apply the concepts.

3. What is a Business Rule in ServiceNow? Give an example.

Why this question matters: Business rules are a cornerstone of ServiceNow development. This question assesses your understanding of how to automate processes and enforce business logic within the platform.

How to answer:

"A business rule in ServiceNow is a server-side script that runs when a record is displayed, inserted, updated, or deleted. They're used to automate tasks, enforce business policies, and ensure data integrity. Business rules allow you to customize the behavior of the platform without modifying the core code.

Example: Let's say you want to automatically set the priority of an incident to 'High' if the impact is 'Critical' and the urgency is 'High.' You could create a business rule that runs before an incident is inserted or updated. The script would check the impact and urgency fields and, if both are 'High,' set the priority field to 'High.' This ensures that critical incidents are always given the appropriate priority."

Pro Tip: When giving an example, try to choose a scenario that's easily understandable and demonstrates a practical use case. Also, mention that business rules run on the server-side.

4. What are Client Scripts in ServiceNow? What are the different types?

Why this question matters: Client scripts are the counterpart to business rules, running on the client-side (the user's browser). Understanding them is crucial for creating interactive and user-friendly interfaces.

How to answer:

"Client scripts are scripts that run on the client-side, within the user's web browser. They're used to manipulate the user interface, validate data, and enhance the user experience. Unlike business rules, which run on the server, client scripts execute in real-time as the user interacts with the form.

There are four main types of client scripts:

• OnLoad: Executes when a form is loaded.
• OnChange: Executes when a specific field value changes.
• OnSubmit: Executes when a form is submitted.
• OnCellEdit: Executes when a cell in a list is edited.

Example: An onChange client script could be used to automatically populate a field based on the value selected in another field. An onSubmit client script could be used to validate that all required fields are filled out before the form is submitted."

Pro Tip: Be sure to specify that client scripts run in the browser. Also, knowing when to use a client script versus a business rule is a key differentiator.

5. Explain what a GlideRecord is and how it's used.

Why this question matters: GlideRecord is the primary way to interact with the ServiceNow database. Understanding it is essential for any ServiceNow developer.

How to answer:

"GlideRecord is a Java class in ServiceNow that allows you to query and manipulate data in the ServiceNow database. It's the primary way to interact with tables and records within the platform. Think of it as an object that represents a database table.

Using GlideRecord, you can:

• Query for records: Retrieve records that match specific criteria.
• Create new records: Insert new records into a table.
• Update existing records: Modify the values of existing records.
• Delete records: Remove records from a table.

Example: To retrieve all active incidents, you would create a GlideRecord object for the 'incident' table, set the 'active' field to 'true', and then execute the query. You can then iterate through the results and access the values of each field in each incident record."

Pro Tip: Mention the methods used with GlideRecord, such as query(), next(), update(), insert(), and delete(). This shows a deeper understanding.

6. What is a Workflow in ServiceNow? Give an example of how you might use one.

Why this question matters: Workflows are used to automate complex processes in ServiceNow. This question assesses your ability to design and implement automated solutions.

How to answer:

"A workflow in ServiceNow is a sequence of activities that automate a process. It's a visual representation of a process, allowing you to define the steps, conditions, and approvals required to complete a task.

Example: Imagine a new employee onboarding process. A workflow could be used to automate the following steps:

1. HR submits a new employee request.
2. The workflow automatically creates tasks for IT to provision a laptop and accounts.
3. A task is created for facilities to provide a desk and access card.
4. Once all tasks are complete, a notification is sent to the new employee and their manager.

This eliminates manual tasks, ensures consistency, and provides visibility into the onboarding process."

Pro Tip: When describing a workflow, focus on the business value it provides. Highlight how it automates tasks, reduces errors, and improves efficiency.

7. What are Update Sets in ServiceNow and how are they used?

Why this question matters: Update sets are crucial for managing and deploying changes in ServiceNow. Understanding them is essential for any administrator or developer.

How to answer:

"Update sets are a mechanism in ServiceNow for grouping and moving customizations from one instance to another. They capture changes made to the platform, such as new business rules, client scripts, workflows, and other configurations. This allows you to develop and test changes in a development instance and then migrate them to a production instance without manually recreating them.

How they're used:

1. You create an update set and make it the current update set.
2. You make your changes (e.g., create a new business rule).
3. ServiceNow tracks all the changes you make in that update set.
4. Once you're done, you complete the update set.
5. You then export the update set as an XML file.
6. In the target instance (e.g., production), you retrieve the update set and preview the changes.
7. If everything looks good, you commit the update set, applying the changes to the target instance."

Pro Tip: Mention the importance of testing update sets in a non-production environment before deploying them to production. This shows you understand the importance of change management.

8. Explain the purpose of the Service Catalog in ServiceNow.

Why this question matters: The Service Catalog is a key component of ServiceNow, providing a self-service portal for users to request services and items. This question assesses your understanding of its role in improving user experience and streamlining service delivery.

How to answer:

"The Service Catalog in ServiceNow provides a user-friendly interface for requesting services, hardware, software, and other items. It's essentially an online store for IT and other departments, allowing users to easily find and request the things they need. The Service Catalog streamlines the request process, automates fulfillment, and provides a central repository for all available services.

The purpose of the Service Catalog is to:

• Improve user experience: Provides a self-service portal that's easy to use and navigate.
• Streamline service delivery: Automates the request and fulfillment process, reducing manual effort and improving efficiency.
