Hey @shirishakathula ,

This is a Interview question i prepared for my teams for the servicenow,

ServiceNow Scenario-Based Scripting Interview Questions

1. Business Rules

Beginner

Q1. A requirement says: Whenever an Incident is created, automatically populate the Assignment Group based on the Category.

Which Business Rule type would you use?
Would you use Before or After?
Why?

Q2. When an Incident's Priority changes to Critical, send a notification to the Assignment Group. How would you implement this?

Q3. You need to prevent an Incident from being closed if the Resolution Notes are empty. Where would you implement this validation?

Q4. A field should automatically be populated before the record is inserted into the database. Which Business Rule type is appropriate?

Intermediate

Q5. Whenever the Assignment Group changes, you need to clear the Assigned To field. Write the Business Rule.

if (current.assignment_group.changes()) {
    current.assigned_to = '';
}

Why is Before Update preferable here?

Q6. You need to create a child task whenever a Change Request is created. Would you use Before or After?

Q7. A Business Rule is running twice unexpectedly. How would you troubleshoot it?

Q8. Your Business Rule is configured for Update + Priority changes, but it appears to execute when the record is created. What would you investigate?

Q9. You update a record from a Business Rule and accidentally trigger another Business Rule repeatedly. How would you prevent recursion?

2. Client Scripts

Q10.

When the Assignment Group changes on an Incident, automatically clear Assigned To.

Which Client Script type would you use?

Q11.

A field should become mandatory only when Category = Network.

Would you use:

Client Script?
UI Policy?
Data Policy?

Explain why.

Q12.

You need to populate a field when the form loads based on another field.

Write an onLoad Client Script.

Q13.

You need to validate a phone number before allowing the user to submit a catalog item.

Which Client Script type?

Q14.

A user enters a value in a field and you need to retrieve information from another table before populating another field.

How would you do this?

3. GlideAjax

Q15. ⭐ Important

On an Incident form, when the user selects Caller, you need to automatically retrieve the caller's department from sys_user.

Would you query sys_user directly from a Client Script?

Why/why not?

Explain how you would implement this using:

Client Script → GlideAjax → Script Include → Response

Q16.

Write a Script Include that receives a user sys_id and returns the user's department.

Q17.

Your GlideAjax call works in the backend but returns an empty value on the client.

What would you troubleshoot?

Q18.

Why should a Script Include called through GlideAjax generally be marked Client callable?

Q19.

What is the difference between:

getXML()

and

getXMLAnswer()

4. Script Includes

Q20.

You have the same logic being used in five Business Rules.

Would you duplicate the code?

How would you improve the design?

Q21.

Create a Script Include called IncidentUtils with a function:

getCriticalIncidents()

that returns the number of active Priority 1 incidents.

Q22.

A Script Include works when called from a Business Rule but not from a Client Script.

What could be wrong?

Q23.

What is the difference between:

Client-callable Script Include
Server-side Script Include

Q24.

You have a complex calculation that is required by multiple Flows and Business Rules. Where would you put the logic?

5. GlideRecord

Q25. ⭐ Very Important

Find all active incidents assigned to the Network team and print their numbers.

Write the script.

Q26.

Find all incidents where:

Priority = 1
State = Open

and update their Assignment Group.

Q27.

You need to find the manager of the Incident Caller.

How would you navigate:

Incident → Caller → Manager

using GlideRecord?

Q28.

What is the difference between:

get()

and

query()

Q29.

When would you use:

addQuery()

versus:

addEncodedQuery()

Q30.

What happens if you call:

gr.update();

inside a loop containing 10,000 records?

How would you optimize it?

Q31.

You need to delete old records from a custom table. How would you safely implement this?

6. GlideAggregate

Q32. ⭐

You need to find the number of Incidents assigned to each Assignment Group.

Would you use GlideRecord or GlideAggregate?

Write the approach.

Q33.

Find the number of active Incidents for each Priority.

Q34.

Find the average resolution time for Incidents.

Why would GlideAggregate be useful?

7. ACL / Security Scripting

Q35. ⭐ Important

Users should only be able to see Incidents where they are:

Caller
Assigned To
Member of Assignment Group

How would you implement this?

Q36.

A user can open a record directly using its sys_id, even though the record isn't visible in the list.

What security mechanism would you investigate?

Q37.

A user passes the table-level ACL but fails the field-level ACL.

Explain why.

Q38.

What is the difference between:

Table ACL
Field ACL
Row-level security

Q39.

You need to prevent users from modifying the salary field unless they have a specific role.

How would you implement it?

8. UI Policies

Q40.

If Incident Category = Hardware:

Make Configuration Item mandatory
Make it visible
Make it editable

Would you use a Client Script or UI Policy?

Why?

Q41.

What is the difference between:

UI Policy vs Client Script?

Q42.

A UI Policy works in Core UI but not in Workspace.

What would you investigate?

9. UI Actions

Q43.

You need a "Resolve Incident" button.

When clicked:

State → Resolved
Resolution Code → Solved
Resolution Notes → Mandatory

How would you implement this?

Q44.

A UI Action should only appear for users with the itil role.

How would you configure it?

Q45.

A UI Action should appear only when:

State = In Progress
AND
Assigned To = Current User

Write the condition.

Q46.

How would you hide a UI Action dynamically when a field changes?

10. GlideSystem (gs)

Q47.

What is the difference between:

gs.getUserID()gs.getUserName()gs.getUserDisplayName()

Q48.

How would you check whether the current user has a specific role?

gs.hasRole('itil')

Q49.

How would you retrieve a system property?

gs.getProperty('property.name')

Q50.

Why is using a system property better than hard-coding a sys_id?

11. GlideDateTime

Q51. ⭐

A task has a Due Date. If the Due Date is in the past, automatically move it to tomorrow.

How would you script this?

Q52.

Calculate the number of days between:

Opened
Closed

Q53.

You need to add 3 days to a GlideDateTime.

Which methods would you use?

Q54.

What is the difference between:

GlideDateTime
GlideDate
GlideTime

12. Catalog Client Scripts

Q55. ⭐

A catalog item has:

Requested For
Location
Department

When Requested For changes, automatically populate Location and Department.

How would you implement it?

Q56.

A catalog variable is inside an MRVS. You need to access its values from the Catalog Client Script.

How would you approach it?

Q57.

A variable should only be visible for users belonging to a particular group.

Would you use:

Catalog UI Policy
Catalog Client Script
User Criteria?

Explain.

Q58.

How would you prevent a catalog item from being submitted if a variable doesn't satisfy a condition?

13. Record Producer

Q59.

A Record Producer creates an Incident.

You want:

Category → Incident.category
Short Description → Incident.short_description
Requested For → Incident.caller_id

How would you map these?

Q60.

A user selects "Yes" on a Record Producer variable. Only then should an Incident be created.

How would you implement this?

14. Catalog / RITM / SCTASK

Q61. ⭐

A catalog item creates:

REQ
 └── RITM
      ├── SCTASK
      └── SCTASK

You need to automatically close the RITM when all SCTASKs are closed.

How would you implement it?

Q62.

A Flow creates an SCTASK but the Assignment Group is empty even though the catalog variable contains the group.

How would you troubleshoot?

Q63.

You need to retrieve catalog variables from an RITM using GlideRecord.

How would you do it?

15. Flow Designer Scripting

Q64.

An OOB Flow action cannot perform the required calculation.

What would you use?

Custom Action + Script step

Explain the design.

Q65.

Create a Flow Action that receives:

Incident Sys ID

and returns:

Caller Manager

Explain the inputs, Script step and outputs.

Q66.

A Flow is repeatedly triggering itself.

How would you identify and prevent the recursion?

16. Notifications / Email Scripts

How would you determine the recipient dynamically?

Q69.

You need to include catalog variables in an approval email.

How would you retrieve them?

Q70.

How would you use an Email Script to dynamically build HTML content?

17. Events

Q71.

A Business Rule should trigger a notification only when an Incident becomes Critical.

Would you directly send the notification from the Business Rule?

Or would you use:

gs.eventQueue()

Why?

Q72.

Explain:

gs.eventQueue(
    'incident.critical',
    current,
    current.number,
    current.priority
);

What are the parameters?

18. Scheduled Jobs

Q73. ⭐

Every night at 12 AM, find all tasks whose Due Date has passed and send a notification to the Assignment Group.

How would you implement it?

Q74.

You need to automatically close Incidents that have been resolved for more than 7 days.

Would you use:

Business Rule
Scheduled Script
Flow Designer

Why?

19. Transform Maps

Q75.

You receive a CSV containing:

Employee ID
Name
Department
Manager

You need to import it into sys_user.

How would you configure the Transform Map?

Q76.

The source contains duplicate users.

How would you prevent duplicate records?

Design the ServiceNow import process.

Explain:

External Source
      ↓
Import Set
      ↓
Transform Map
      ↓
Target Table

Q79.

Some records fail during transformation.

How would you troubleshoot them?

21. REST / Integration

Q80. ⭐

You need to send an Incident from ServiceNow to an external system whenever it is created.

How would you design the integration?

Q81.

An external application needs to create Incidents in ServiceNow.

Would you use:

Inbound REST API

or

Outbound REST Message?

Explain.

Q82.

The external API requires:

Authorization: Bearer <token>

How would you securely store and use the credentials?

Q83.

An outbound REST call returns HTTP 401.

How would you troubleshoot it?

22. Scripted REST API

Q84.

Create an API:

GET /api/company/incidents/{number}

which returns:

{
  "number": "INC0010001",
  "priority": "2",
  "state": "In Progress"}

How would you implement it?

Q85.

How would you secure a Scripted REST API?

23. GlideRecordSecure

Access to API blocked by cross-scope privilege

What does this mean?

Q89.

How do you handle cross-scope access properly?

25. Debugging

Q90. ⭐⭐⭐

A Business Rule is not executing.

What would you check?

A good troubleshooting sequence:

1. Table
2. Active
3. When
4. Insert/Update/Delete
5. Condition
6. Advanced condition/script
7. Order
8. Role/security
9. Other Business Rules
10. System logs

Q91.

A Client Script works in Core UI but not in Service Portal.

What would you investigate?

Q92.

A Client Script works in Service Portal but not Workspace.

What could be different?

Q93.

A GlideAjax call returns null.

How would you debug it?

26. Performance

Q94. ⭐

You find this script:

var gr = new GlideRecord('incident');gr.query();

while (gr.next()) {
    var user = new GlideRecord('sys_user');
    user.get(gr.caller_id);
}

There are 100,000 incidents.

What's wrong with this approach?

How would you improve it?

Q95.

Why should you avoid unnecessary GlideRecord queries inside loops?

Q96.

When would you use:

GlideAggregate

instead of GlideRecord?

Q97.

How would you optimize a query that takes several seconds?

27. Security + Scripting Scenario ⭐⭐⭐

Q98.

A user should only see Cases where:

Assigned To = Current User
OR
Current User is a member of Assignment Group

How would you implement this securely?

Would you use:

Client Script?
UI Policy?
ACL?
Business Rule?

Expected answer: ACL.

Client-side controls should not be relied upon for security.

28. Real Interview Scenario

Q99. ⭐⭐⭐

Your manager gives you this requirement:

"When an Incident is created, check whether the Caller is VIP. If the Caller is VIP, set Priority to 1, assign it to the VIP Support group, send an email to the manager, and create an investigation task."

Explain your complete technical design.

A strong answer would mention:

Before Business Rule
        ↓
Check Caller/VIP
        ↓
Set Priority + Assignment Group
        ↓
After Business Rule / Flow
        ↓
Create Task
        ↓
Event / Notification

And explain why you wouldn't put everything into one giant Business Rule.

29. Advanced Scenario

Q100. ⭐⭐⭐

A customer says:

"We have 50 Business Rules, 20 Flows and several Client Scripts modifying the same Incident fields. Sometimes the Assignment Group changes unexpectedly."

How would you troubleshoot?

You should discuss:

Transaction behavior
Business Rule order
Before vs After
Flow execution
Client Scripts
Data Policies
UI Policies
Audit history
System logs
Flow execution details
Debug Business Rules
Script Tracer
Avoiding conflicting automation
