If you’re preparing for a Salesforce Admin or Developer interview, you’ve probably noticed that most interviewers don’t just ask definitions—they want to know how Salesforce features are used in real business scenarios.
In this blog, we’ll cover 11 frequently asked Salesforce interview questions with simple explanations, practical examples, and interview tips. Whether you’re a fresher or have 1–3 years of experience, these questions will help you build confidence for your next interview.
1. What is a Lookup Relationship in Salesforce?
A Lookup Relationship is a loose connection between two Salesforce objects. It allows one object to reference another without making the parent record mandatory.
Unlike a Master-Detail Relationship, the child record can exist independently.
Example
Imagine you have two custom objects:
- Employee
- Parking Slot
Not every employee has a parking slot. In this case, creating a Lookup Relationship between Employee and Parking Slot is the right choice because the parking slot is optional.
Key Features
- Parent record is optional.
- Child record has its own owner.
- Sharing settings are independent.
- Parent deletion doesn’t necessarily delete child records.
- Roll-Up Summary fields are not supported.
2. How Does a Roll-Up Summary Field Work?
A Roll-Up Summary Field automatically calculates values from child records and displays the result on the parent record.
It only works with Master-Detail Relationships.
Salesforce supports four calculations:
- Count
- Sum
- Minimum
- Maximum
Example
Suppose an Account has three Opportunities:
- ₹50,000
- ₹30,000
- ₹20,000
A Roll-Up Summary Field with the SUM function will automatically display:
Total Opportunity Amount = ₹100,000
No Apex or Flow is required.
3. What is a Record Type?
A Record Type allows different business processes, page layouts, and picklist values for the same object.
This is useful when multiple teams use the same object differently.
Example
Consider the Case object.
The Customer Support team handles:
- Technical Issues
- Product Bugs
The Finance team handles:
- Refund Requests
- Payment Issues
Instead of creating separate objects, Salesforce uses different Record Types with different page layouts and picklist values.
Benefits
- Multiple business processes
- Different page layouts
- Customized picklist values
- Better user experience
4. What are Dynamic Forms?
Dynamic Forms allow Salesforce administrators to show or hide fields and sections based on conditions.
Instead of displaying every field to every user, only relevant information is shown.
Example
Suppose a Lead’s Status becomes Qualified.
Only then should users see:
- Budget
- Timeline
- Decision Maker
If the Lead is still “New,” these fields remain hidden.
This creates cleaner pages and improves productivity.
Benefits
- Less scrolling
- Faster page loading
- Personalized experience
- Easier maintenance
5. How Do You Create a Many-to-Many Relationship?
Salesforce doesn’t directly support many-to-many relationships.
Instead, it uses a Junction Object.
A Junction Object contains two Master-Detail relationships.
Example
A Student can enroll in many Courses.
A Course can have many Students.
Create an object called Enrollment.
Relationships:
- Student → Enrollment
- Course → Enrollment
Now one student can join multiple courses, and one course can have many students.
This is the standard Salesforce approach for many-to-many relationships.
6. Feed Tracking vs Field History Tracking
Although both track record changes, their purpose is different.
Feed Tracking
Feed Tracking posts important field updates in Chatter.
Example
If an Opportunity Stage changes from Qualification to Closed Won, everyone following that record can see the update in Chatter.
It is mainly used for collaboration.
Field History Tracking
Field History Tracking stores old and new values for audit purposes.
Example
If an employee’s salary changes from ₹50,000 to ₹60,000, Salesforce stores:
- Old Value
- New Value
- Modified By
- Date and Time
This is useful for compliance and reporting.
7. What is a Compact Layout?
A Compact Layout controls the important fields displayed in the Highlights Panel at the top of a Lightning record page.
It also appears in mobile apps and lookup results.
Example
For an Account, the Compact Layout may display:
- Account Name
- Phone
- Industry
- Rating
Users can quickly view important details without opening every section of the record.
8. What are Validation Rules?
Validation Rules prevent users from saving incorrect or incomplete data.
If a condition evaluates to TRUE, Salesforce displays an error message.
Example
A company wants to ensure Opportunity Amount is never negative.
Validation Rule:
Amount < 0Error Message:
“Amount cannot be negative.”
Another example:
If a Lead is marked as Qualified, the Email field becomes mandatory.
Validation Rule:
AND(
ISPICKVAL(Status,"Qualified"),
ISBLANK(Email)
)This ensures data quality across the organization.
9. How Many Ways Can You Make a Field Required?
There are four common methods.
1. Required Field
While creating the field, select “Required.”
This makes the field mandatory everywhere.
2. Page Layout Required
Makes the field mandatory only in the user interface.
API integrations and Data Loader can still bypass it.
3. Validation Rule
Used when the field should be required only under certain conditions.
Example
If Opportunity Stage is Closed Won, then Contract Number must be entered.
4. Apex or Flow
Used when business logic is more complex.
Example
Prevent record creation until Manager Approval is completed.
10. What are Global Picklist Value Sets?
A Global Picklist Value Set allows multiple fields to share the same list of values.
Instead of creating separate picklists, Salesforce lets administrators maintain values in one place.
Example
Suppose multiple objects need a Country field.
Values:
- India
- USA
- Canada
- Australia
Instead of creating separate picklists for every object, create one Global Picklist Value Set.
Whenever a country is added or removed, all fields update automatically.
Benefits
- Easy maintenance
- Consistent data
- Reusable across objects
- Saves administration time
11. Data Loader vs Data Import Wizard
Both tools help import Salesforce data, but they serve different purposes.
Data Loader
Data Loader is a desktop application designed for large-scale data operations.
It supports:
- Insert
- Update
- Upsert
- Delete
- Export
- Export All
It works with CSV files and can process millions of records.
Example
A company wants to migrate 2 lakh customer records into Salesforce.
Data Loader is the best choice.
Data Import Wizard
Data Import Wizard is a browser-based tool designed for smaller data imports.
It is simple to use and requires no installation.
Best suited for:
- Leads
- Accounts
- Contacts
- Campaign Members
- Custom Objects
Example
A sales executive needs to upload 2,000 new Leads.
The Data Import Wizard is quick and user-friendly.
Data Loader vs Data Import Wizard
| Feature | Data Loader | Data Import Wizard |
|---|---|---|
| Installation | Desktop Application | Browser-Based |
| Record Limit | Millions | Up to 50,000 records per import |
| Operations | Insert, Update, Upsert, Delete, Export | Import and Update (supported objects) |
| Objects Supported | All Standard and Custom Objects | Selected Standard and Custom Objects |
| Best For | Large Data Migration | Small Business Imports |
| Ease of Use | Moderate | Beginner Friendly |
