Apex based Salesforce Interview Questions with Answers
17. What is Batch Apex?
Batch Apex is used for many records, data is divided into small batches of records, and then these batches will be executed. Batch class is generally used to process bulk records together so that we have a greater governor limit when compared to the synchronous code.
18. Name the methods to be implemented in Batch Apex?
The methods to be implemented in Batch Apex are as follows:
- Start method (used to collect chunks of data for processing)
- Execute method (used to perform operations on the collected data)
- Finish method (used for sending emails)
19. Can we call a batch class from a batch class? If yes, how?
Yes, we can call another batch class from the Finish method.
20. Can we make callouts from Batch Apex? If yes, how?
Yes, we must implement using the interface Database.AllowCallouts.
21. What are the limitations for Batch Apex?
- Batch Apex jobs run slower when we use relationship subqueries in QueryLocator in the Start Method.
- It is not possible to call future methods from the Batch Class.
- Batch Apex creates one additional AsyncApexJob record for every 10,000 records of BatchApexWorker type, we must keep this in mind when we are querying the records.
- Use Starttest and Stoptest methods around the Execute method.
22. What is the schedule Apex?
Schedule apex is used to execute an Apex code snippet at a specific period of time. To schedule an apex class, we need to implement a Schedulable interface.
23. How can we schedule a Batch Apex?
We can schedule a Batch Apex in two ways from user interface & programmatically using System.scheduleBatch method.
24. What is System.schedule()?
System.schedule() method is used to execute the schedulable interface.
System.schedule() method takes 3 parameters:
- Name of the job
- An expression that represents the time and date.
- The object of the class to be executed.
25. What is the return type of System.schedule()?
System.schedule() method returns Job ID.
26. Does Apex Scheduler run in system mode?
Yes, Apex Scheduler runs in system mode.
27. How to Lock the records which are queried through Apex?
Using the FOR UPDATE keyword, we can lock the rows fetched by SOQL query.
28. How to avoid nested iterations?
We can use map collections to avoid writing loop inside loop. This will decrease the execution time.
29. What is the twin field concept?
When Custom fields of two different Objects are editable and have the same API name and Data type, we call these fields as “twin fields”. Values pass from object A to object B when object B record is created.
30. What is a co-terminated subscription in Salesforce?
Co-terming in quotes means termination of contracts. Fields such as Contract Co-Termination(SBQQ__ContractCoTermination__c) determine how Salesforce CPQ co-terminates contracts for this customer.

31. What is block pricing in Salesforce CPQ?
We can price a product based on quantity ranges. This is called block pricing.
32. What are bounded and unbounded queries in Salesforce?
- Bounded Queries – Where we have a well-defined set of fields, for example, all standard fields.
- Unbounded Queries – Where we have a set of fields that are not predetermined, for example, all fields or all custom fields.
33. What is asynchronous Apex? How many types of asynchronous Apex are there in Salesforce?
Asynchronous Apex is used to run processes in a separate thread when the resources are available for execution. There are four types of asynchronous operations available in Salesforce.
- Future Methods
- Batch Apex
- Queueable
- Scheduled Apex
34. Can we call a future method from another future method?
No, we cannot call a future method from another future method.
35. What are the best practices of writing Apex?
Following are the list of best practices of writing Apex:
- Always bulkify the code for future reference.
- Avoid SOQL queries inside the loop.
- Don’t use hardcoded values, and try to use dynamic values.
- Single trigger per single object.
- Consider the order of execution while writing any code.
36. How many types of relationships are available in Salesforce?
There are different relationships available in Salesforce:
- Master-Detail
- Lookup Relationship
- Self- Relationship
- External lookup relationship

We can add up to a maximum of 10 fields in a compact layout.
39. How to call a class in process builder?
If we must call a class in a process builder, we have to declare that class with the annotation of @invocablemethod.
40. What are before and after triggers?
The triggers which run before the save of a record, we call them as before triggers and the triggers which run after saving the record are after triggers.
41. Can we bypass a validation rule?
Yes, we can bypass a validation rule to run for the records which are created newly instead of running for all the records.
42. What is the use of the test setup method?
We can use the test setup method to create some data for test class and we can use that data in any other method in test class.
43. What is test.starttest and test.stoptest?
Suppose if we want to run one method as asynchronous / have some long complex operations (which has multiple SOQL queries) then we will use test.starttest and test.stoptest to consider it as separate thread of execution to overcome the too many SOQL queries limit exception.
44. What is a dependent picklist?
If we want to control a picklist value based on selection of value in another picklist then we will use a dependent picklist.
45. What are the methods in batch Apex?
There are three methods in batch Apex. They are:
- Start
- Execute
- Finish
46. Can we write a batch Apex by excluding any one of the methods?

There are basically two types of sharing rules in Salesforce:
- Owner- based sharing rules.
- Criteria- based sharing rules.
48. What is the use of a change set, and what is the max size of a change set?

Advanced Salesforce Interview Questions with Answers
51. What is the difference between a custom controller and standard controller?
The standard controller is generated by Salesforce for all the objects. Whereas, a custom controller is defined by us with our custom logic using Apex.
52. What is the benefit of using custom metadata and custom labels?
By using custom metadata/ Custom Label, we can get the data stored in Custom metadata/ custom labels without writing any SOQL queries.
53. Can we use records of multiple objects in one UPSERT command?
No, we cannot.
54. What is multi-tenant architecture?
Whenever any platform shares resources with all customers, then this system is called multi-tenant architecture (MTA). Similar is the case with Salesforce Application.
55. What are the differences between SOQL and SOSL?
SOQL (Salesforce Object Query Language):
- Using SOQL the user can make queries only on 1 object at a time.
- The user can query fields of any data type.
- The user can perform DML operations on query results.
- Return type: List
SOSL (Salesforce object Search Language):
- Using SOSL the user can make queries on many objects at an instance.
- We can query only on fields having type Name, phone, or Email.
- The user cannot perform DML operations on the search results.
- Return type: List of list.
56. Why do we need 2 query languages in Salesforce?
SOQL is for “fetching” records based on some parameters/conditions.
Example:
get the records from the database where the country of customer = India
Here, Query has some conditions. We will not do any random table searches. Everything has to be clearly mentioned.
SOSL = for “searching” some information in the database.
Example:
If the user would like to write a code so that he/she can see records where the word “Andrew” is used in the database. (Has no connection to any criteria like the above)
Search queries will have a “text” to search.
57. What are the variations in Count ()?
Count()
Count(Field’s API Name)
Count_Distinct(Field’s API Name)
(THESE ARE ALSO CALLED AS AGGREGATE FUNCTIONS)
Count will display the result of all records while Count Distinct will display only distinct count. For example, a table has 5 records namely a,a,b,b,c then Count results in 5 while Count distinct results in 3.
58. What are Wild Characters / LIKE keywords and when are they used?
When we want to make a query on something which is not an exact value, like Name: “Andrew”, Tech : “Salesforce” etc., (these are exact values), and we only know the approx. format of it, in this case we can use the Wild characters.
This helps to find those records matching the xyz pattern.
Example:
We do not know that it’s “Salesforce” but we know it starts with “Sal” or ends with “ce”.
59. What are aggregate functions in SF?
MIN, MAX, COUNT, SUM, and AVG
Examples:
SELECT MAX(Andy__Experience__c) FROM
Object __Name __c
60. Which function do we use to load data from .CSV and do testing?
Test.loadData()
61. What are the types of Approval Processes?
- Jump Start Wizard
- Standard Setup wizard
62. Out of all Approval Processes which one will you select and why?
Jump Start wizard:
- This type is used to create a very simple Approval Process
- This has very few steps
- We get fewer options to configure
- Not regularly used in real-time scenarios
Standard Setup wizard:
- This is a commonly used Approval process
- This has all features needed in the Approval Process
- This has more steps compared to Jump Start Wizard
- This will give us the right to configure the Approval Process in a detailed manner
- This is used when there is a complex business scenario/requirement
63. What is the Outbound Message feature?
This is a feature by which we can connect from the Salesforce platform to other external platforms “without any code”. This works similar to Workflow rule action, i.e. it will work when any record is created/updated.
64. How can we check whether OBM is triggered or not?
We can check the status of the OBM from “Outbound Messages” in the setup.
65. What are Time Dependent actions in Salesforce?
There are some cases where we do not want to execute a particular action instantly, rather, we want the particular action to happen after viz. 1 hr, 10 hrs, 10 days, etc., In such a scenario we can achieve the solution by time-dependent actions in salesforce.
66. To what all entities can we create a Task?
User and Role.
67. Can we have a merge field in the Task email body?
No.
68. What are the types of email templates we can create in Salesforce?
- Text
- HTML (using Letterhead)
- Custom (without using Letterhead)
- Visualforce
69. Difference between Public Group and Queue?
Queue:
- It is a group of users
- We use this for transferring the ownership of records
- We use Queue not to share the record with group of users, but to transfer the “responsibility” of that business entity (record) with them. (Ex: Object Deal__c)
- We mostly use this concept with approval process as well as Lead object
- In Lead object, we use this for load balancing, means, giving ownership of a lead record to a group of users.
Public Group:
- This is a group of people we can add from any department (it’s not necessary that members of Public Group are from same department)
- Helps to share records with large number of users in one click
- Useful in Manual sharing / Sharing rule.
- Once created, we can use Public Group for any object.
70. What is Sharing Rule and how many types of Sharing rules we have in Salesforce?
To share the records, based on some conditions, we use Sharing Rules (dynamic sharing). This is also called as Selective Sharing.
Types of Sharing Rules:
- Owner based Sharing Rule
- Criteria Based Sharing Rule
- Guest user sharing (not commonly used)
