10 beginner Salesforce developer interview questions and answers 

Check out these beginner interview questions and answers to better understand the candidate’s knowledge, skills, and experience with CRM. 

1. What is meant by an object in Salesforce?

The candidate should know that objects in Salesforce are database tables that store important information about an organization. Junior candidates could give a basic definition before explaining how objects help developers track and manage data. 

Candidates who list the two object types should also get a bonus point: 

• Standard object: Salesforce provides the objects, such as contacts, accounts, cases, campaigns, leads, contracts, dashboards, and products. 

• Custom object: Users make modifications to Salesforce by changing page layouts, custom user interface tabs, custom fields, and relationships to other objects. 

Remember that candidates who provide detailed examples of objects most likely have experience with using Salesforce in previous jobs. 

2. Give me some benefits of using Salesforce CRM.

Salesforce CRM offers users many benefits, and candidates should list a few. For example, they might mention that customer relationship platforms focus more on solving customer issues and attracting different audiences to the company. 

Here are a few other benefits the candidate might mention: 

• Improved customer engagement 

• Enhanced communication 

• A deeper understanding of customer needs

• Automated rule-based tasks 

• Stronger analytics and dashboards 

• Reduction in cycle time and cost 

• Better efficiency of teams 

• Easier to sync data from various applications

Customer experience (CX) drives business profits, so candidates must understand how Salesforce plays a role in customer experience and marketing automation. 

3. What are the features of Salesforce?

A candidate should have extensive knowledge of Salesforce’s features. Since they want to work in the cloud computing industry, they must understand how this CRM platform functions. The candidate doesn’t need to list every feature, but they can describe specific components that contribute to CX. 

Below are the top features of Salesforce:

Contact and account management: This feature provides access to customer data and interactions. Salesforce can use customer-based information to improve engagement and better understand opinions toward specific products. 

Data management: Using data cleaning leads to updated accounts and contacts that help drive marketing processes. With AI constantly evolving, it’s important to gather more reliable data in Salesforce. 

Opportunity management: You can view how customers behave when navigating products, websites, or social media pages. This feature helps companies to make the customer experience more personal and organized.

Lead management: This CRM tool shows the up-to-date activity of specific accounts and contacts. Many companies rely on lead management to stay in the loop and gain more revenue from sales. 

Candidates might also mention the following features: 

• Dashboard and reports

• Salesforce mobile application to join meetings and receive updates

• Sales forecasting

• Customer support

• Third-party integrations with apps like G Suite, MailChimp, and Quickbooks

• Workflow and approvals

• Sync files with the company

4. What is meant by an app in Salesforce?

Applicants can show off their Salesforce skills by explaining the meaning of an app in this program. For example, an app is a group of functional tabs that help an application run smoothly. Most of the time, these apps also contain a name and logo, depending on the company’s requirements. 

5. Apart from CRM, what other products does Salesforce have?

Salesforce has an extensive portfolio containing a range of unique products. Most of these products integrate and provide a rewarding experience for everyone. Before explaining their functions candidates may name a few products like Marketing Cloud, Slack, or Commerce Cloud. 

6. What is Apex?

Apex is a programming language developers use to execute flow and transactions. This feature also gives users access to client-server interfaces when creating SaaS applications for third-party systems. 

Candidates who have experience with Salesforce should know about Apex. It is a popular application programming interface (API) that stores data and takes features from Java models. 

Send each candidate a Java Data Structures test to better understand their programming skills and API knowledge. 

7. What is an audit trail?

The audit trail is a unique feature that tracks changes made by developers and administrators in the organization. It’s a simple element that candidates should be aware of if they want to build apps and keep up to date with recent developments. 

Strong candidates will include the following points in their response:

• Who made the change 

• The date and time of specific changes 

• What the change was 

8. Define SOQL and how you would use it. 

SOQL stands for Salesforce Object Query Language. It is a programming language that allows developers to create query strings (portions of a URL that track where customers come from).

In Salesforce, query languages are an advanced concept because they help developers and administrators retrieve data from objects. 

9. What is the Lightning platform? 

The Lightning platform is a framework for app development in Salesforce. This cloud computing software uses tools and technologies to enhance an app’s performance while simplifying business processes for less experienced programmers. 

Some key features of Lightning include:

• Graphical user interface (GUI) for optimizing speed 

• A no-code development builder that supports app customization 

• Tools and extensions that focus on reusable components

• Design system for style guides and CX 

• Integration tool that takes data from external resources 

10. Name some of the Salesforce subsidiaries.

Salesforce has several subsidiaries that encourage more brand recognition and offer increased tax benefits. Candidates should know at least two or three of these holding companies if they have worked with Salesforce systems before. However, beginners might not have this knowledge, but that doesn’t mean they can’t learn more about subsidiary companies.

These are the major Salesforce subsidiaries: 

• Tableau 

• SalesforceIQ

• Pardot

• Mulesoft

• Heroku

• Demandware Inc

8 intermediate Salesforce developer interview questions and answers

Refer to these interview questions and answers when comparing candidates’ responses after the Salesforce developer interview. 

1. Explain the difference between Salesforce Object Query Language and Salesforce Object Search Language.

Salesforce Object Query Language (SOQL) and Salesforce Object Search Language (SOSL) are primary tools developers use to retrieve important information, but they have one difference. SOQL means you can only search one object at a time, while the Salesforce Object Search Language (SOSL) allows you to search an entire organization and database. 

2. What are triggers in Salesforce?

Triggers are pieces of Apex code that developers execute before or after they update a business record. Users separate these triggers into two categories, depending on how Salesforce developers manage them in cloud computing:

Before triggers: Developers can update and change the values of a record and save them to the company database. 

After triggers: You can access field values of records in the current database and change other stored records when necessary. 

Candidates who mention both of these triggers may be more advanced and knowledgeable about the Apex system. You can also send each candidate an Understanding Instructions test to determine their ability to understand Apex code and execute it in a workplace setting. 

3. Tell me about the Force.com platform.

The Force.com platform is a Platform as a Service (PaaS) product that simplifies the deployment of cloud websites and applications. Salesforce developers can create apps through an integrated development environment and release them on Force.com’s servers. 

Check if your candidates can provide some benefits of this PaaS, which might include:

• Fast data access

• More active development

• Fewer business expenses

• Protected information

4. List some email templates available in the Salesforce platform.

Candidates should provide examples of email templates that help developers send quick emails to others in the organization. These are simple tools, but most professional Salesforce developers must know how to use them properly. 

Some email templates include: 

• Text: Any user can change or modify this template. 

• HTML with letterhead: Administrators and users with edit permission can create this email based on the top heading. 

• Custom HTML: Administrators and users with edit permission can create this email without a letterhead. However, this template requires knowledge of HTML, as the user needs to insert HTML code into the email. 

• Visualforce: Only administrators and Salesforce developers can create this template, as they have to be able to merge data from a range of records.

An HTML5 test will help you determine whether the candidates can:

• Arrange formatting tags

• Build a website application

• Structure HTML concepts like emails 

5. How do you create a many-to-many relationship?

A many-to-many relationship happens when multiple records relate to more than one record in another table. This data model represents the relationships and patterns between customers and products. 

The candidate should know how to connect objects and link them with records. They can do this by adding a third table as a go-between. This table creates a relationship (many-to-many) with all objects. 

6. Why do we need to write test classes?

Salesforce developers need to write test classes to use error-free code. Documenting test classes ensures all code works properly without the risk of corrupted records or company data. Even if candidates don’t have experience with test classes, they should still know what they are and why they are essential for developers. 

7. What is a static resource in Salesforce?

Static resources are digital resources that developers have not assigned to a dedicated path network in a Salesforce platform. Developers can use a static resource to upload content to a Visualforce page, such as images, style sheets, and JavaScript. The ideal candidate may also know that the maximum size of a static resource is 250 MB.

Consider using a  JavaScript test to see how well candidates can upload code or use static resources in a programming environment. 

8. What is a batch job in Salesforce?

A batch job is a method that Salesforce developers use to manage large transactions by splitting a single task into manageable chunks. This method is ideal for facilitating data processing in the database. In batch apex, developers will also separate records when doing field updates for an organization.

5 advanced Salesforce developer interview questions and answers

Use these advanced Salesforce developer interview questions and answers when reviewing your candidates’ responses after the interview.

1. Have you ever dealt with data loss? How did you do it?

This question can test whether the candidate has enough knowledge and experience with Salesforce data.  They might show their expertise, explain what data loss is, and describe how they overcame it using specific tools like data export and sandbox. 

In terms of Salesforce, data loss can refer to accidental deletion, hardware corruption, cyber-attacks, or poor software services. These potential reasons may erase important information associated with the organization. According to recent studies, the pressure of technology puts any business at risk of data corruption. 

However, developers can do simple things like checking the recycling bin, exporting data from weekly records, or using a Salesforce data recovery service to restore essential records. 

Send candidates a Big 5 (OCEAN) personality test to learn more about their openness, conscientiousness, extroversion, agreeableness, and emotional stability when it comes to solving problems. You could also use a Problem-Solving test that focuses on how candidates approach complex situations. 

2. What are the considerations for a skinny table?

Candidates should know what skinny tables are and how to create one. This knowledge shows their ability to add soft-deleted records to a custom table. 

Below is some useful information regarding skinny tables: 

3. How do you display error messages on the Visualforce page?

A Salesforce developer can use the ApexPages software to write error codes. When asking candidates this question, you may get them to write an example message. This activity is great for testing their knowledge and critical thinking skills. 

Examples: 

Visualforce page: apex:pageMessages</apex:pageMessages>

Apex class: ApexPages.addMessage(new ApexPages.Message(ApexPages.severity.Error, ‘Error Message’));

Consider sending each candidate a Critical Thinking skills test to evaluate their analytical skills and ability to interpret sequences and arrangements. 

4. Where can we use Lightning components?

There is a range of ways Salesforce developers can use Lightning components. It depends on the user interface (UI) framework and programming language. You need an efficient UI to make responsive applications on the Lightning platform. Candidates should give a few examples of how they might use Lightning components in this role. 

A few ways to use these components include: 

• Lightning experience

• Salesforce1 app 

• Lightning pages and apps

• Visualforce pages

• Standalone Salesforce apps

• Community builders 

5.  Explain what chatter API and connect API mean in Salesforce. 

Chatter API (also known as Rest API) is a programming interface that uses several computer systems to transfer information. This social networking application helps developers and administrators share data. Salesforce Chatter also has a mobile feed you can use to share ideas. 

On the other hand, Connect API is a secure management tool that helps developers create, manage, and secure an application programming interface. Connect focuses more on displaying chatter feeds on mobile apps as well. 

The REST API test is suitable for candidates who want to build and maintain efficient APIs. You can determine which candidates can overcome errors and manage response codes in Salesforce. This assessment also covers topics such as data security and server-related matters.
