I’ve compiled a list of 20 top Magento 2 interview questions and answers that have been asked in many companies before. Be sure to prep these and test your knowledge!

Magento 2 Interview Questions and Answers

Question 1. What is MVC Architecture?

MVC is the Model-View-Controller architecture that divides an application into 3 components- model, view and controller. The model takes care of the data and logic behind running an application. The view is pretty much everything you see on an application’s interface and it shows you whatever you want to see. The controller transmits or gives orders to the view and the model depending on the user’s request.

MVC is of two types- convention-based and configuration based. Magento uses a configuration based version, meaning if you have to get a module config file to work, everything will have to be specified to it.

Question 2: Which command is used to enable or disable a Magento 2 module? 

php bin/magento module:enable module_name

php bin/magento module:disable module_name

Question 3: What technology does Magento 2 use?

Magento uses MySQL for database and PHP as a web server language.

Magento 2 uses PHP 7.0.2 up to 7.0.10. PHP 7.0.5 is an exception since it has an issue that upsets the Magento code compiler. Versions 5.6x can also work. For MySQL, it uses version 5.6 or 5.7.

Question 4: What is EAV? 

The Entry, Attribute, Value model, also known as object-attribute-value or Open Schema, is a database or catalog management system that is used in Magento.

EAV was designed for databases where there might be a large number of attributes that define a certain entity, but not all of these attributes might apply to that entity. For example, let’s say that the entity is a product, defined by attributes like color, size, etc. The value would then be black, 12kgs, etc.

Using this model, only non-empty data values are stored. While this model facilitates efficient storage, it’s more complex than the Flat model because a developer has to run multiple queries to get complete information about a product or an entity.

Question 5. How can you write a custom module in Magento 2? 

Say you the model name is ‘hosting’. You have to define it in app/code folder

It should be: app/code/VendorName/moduleName.

For example: app/code/Webscoot/Hosting


  1. Create the folder of ‘hosting’ module
  2. Create etc/module.xml file
  3. Create etc/registration.php file
  4. Enable the module

Question 6: How can you improve the performance of Magento 2? 

  • Optimizing image size
  • MySQL Query Caching
  • Enable Magento caching
  • Enable Gzip caching
  • Disabling modules that aren’t in use
  • Write clean code
  • Use dedicated hosting services because it’s a resource-hungry platform.

Question 7: Which command is used to enable or disable a Magento 2 cache?

php bin/magento cache:enable

php bin/magento cache:disable

Question 8: How can you change the core Magento API settings?

  1. Go to the Admin menu.
  2. Choose System and then Configuration
  3. Select Magento Core API on the left side of the Configuration Panel
  4. Tap to expand the General Settings section
  5. Type the name of the Default Response Charset that you want to use
  6. Determine the Client Session Timeout in seconds
  7. Click the Save Configuration button when complete

Question 9: What is the difference between a cache:clean and cache:flush? 

Cache:clean deletes all the cache that has been enabled for Magento. Cache: flush on the other hand deletes all the cache storage whether it is from a third party or Magento cache.

Question 10: How many tables will be created when you make a new EAV model?

Six tables will be created. These include:

  • Module_datetime
  • Module
  •  module_decimal,
  • module_int
  • module_text
  • Module_varchar

Question 11: How can you reset Magento file & directory permissions?

You can reset them by following commands through the directory where Magento is installed.

find . –type f –exec chmod 644 {} ;

find . –type d –exec chmod 755 {} ;

chmod +x mage

Question 12:  Which File Stores The Vendor Path?

It’s vendor_path.php situated at app/etc/ folder.

Question 13: What are the different deploy modes in Magento 2?

The different deploy modes are:

  1. Default mode: Through this mode, you can deploy Magento applications on a single server. This mode is not optimized for production.
  2. Developer mode: used when you’re extending the functionality of your website or customizing it.
  3. Production: This mode is enabled when your Magento 2 website is in production.
  4. Maintenance: this mode prevents access to a Magento website when it is being updated or reconfigured

Question 14: What is the command to set up an upgrade in Magento 2?

php bin/magento setup:upgrade

Question 15: What is a factory class in Magento 2?

Factory classes are used to create, change, or get an entity without having to access the object manager since it is discouraged by Magento. These classes are created during code generation and do not need to be manually defined.

Question 16: What is dependency injection in Magento 2? 

Dependency injection is used in Magento 2 to replace the Mage class functionality that Magento 1 used.

It’s a pattern in which object 1 can declare its dependencies on object 2, and then object 1 doesn’t have to worry about procuring its own dependency requirements. Object 2 will do that based on desired behavior or configurations.
