43 Interview Questions Based on Experience Levels and Their Answers

For non-technical positions

1. Magento 2 is a popular platform for e-commerce. Can you explain in simple terms what it is and why a company might use it?

Magento 2 is like a powerful engine that drives an online store. It’s the software that handles everything from displaying products and taking orders to managing customer information and processing payments. Companies use it because it’s very flexible and scalable, meaning it can grow with their business and handle complex needs, like large catalogs of products, different pricing for different customers, and integration with other systems. Think of it as the behind-the-scenes technology that makes a sophisticated online shopping experience possible.

2. If a customer is having trouble with their online order, like they can’t find a product or their discount code isn’t working, how might Magento 2 be involved?

Magento 2 is the system that controls how products are displayed, how discounts are applied, and how the entire checkout process works. So, if a customer can’t find a product, it might be an issue with how the product is categorized or displayed within Magento 2. If a discount code isn’t working, the problem could lie in how the discount rules are set up within the platform. Our team would use Magento 2’s admin panel to investigate and resolve these issues.

3. How does Magento 2 help us with marketing and sales efforts?

Magento 2 offers several tools that are helpful for marketing and sales. For example, it allows us to create targeted promotions, manage email marketing campaigns, and track customer behavior on the website. It also provides detailed reports on sales, popular products, and customer demographics, which we can use to make data-driven decisions about our marketing strategies and product offerings. It’s a central hub for managing our online sales and marketing activities.

4. If we decide to add a new feature to the website, like a customer loyalty program, how would Magento 2 be involved?

Adding a new feature often involves working with developers who are familiar with Magento 2. They would use their technical expertise to either configure existing features within Magento 2 or build custom extensions to add the new functionality. Our team would work with the developers to define the requirements for the loyalty program and ensure it integrates seamlessly with the existing Magento 2 system.

5. If you are responsible for updating product information on the website. Will you need to learn coding to use Magento 2?

Not necessarily. While Magento 2 is a complex platform, many day-to-day tasks, like updating product information, can be done through a user-friendly interface called the admin panel. You’ll likely receive training on how to use this interface to manage product listings, pricing, images, and other details. You won’t need to write code for these basic updates.
