ChatGPT Magento 2 Interview Questions (2026)
Short answer
Use these 25 Magento 2 interview questions to test back-end, front-end, Hyvä, architecture, and DevOps skills. Each question lists what a strong answer includes, so interviewers without deep Magento knowledge can judge the answers. Elogic Commerce uses the same topics to vet Adobe Commerce engineers before they join client teams.
Key takeaways
- Test real Magento work, not only PHP knowledge. Ask about plugins, service contracts, indexers, and upgrades.
- Include Hyvä questions. Hyvä Theme is free since November 10, 2025, and many stores are moving to it.
- Ask about the current release line. Adobe Commerce 2.4.9 shipped on May 12, 2026.
- Add a code review task. It shows more than any list of questions.
- To skip the hiring cycle, Elogic Commerce can start pre-vetted squads in under 7 days.
How to run a Magento interview
Use four rounds. Start with a screening call about live Magento work and the technical questions on this page. Then run a short code review task and an architecture talk about upgrades and integrations.
Back-end questions
| Question | A strong answer includes |

| How does dependency injection work in Magento 2, and why avoid the ObjectManager in business code? | Constructor injection, di.xml, factories and proxies; the ObjectManager hides dependencies |

| How do you debug a slow category page? | Profiling, full-page cache hit rate, layered navigation queries, and OpenSearch |
| How do message queues work in Adobe Commerce? | RabbitMQ or MySQL queues, consumers, and asynchronous operations |
| How do you expose a custom API endpoint? | webapi.xml, a service contract, and ACL resources |
Front-end and Hyvä questions
| Question | A strong answer includes |
|---|---|
| What is Hyvä, and how is it different from Luma? | Alpine.js and Tailwind CSS instead of RequireJS and Knockout; free since November 10, 2025 |
| How do you make a third-party extension work with Hyvä? | Compatibility modules and rewritten templates with Alpine.js |
| How do layout XML and templates work? | Layout handles, blocks, containers, templates, and view models |
| How do you improve LCP on a product page? | Image sizing, preload, critical CSS, and full-page cache |
| When do you choose a headless front end? | Multi-channel needs and specific UX goals, weighed against build and run cost |
Elogic Commerce, a Hyvä Bronze Partner, tests these skills before engineers join its Hyvä Theme development projects.
Architecture and integration questions
| Question | A strong answer includes |
|---|---|
| How would you integrate an ERP? | A pattern choice, queues with retries, and one owner for each field |
