15 Laravel Developer Interview Questions That Actually Reveal Skill

Most Laravel interview guides focus on trivia. Real interviews should reveal how a developer thinks, ships, debugs, and communicates.

These questions are designed to uncover real production experience.


## 1. Walk me through the last Laravel app you built from scratch.

**Listen for:** Specific architecture decisions, tradeoffs, and production lessons.

**Weak:** “It had auth, CRUD, and an admin panel.”

**Strong:** “We built a multi-tenant invoicing platform. I used shared database tenancy with `tenant_id` scoping because it simplified infrastructure at our scale. We later fixed a tenant-scope bug caught during testing.”


## 2. How would you design a SaaS app with isolated customer data?

**Listen for:** Understanding of multi-tenancy.

A strong developer explains both shared database and separate database approaches, including tradeoffs around scalability, cost, and compliance.


## 3. How do you debug Laravel performance problems?

**Listen for:** Real debugging experience.

Strong answers mention:

* Laravel Debugbar or Telescope
* N+1 query detection
* Eager loading with `with()`
* Indexing
* Queueing expensive work
* Caching repeated queries


## 4. What's the difference between `with()` and `load()`?

**Listen for:** Practical Eloquent knowledge.

`with()` eager loads during the query.
`load()` eager loads relationships after models are retrieved.

A strong developer knows when each avoids N+1 issues.


## 5. When would you use global scopes vs local scopes?

**Listen for:** Judgment.

Local scopes work well for reusable filters like `published()`.
Global scopes are best for rules that must always apply, such as tenant isolation or soft deletes.


## 6. What security mistakes have you seen in Laravel apps?

**Strong answers mention:**

* Mass assignment issues
* Unsafe raw SQL queries
* Missing CSRF protection
* Exposed `.env` files
* Unsafe file uploads
* Exposing predictable IDs instead of UUIDs


## 7. Policies vs Gates — when do you use each?

**Strong answer:**

* Gates for simple app-level checks
* Policies for model-specific authorization

Good developers usually prefer policies because they're organized, testable, and scale better.


## 8. How would you send an order confirmation email without slowing checkout?

**Listen for:** Queue knowledge.

Strong answers mention queued jobs, Redis queues, Horizon monitoring, retries, and failed job handling.

## 9. What happens when a queued job fails?

**Strong answers mention:**

* `failed_jobs` table
* Retry strategies
* Exponential backoff
* Horizon alerts
* `failed()` handlers for critical jobs


## 10. How do you test a controller that sends email and writes to the database?

**Listen for:** Practical testing workflow.

Strong answers mention:

* `Mail::fake()`
* Feature tests
* `assertDatabaseHas()`
* Mail assertions
* Validation failure tests


## 11. Unit tests vs feature tests in Laravel?

**Strong answer:**
Feature tests verify the full request lifecycle and provide the most confidence.

Unit tests are best for isolated business logic like pricing engines or parsers.


## 12. How do you refactor a messy Laravel codebase?

**Listen for:** Incremental thinking.

Strong developers avoid rewrites. They add tests around areas being changed, refactor gradually, and reduce risk step by step.


## 13. Are repositories worth using in Laravel?

**Listen for:** Nuanced thinking.

Strong developers avoid dogma. Repositories can help large systems with complex query logic, but often add unnecessary abstraction in small projects.


## 14. Tell me about a technical disagreement you handled.

**Listen for:** Communication skills.

The best developers can disagree professionally, explain tradeoffs clearly, and still support the final decision.


## 15. How do you stay current with Laravel?

**Listen for:** Genuine ecosystem involvement.

Strong answers mention things like Laravel News, Laracasts, Laracon talks, Pest, Pint, Horizon, or recent Laravel features they've adopted.



## Paid Trial Tasks Matter More Than Interviews

The best hiring signal is usually a paid trial task.

Give candidates a realistic feature, bug fix, or code review exercise. Their communication, questions, code quality, and delivery process reveal far more than trivia questions.


If you'd rather skip the screening process entirely, Devlyn provides pre-vetted senior Laravel developers from India who have already passed technical assessments.

That means your interviews can focus on culture fit and project alignment instead of proving basic Laravel competence.
