Interview Masterclass & Capstone

Quick Introduction

You finished 119 focused PHP lessons — each about 8–12 minutes. This capstone ties them together with six course projects and a 700-question interview bank.

Projects: Login System, Blog CMS, REST API, Inventory Management, Employee Management, and E-Commerce Backend. Ship one project on GitHub with tests — that beats memorizing syntax lists.

Use the interview bank below: 5 Beginner, 3 Intermediate, and 2 Advanced questions per topic area, plus Staff-level prompts.

Business Problem

Teams hire developers who can build and explain a small API — not recite every PHP function. Your portfolio project proves you can apply variables through Laravel queues in one coherent app.

Pick one capstone, finish it in 1–2 weeks, and practice answering interview questions out loud using the bank on this page.

Core Concept

• Six projects span the full course — start with Login, grow into E-Commerce or REST API.
• Each earlier lesson maps to one file or class in those projects.
• 700 interview questions reinforce one concept at a time.
• Record yourself answering 3 questions per day for two weeks before interviews.
• Deploy a demo URL — even a free tier — so recruiters can click your work.

Syntax

Capstone checklist — copy this structure into your project README:

projects/
  login/          # Sessions, forms, auth
  blog/           # CRUD, Eloquent or PDO
  api/            # JSON, JWT, PHPUnit
  inventory/      # Transactions, repositories
  employees/      # OOP, roles, authorization
  ecommerce/      # Cart, checkout, queues

Keywords: README · docker-compose · PHPUnit · .env.example

Step-by-Step Example

Minimal REST API entry point combining lessons from Modules 4–6:

<?php
declare(strict_types=1);

require __DIR__ . '/vendor/autoload.php';

// Capstone: wire routing, auth middleware, JSON responses
header('Content-Type: application/json');
echo json_encode(['project' => 'TechLearningPRO API', 'status' => 'ready']);

Line by line

1. declare(strict_types=1) — same habit from Module 1.
2. require vendor/autoload.php — Composer from Module 3.
3. JSON header — REST APIs from Module 6.
4. Next: add JWT middleware, PDO repository, and PHPUnit tests.

{"project":"TechLearningPRO API","status":"ready"}

Real-World Example

Pick one capstone matching your job target: Login + Blog for web agencies, REST API + Inventory for backend roles, E-Commerce for Laravel shops. Finish it completely before starting the next.

Best Practices

• One Git commit per feature — login, posts, API routes.
• Green PHPUnit tests in CI before sharing your repo.
• README with setup steps and one architecture diagram.
• No secrets in Git — use .env.example only.
• Practice 3 interview questions daily from the bank below.

Common Mistakes

• Starting all six projects at once — finish one first.
• Skipping tests because the demo 'works on my machine'.
• Listing 119 lessons on a resume instead of one deployed project.
• Reading interview answers silently — always practice speaking.
• Ignoring earlier foundation lessons when debugging Laravel code.

Hands-on Exercise

Task: Deploy Capstone 1 (Login System) with registration, login, logout, and session regeneration.

Challenge: Add PHPUnit tests for valid login and invalid password paths.

<?php
declare(strict_types=1);
// TODO: Login capstone — see course project checklist

Summary

• 119 lessons complete — one concept per lesson, ~10 minutes each.
• Six course projects turn lessons into portfolio proof.
• 700 interview questions with model answers in the bank below.
• Ship one project before applying to PHP backend roles.
• Explain your code in interviews — don't memorize paragraphs.
• Keep learning: Laravel docs, PHP: The Right Way, and your own refactors.

Key Takeaways

• You finished a Laracasts-style PHP mastery path.
• You know how to learn one concept at a time.
• You have a project roadmap and interview bank.
• Next step: build Login or REST API this week.
• Schedule a mock interview when one capstone is deployed.
