What I learned from getting several offers from FAANG+ Frontend Interviews in 2024

Overview

In 2024, a frontend engineer undertook an intensive six-month preparation journey targeting FAANG+ companies, ultimately securing multiple offers. This experience provides valuable insights into the modern frontend interview landscape, highlighting the distinct focus on domain-specific knowledge rather than traditional algorithm-heavy questioning.

The candidate discovered early that LeetCode-style problems, while useful, represent only a fraction of what frontend interviews assess. Instead, companies emphasise practical JavaScript coding, framework proficiency, system design thinking, and behavioural competencies.

Interview Process

The interview process at FAANG+ companies typically spans multiple rounds, each evaluating different skill sets:

Timeline Strategy

The candidate adopted a strategic approach to timing interviews. Four weeks before targeting preferred companies, they began interviewing with organisations of lower priority. This allowed them to build confidence, identify weak areas, and refine their communication style.

For onsite interviews with target companies, the candidate scheduled all rounds within a two-week window. This approach proved advantageous—offers arrived simultaneously, creating leverage for salary negotiations.

Preparation Categories

The interview preparation covered seven distinct categories:

1. Fundamentals – Data structures, algorithms, JavaScript, HTML, and CSS
2. Frontend Trivia – Conceptual questions testing foundational knowledge
3. JavaScript Coding – Practical implementation challenges
4. App Design – Real-world application building
5. Framework-Specific Questions – React-focused technical discussions
6. Frontend System Design – Architectural thinking and trade-offs
7. Behavioural Questions – Soft skills and cultural fit assessment

Technical Rounds

JavaScript Fundamentals

Technical rounds frequently tested core JavaScript concepts. The candidate was asked to explain closures in JavaScript—a consistently popular question across multiple companies. Other topics included:

• The event loop and asynchronous programming
• Prototypal inheritance
• Scope and hoisting

HTML and CSS Concepts

Companies such as Meta assessed foundational web knowledge through targeted questions:
