JavaScript Language and Libraries

  • What to expect in a FAANG front-end coding interview: Company-specific aspects
  • Challenging JS coding problems: Behavior and usage of "this" keyword. How to bind a function's scope. Arrow functions vs. binding
  • Limiting the scope of variables (a commonly tested concept in interviews). Patterns for creating "private" variables
  • Use built-in JavaScript data structures to solve problems in a time-constrained interview setting. Explain trade-offs between using object literals, maps, sets, and arrays
  • Strategies to solve important problems involving concepts such as currying and callbacks
  • Popular FAANG interview questions on writing code that runs asynchronously, with and without promises
  • Frequently asked coding problems:
  • Existential get() operation using string key
  • Write a function that, until all N arguments are provided, returns a function for consuming more arguments (currying example)
  • Memoization of an async function
2

UI and DOM

  • A structured approach to identifying and solving complex problems that require a combination of HTML, CSS, and JS knowledge (frequently asked in Front-end interviews)
  • How to handle unique UI challenges posed in FAANG interviews by setting up reusable UI components
  • How to consistently position items on the page or within a relative parent (an important skill for UI Developers)

  • Popular FAANG interview question on designing a redux-like state management system from scratch
  • Design and build reusable UI Components: How common components system work
  • How to think, act and articulate like a Front-end architect and tech lead, displaying senior+ signals in System Design interviews using methodical and structured interview strategy
  • Evaluate options, perform trade-offs, and analyze the business impact of modern web development frameworks:
  • Essential understanding of popular UI libraries and frameworks such as React, Angular, etc

Best Suited for

  • Current Front-end/UI Engineers
  • Full-stack Developers

Front-End Engineering Interview Process at Tier-1 Companies

We prepare you for all stages of a typical Front-end Engineering interview process at FAANG and Tier-1 companies.

Initial Technical Screening

  • Coding problem round (easy/medium-level problems on Leetcode)
  • Past front-end project discussion (questions on JS language and its libraries, DOM)

Behavioral Round

  • Questions related to your job experience
  • Discussions on past projects
  • Open-ended questions to gauge if you're a "good fit”

Onsite (4-6 Rounds)

  • 1-2 DSA Coding Rounds: Some companies prefer coding in JS in these rounds
  • 1 Scalable System Design Round: Front-end-focused questions
  • Front-end System Design Round (only for >5 years of experience): Solution is evaluated on performance, accessibility, and modularity
  • 1 Round of Core Front-end: Medium/High difficulty (only for < 5 years of experience)
  • Front-End Fundamentals Round: Knowledge of JS language and libraries, DOM, etc. is tested (problems must be solved using JS, without the assistance of any frameworks like React)
