Front-end Engineers are responsible for the code and design of the user-side of web pages and applications. They develop graphics, layouts, and visuals for user engagement. Amazon aims to hire only the best engineers. The competition is so stiff that only 2-3% of the thousands of applicants clear Amazon’s interviews.
Amazon pays its Front-end Engineers well for their skillset, along with other perks. Amazon Front-end Engineer salaries in the US range from $86,400 to $210,000 per year, with an average salary of about $149,485 per year.
To ace your Amazon Front-end interview, you need to hone your skills in CSS, JavaScript, HTML, C++/Java/Python, Angular/Polymer/Backbone/Closure, UI design, system design, and problem-solving in a limited time. To help you put these skills into practice, we’ve compiled a list of Amazon Front-end Engineer interview questions that will get you started on the right track.

We’ll begin with some sample Amazon Front-end interview questions and answers to get a basic idea of what to expect.
Centralized version control system stores all the file versions on a central server, and none of the developers have a complete copy of the files in the local system. So if the central server fails, all the project’s data is lost.
However, in a distributed version control system, all developers have a copy of their system’s code versions. Hence, this system removes the need for a single backup location, enables them to work offline, and ensures that there is no danger when the server crashes.
The command Git Config helps in configuring the user name and email, while Git init is used to initialize a local git repo. The Git Commit command commits changes to the head but not the remote repository, and Git Merge merges a branch into an active branch. Git Push uploads data from the local to a remote repository, and Git Pull gets and downloads data from a remote repository.
As a Front-end developer, visualizing the design for the app closely with the user experience team, testing the web app, taking user feedback, and ensuring the app runs smoothly on different platforms and phones will help create a user-friendly web design.

Q1. Do Front-end developers need to know algorithms for interviews at Amazon?
As a Front-end developer, you generally need to know some standard algorithms. Given the competitive nature of Amazon interviews, you do need to bring your A game. However, in some development roles in other companies, knowing data structures and algorithms is not a requirement and may not be tested in the interview.
Q2. Should I learn Front-end or Full Stack?
In terms of salary, Full Stack developers tend to earn higher wages than Front-end or Back-End developers. It’s often better to hire a candidate with both front and Back-End skills for a slightly higher salary than hiring two people for the same job.
Q3. What are some of the most popular Front-end languages?
HyperText Markup Language (HTML), Cascading Style Sheets (CSS), JavaScript, React, Angular, Vue, jQuery, and Swift are some of the most popular Front-end languages.
Q4. How is data stored on the Front-end?
Data storage options in the Front-end include web storage (local and session storage), indexedDB, cookies, web SQL database, and filesystem API.
Q5. What are some core technical skills required by a Front-end developer at Amazon?
Core skills you need to be a Front-end developer include HTML, CSS, JavaScript, frameworks, libraries, and version control.
