 Having good tools to use (like Create React App, Parcel) doesn't eradicate the need for Front End developers to possess good software engineering skills. What will happen if you are the person tasked to build the tools? Great Front End developers (or Software Engineers really) go beneath the abstractions layer, understand how their tools work, and what problems the tool set out to solve. They also constantly seek to challenge and improve the status quo by building better technologies to cater to the ever-increasing demands.
 
-At Facebook, the Front End Engineers are Software Engineers first, domain experts second. Many of the Front End engineers I know at Facebook have a deep understanding of the technical stack and don't just work on stuff related to the browser. At Facebook scale, front end work also involves building a lot of infrastructure to make our front end code base scale well with the growing technical and people needs. That means writing [codemods](https://github.com/facebook/jscodeshift) to do large-scale refactoring, inventing new [UI](https://reactjs.org) [paradigms](http://facebook.github.io/flux/), performant [testing frameworks](https://jestjs.io), creating [type-checkers](https://flow.org) for untyped languages, changing the ways we [fetch data](https://graphql.org) from our servers and [managing it on clients](https://relay.dev). These tools wouldn't exist if the Front End engineers at Facebook didn't possess strong software engineering skills.

-As I mentioned in my post on [coding interviews frameworks](https://www.zhenghao.io/posts/framework-for-coding-interview), I have been interviewing a lot for the past year - not conducting interviews, I was the candidate being interviewed. Most of the interview processes I had with big tech companies consisted of 1-2 system design rounds depending on the level of the role. Unlike traditional back end-focused system design questions, for which you can find lots of prep resources online such as the famous Grokking System Design Interview or System Design Primer, I didn't know what to expect for a front end-focused system design interview as there are very few resources out there talking about this type of interviews.

 Now that I have done a fair amount of system design interviews of both types, I want to give you a summary of what to expect, especially for the front end ones since I have been mostly working on the front end side.
