I applied through an employee referral. I interviewed at Discord (San Francisco, CA) in Oct 2017
Interview
The interview process started off with a phone interview with a technical recruiter asking me about the the technologies I know, which front end frameworks I've used, why I like React more than Angular, etc. I only made it as far as the tech screen which was one of the tougher tech screens I've had.
The recruiter asked if I wanted to delay the tech screen as she wanted to invite me to Discord's monthly game night, in which I obviously accepted and have attended the past couple game nights they've had.
Interview questions [1]
Question 1
Build an app from scratch using React and either Flux or Redux for state management. The app will have a button that when you click on it, a modal will open up. The modal will have two divs: one of the left side and one on the right. The left side will have an input that allows a user to add a channel to the list. Once a channel has been added and selected, the right side will have a text box with a save button so anytime a user edits the text in the text box and clicks Save, it will save to the state. When the modal closes, it should maintain the state and whatever channel was selected before the modal was closed. There are major bonus points for making the app look pretty.
Oh yeah, I forgot to mention, you only get 45 minutes to build an entire working, pretty app from scratch. Luckily, I had a boilerplate repo that had React and Redux set up as setting up can potentially take up most of the interview.
Applied -> Recruiter -> HM -> Tech Screen.
First three rounds went great, but the Tech Screen was a very different experience, and felt very out of time with modern software interviewing practices.
I applied online. The process took 1 week. I interviewed at Discord in Jun 2025
Interview
Seemed pretty organized. The "resources"section tells you that they will ask you to build a chat app using TCP clients. I did and practice or reading on it. During the interview, they didn't want you looking at ai responses when you Google. Googling for documentation is allowed.
Got the code working that satisfied all requirements. They asked some questions on how would you do this and that after as well. Got rejected soon after. Not really sure where my performance warranted a rejection but oh well.
Recruiter reached out after seeing my application. They already had asked me to install telnet on my system and about building a chat server using sockets. Did a background reading on that. Got the code working during the interview with some guidance from the interviewers. It should handle multiple clients.
Got rejected next day. No feedback, nothing.
Not sure what the interviewers want these days - a fully working Whatsapp ¯\_(ツ)_/¯ within 1 hr?
