9 Discord Software Engineer Intern Interview Questions (2026)
Discord's SWE intern loop in 2026 is a recruiter screen, an OA, and a 2-3 round virtual interview. Discord runs a small, high-leverage intern program — most interns work directly on a small team with significant ownership. The bar is treated as a future-hire signal, with strong conversion rates for top performers.

Loop overview
Intern flow: recruiter → HackerRank OA (2-3 problems, ~75 minutes) → two to three 45-minute technical rounds. Most reports show two coding rounds plus a behavioral. Some interns get a domain-leaning conversation in place of one coding round. Timeline is typically 4-6 weeks. Internships are based in San Francisco with select remote options.
Behavioral (3)
Walk me through a project you built outside of class.
Frequently askedOutline
Discord weights side projects strongly. Pick one you actually built and can talk about deeply. Walk problem → design → implementation → users (even one user counts) → lessons. Discord bots, hackathon projects, open-source contributions all play well.
Why do you want to intern at Discord?
Frequently askedOutline
Tie to specific Discord usage (a server you run, a community you are in, a bot you wrote). Reference engineering culture if you have read Discord's eng blog. Avoid generic gaming-industry answers — specificity wins.
Tell me about a time you got constructive criticism. How did you handle it?
Occasionally askedOutline
STAR. Pick a real moment. Show you can hear feedback without defensiveness. Discord's culture values direct, kind communication — demonstrate you can do the same.
Coding (LeetCode patterns) (5)
Given a binary tree, return its level-order traversal as a list of lists.
Frequently askedOutline
BFS with a queue. At each iteration, capture the queue size (= current level width), pop that many nodes, collect their values, push their children. O(N) time, O(W) space for W = max width. Walk through edge cases: empty tree, single node.
Implement a function that, given a list of usernames, finds duplicates ignoring case.
Frequently askedOutline
Lowercase each, store in a set, track when a username has been seen before. Return the duplicates. O(N) time and space. Walk through edge cases: leading/trailing whitespace, unicode normalization.
Given two strings, determine if one is a permutation of the other.
Frequently askedOutline
Length check fast-fail. Then either sort both and compare (O(N log N)), or count character frequencies in one and decrement for the other (O(N) time, O(charset) space). Discuss ascii vs unicode. Walk through edge cases.
Implement a function that returns the Nth Fibonacci number using O(1) space.
Frequently askedOutline
Two variables, prev and curr. Loop N times, update prev = curr, curr = prev + curr. O(N) time, O(1) space. Walk through edge cases: N=0, N=1. Discuss matrix exponentiation for O(log N) if asked.
Given a list of intervals, merge overlapping ones.
Frequently askedOutline
Sort by start. Walk the list, merging current with the last accepted if they overlap (start <= last.end). Else, push as a new interval. O(N log N) sort + O(N) walk. Walk through edge cases: empty input, single interval, fully-contained.
Technical (1)
How would you build a small bot that responds to a slash command?
Occasionally askedOutline
Domain-conversational. Walk through: register the slash command with the Discord API, receive interaction webhook, parse the command + parameters, respond within 3 seconds (or defer with a follow-up). Discuss authentication (bot token), rate limiting, error handling. Bonus: have you actually built one.
Discord interview tips
- Side projects matter at Discord. A Discord bot, a hackathon project, an open-source PR — any of these can carry the behavioral round.
- The OA gates everything. Practice HackerRank-style problems with timed runs.
- Coding rounds favor classic data structures + algorithms. Trees, graphs, hash maps come up often.
- Have one strong project story ready. The interviewer will dig into design decisions.
- Intern conversion at Discord is strong for high performers. Treat it as a 12-week extended interview.
Frequently asked questions
How long is Discord's SWE intern interview process in 2026?
Most reports show 4-6 weeks from OA to offer.
How many rounds are in Discord's SWE intern onsite?
Two to three virtual rounds in 2026, typically 45 minutes each. Two coding rounds plus an optional behavioral or domain-leaning conversation.
Does Discord hire international SWE interns?
Yes, Discord has sponsored F-1 OPT/CPT for interns. Confirm with your recruiter for 2026.
Do I need to have built a Discord bot to interview?
No, but it strongly helps. If you can talk about a real bot you shipped — design, users, lessons — that single story can carry the behavioral round.
What language should I use for Discord intern interviews?
Python, JavaScript/TypeScript, or any mainstream language you know well.
