The interview for how
engineers actually work.

With OpenRound, candidates get full access to AI tools. They solve real problems on a real codebase. The tools they use at work are the tools they interview with.

README.md
Converge — Collaborative Document Sync
Context
A lightweight whiteboard tool has no real-time sync. Two designers editing the same document silently overwrite each other's work. The team has lost hours of layout work to this problem multiple times.
Your Task
Build a real-time sync layer over WebSockets — property-level conflict resolution, optimistic local updates, and tree-structure operations that compose cleanly under concurrency.

The problem

Your engineers ship with AI every day.
Then why interview candidates without it?

Every method you're using to evaluate engineers was designed before AI changed how they work.

R.I.P.
Leetcode2005 — 2025

Tests memorization, not engineering.

Your best engineer hasn't reversed a linked list since college. You're filtering for the wrong skill.

R.I.P.
Take-homes2010 — 2025

One-shotted by AI in 7 minutes.

Candidates paste the brief into Claude and submit the result without understanding the problem. The entire exercise gives zero signal.

R.I.P.
Work trials2015 — 2025

Expensive, slow, and don't scale.

A week-long trial for every candidate is a luxury you can't afford. Good candidates won't wait.

R.I.P.
DSA2008 — 2025

Eaten by AI cheating tools for lunch.

Candidates simply read out the answer from tools like Cluely. Lack of real world use means both the candidate and your interviewer are disinterested.

What is OpenRound

A new interview format built for how engineers actually work.

Candidates solve real problems with AI in a dev friendly environment.

Core

Real problems on real codebases

Not algorithmic puzzles. Candidates work on a feature, a bug, an end-to-end task — on an existing codebase matched to your stack. The kind of work they'd do in their first week.

AUTH-347High
Fix the token refresh race condition

Summary

Concurrent API calls trigger simultaneous token refreshes, causing 401 cascades. Fix the race condition and add retry logic.

Tools

Work with AI to solve problems

Candidates get access to AI in their CLI — similar to how they interact with Claude Code or Codex. No separate chatboxes that feel unnatural.

Assessment

Designed for AI-native workflows

Assessments mirror how real work happens now: identify, architect with AI, implement, validate. Every stage is a signal. Every decision is observed.

Workflow stages0/4
Identify

Read codebase, find the bug

Architect

Plan fix with AI assistance

Implement

Work with AI to write code

Validate

Run tests, verify behavior

Evaluation

Fair, customizable evaluation

Every candidate is evaluated on evidence-backed scores across dimensions you define — tuned to what actually matters for your team.

Interactive by design

Candidates can ask clarifying questions just like they would on the job. Type /askPM to get real-time answers from a simulated product manager.

❯ /askPM Should the endpoint return paginated results or the full list?
PM: Paginated — default 25 per page. The client handles infinite scroll.
Setup

Candidate Experience

Give your candidates a 10 star experience.

The best engineers judge you by your interview. OpenRound is designed so candidates walk away impressed — whether they get the offer or not.

No Leetcode

No one reverse-sorts a linked list at work. We test what actually matters — how engineers think, build, and ship.

Real world problems

Candidates work on a real codebase with real tickets. The interview feels like day one on the job, not a pop quiz.

Respectful of time

One 90-minute session replaces 2 rounds of interviews. Your best candidates will love your interview loop, instead of dreading it.

Testimonial

Redefining assessments — one team at a time.

Openround is the new benchmark in interviews. Nothing comes close to it in terms of signal quality and candidate experience. This has changed hiring for us.
