Sprint simulation·Coming soon

Coding interviews are broken.
We replaced them with a sprint.

Tervlon is a sprint simulation. Developers work a real ticket backlog with AI teammates while we measure how they think, communicate, and build. The report shows what an interview can’t.

Or talk to the team

Developers prove how they actually work. Hiring teams hire on real signal. Academies graduate engineers ready for the job.

The problem

Coding assessments ask candidates to solve puzzles in isolation. Real engineering isn't a puzzle — it's a conversation. You read tickets, ask teammates, handle interruptions, and ship. The skill that matters is how you work alongside people, and no existing assessment measures it.

Tervlon measures it.

How it works

Four parts. One day.

A Tervlon sprint has structure. Here's what shows up.

The Sprint

Five tickets. One workspace.

Every sprint is a structured engineering day. Real tickets with acceptance criteria, a live terminal, pre-written tests, and a time estimate. You ship ticket by ticket, just like joining a real backend team mid-sprint.

The Team

Four teammates, not chatbots.

Sarah (PM), Marcus (senior), Priya (peer), and James (reviewer). Each has a distinct voice, a specialty, and a role. They ping you unprompted, answer what they'd answer, and stay quiet otherwise.

The Standups

You can't dismiss an interruption.

At unscheduled moments, Sarah pulls you into a sync. A countdown starts. You can delay by 30 seconds once, then it auto-joins. You're measured on how you explain your code — not just whether you wrote it.

The Report

Six dimensions. One narrative.

When the sprint wraps, Sarah closes the day with a retrospective. The report reads like a post-sprint summary, not a scorecard. Scores sit in the margin; the story of what you did is the centerpiece.

What we measure

Six dimensions. One story.

Most assessments give you a single number. Tervlon scores every sprint across six dimensions, because a developer who ships correct code and a developer who ships correct code while coordinating with their team are different hires.

The signature moment

Real teams don't schedule interruptions.

Standups happen when the PM calls them. You can't dismiss one, and you can't prepare for it. That's the point.

01

The toast drops in.

Sarah's avatar appears at the top of your screen with a countdown ring. You have seven seconds to brace yourself.

02

The sheet slides up.

The workspace dims. A standup room rises over your work. You're not gone — you can see your code behind. But you're not coding anymore either.

03

Your comprehension is measured.

Sarah asks you to walk through what you built. Your answer is transcribed and scored. Silence costs more than a wrong answer.
