Hire DevOps engineers who have already fixed it once.
Every candidate gets an isolated cloud environment with a real system in it: a service that will not start, a cluster that is wide open, a deployment that was never written. What comes back is what they actually did.

A DevOps interview is mostly the candidate describing DevOps

What is at stake
The mistake shows up at three in the morning
Nobody finds out a DevOps hire was wrong in a code review. They find out during an incident.
Where it shows
The first incident
The gap between describing a rollback and performing one is invisible in an interview and obvious at 3am.
Who pays for it
The on-call rota
A hire who cannot hold the pager makes the rota worse for everyone who can.
What an interview cannot ask
Show me
Access to a real system is the one thing an interview cannot give a candidate. It is the only thing this replaces.
Live in an afternoon

Candidates work when it suits them
Each candidate gets their own machine, a real one, with a real task already loaded.

The shortlist ranks itself
Scoring runs automatically against the task you set, so the ranking builds as candidates finish.

The published missions are deepest here
These are real systems rather than exercises: a Go service that has to come back up on its own under systemd, a Node and Postgres stack that will not talk to itself, a Kubernetes deployment that has to be hardened, a web server that has to be built with Ansible.
- Every mission runs in an isolated cloud environment, one per candidate
- Scored automatically on what the system actually does at the end, not on an answer
- You can import your own scenario as a .zip and run it yourself before you send it

The questions we get
Straight answers on how the tests, the scoring and the credits actually work.
What is a Scalyz lab, exactly?
A real virtual machine with a real mission, not a quiz. The candidate works with the same tools they'd use on the job, and the session is recorded so you can review the evidence later.
Who scores it?
Automatically. The checks run against what the candidate delivered, and you get a report broken down skill by skill, so no one on your team grades a thing by hand.
Can they cheat with AI?
A chatbot can suggest commands, but it can't run a live system for the candidate. The mission has to be done on the machine itself, and any cheating signals come with context, so you can judge them yourself.
What do I pay?
In credits: one per candidate. A credit is reserved when you send an invitation and released if it expires unused. You pay per candidate tested, never per user.
Can I bring my own exercise?
Yes. Upload your files as a .zip, rename the mission to match your role, and run it yourself for one credit first. What you tested is exactly what candidates get.
What is it like for candidates?
On their own time. They start when it suits them, work with real tools on a real machine, and finish in one sitting. It runs in English and French.
Your next DevOps first round runs itself
Book a demo and we will run one of these missions on your own open role.
