Parium puts candidates in a real Linux terminal with a role-matched infrastructure incident. Send a link in seconds, or build a scenario around your own stack. You get a clear report on how they investigated, what they fixed, and whether they're ready to move forward.
Start with an existing Parium scenario, or work with us to create one around your infrastructure, tooling, and failure modes. Set the role context, difficulty level, and how much guidance the candidate should receive.
Generate an invite from Parium or send it through your existing workflow. Candidates see a branded page with the role, time estimate, and incident brief. There's no account to create and nothing to install. They review the brief and start when they're ready.
Your team gets a structured report: outcome, time taken, investigation path, hint usage, integrity signals, and a written analysis of the candidate's approach. Use the result to decide who progresses and what to probe in the next conversation.
Match the depth of the assessment to where the candidate is in your process.
Short, focused tasks designed to answer one question early: can this candidate perform the practical skill the role requires? API gateway config errors, disk-full incidents, runaway processes. Good for first-stage validation before recruiter calls. 10-15 minutes.
More complete scenarios where candidates investigate across logs, services, networking, and infrastructure state. Azure load balancer failures, Docker container debugging, Kubernetes node pressure. Good for SRE, DevOps, platform, and cloud roles. 20-30 minutes.
Deeper scenarios for senior candidates and specialist roles. Multi-phase cascading failures, GPU diagnostics with escalation decisions, telemetry-driven investigation. Good for senior SREs, platform leads, and on-call ownership roles. 30-45 minutes.
When your stack is specific, we build the assessment around it. Your Kubernetes environment, your GPU monitoring flow, your data centre escalation process, your internal runbooks, your cloud architecture. The scenario reflects the problems your engineers actually deal with.
Two engineers in the same live incident at the same time. Tests coordination, communication, and how candidates handle shared pressure. Available for advanced Kubernetes scenarios through Chaos Mode.
Run a scenario with your own team first to understand what a strong response looks like from people who know your systems. Then use that baseline when evaluating external candidates. Useful for custom scenarios and senior roles. Works well with Team Drills.
A senior engineer and a junior engineer shouldn't receive the same amount of hand-holding. Parium lets you adjust the guidance without changing the underlying incident.
For some roles, you want a bare incident brief and independent investigation. For others, you want to know whether a candidate can follow an operational runbook, interpret telemetry, and execute the right steps safely.
If a mid-level candidate solves it without hints, that tells you something. If a senior candidate reaches for the runbook, that tells you something too.
SENIOR Incident brief only. Candidate drives the investigation. Best for: L3/L4, senior SREs, platform leads, on-call ownership roles MID Incident brief with optional hints on request. Hint usage tracked in the report. Best for: L2, mid-level DevOps, platform, cloud JUNIOR / RUNBOOK Guided operational path with step-by-step procedures. Tests whether candidates can follow process and execute safely under pressure. Best for: L1, graduates, DC technicians, junior admins
More than a score. The report helps your team make better decisions and run better interviews.
Did the candidate resolve the incident? Parium verifies the fix against the scenario's success criteria. You also see what they checked, in what order, and how they moved from symptoms to root cause. The investigation path is often more revealing than the result itself.
Commands, timing, pauses, verification steps, and full session replay. For borderline candidates or senior roles, you can watch the session back and understand exactly how they approached the problem before deciding whether to bring them in.
See whether the candidate solved independently, used hints, followed the runbook, or needed support at a particular stage. Session signals like paste events, tab switching, and timing patterns are surfaced with context for your judgement.
Instead of asking generic technical questions, your hiring manager can probe the exact decisions the candidate made during the assessment. Why did they check the NSG rules before the probe config? Why did they restart the service before verifying the fix? The report gives interviewers somewhere concrete to start.
Send assessment links in seconds. Avoid scheduling unnecessary calls. Keep candidates progressing through your pipeline without waiting for engineering availability.
Parium helps you add a practical technical step without asking your engineering team to run every first-stage screen manually. When candidates pass, you can forward the report directly to the hiring manager with confidence that the person is worth their time.
Review evidence from a realistic technical task instead of relying on CVs, recruiter notes, or inconsistent interview feedback. You can see how the candidate investigated, what they fixed, whether they verified recovery, and where they hesitated.
When you do meet the candidate, you have specific decisions to discuss rather than starting from a blank slate. The report turns a generic technical interview into a focused conversation about their actual work.
Parium doesn't replace interviews. It improves the quality of who reaches them and gives interviewers better evidence to discuss.
For roles where you want hands-on evidence before spending time on manual screening. The recruiter reviews the report and focuses their call on culture, motivation, and logistics rather than technical validation.
For candidates who look promising but need technical validation before reaching the hiring manager. The assessment confirms ability so the HM interview can focus on depth, fit, and team dynamics.
Give your interviewers a concrete report to discuss instead of starting from scratch. They can probe specific decisions the candidate made, rather than asking questions that may or may not reveal real ability.
Run a scenario with your own team first to understand what good looks like. Then use that baseline when evaluating candidates. Especially useful for custom scenarios and senior roles where the bar is subjective.
Candidates receive a link to a branded assessment page. They can see the role, time estimate, and incident brief before they start. There's no account to create and nothing to install. They review the brief, enter the environment, investigate and fix the issue, then verify their work. Most assessments take 10-45 minutes depending on the scenario.
Yes. You can use existing Parium scenarios or we can build custom assessments around your infrastructure, tooling, runbooks, and failure modes. Kubernetes on EKS, GPU clusters with SLURM, legacy systems with custom daemons, your cloud architecture. The scenario reflects the problems your team actually deals with.
No. Assessments can be configured with different guidance levels. Senior candidates get a bare incident brief. Mid-level candidates get optional hints. Junior and operational roles can include runbook-style step-by-step support. The underlying incident is the same at every level, so results are still comparable.
No. Parium gives your team better evidence before or during the interview process. Many teams use the report to decide who should progress and what to discuss in the next conversation. The interview becomes more focused because the interviewer has something concrete to reference.
The assessment environment has no internet access. Parium captures session signals including paste events, tab switching, timing patterns, and command history. These are surfaced in the report with context so your team can make a fair judgement rather than relying on a single flag.
For high-volume roles where you're assessing many candidates for the same position, Screening Links let you create one branded link per role and share it through your ATS, job spec, or recruiter outreach. Candidates self-serve, submissions are deduplicated, and results are scored automatically.
Run a demo scenario yourself, send one to a candidate, or talk to us about building a custom assessment for your role.
