Parium simulates real-world data center operations failures across GPU fleets, power distribution, and hardware infrastructure. Evaluate how candidates respond to hardware instability and live production risk.
No vendor trivia. No whiteboard diagrams. Just real operational decision-making.
Candidates enter a scenario modeled on real data center environments. They must diagnose failures, follow escalation protocols, and verify restoration while telemetry updates in real time.

Telemetry updates as candidates diagnose and remediate
Structured to evaluate both procedural compliance and systems thinking.
We measure how candidates diagnose hardware failures, follow escalation protocols, and maintain operational safety under production conditions.
Each scenario is calibrated for the complexity and autonomy expected at that tier. L1 tests runbook compliance, L3 tests expert-level GPU cluster operations and hardware diagnostics.
Advanced GPU diagnostics with Xid 79 PCIe error. Candidates must diagnose hardware communication failure, distinguish between driver issues and physical problems, and apply appropriate remediation without affecting healthy nodes.
2x GPUs offline due to driver conflict. Candidates must use lspci to confirm hardware, check loaded kernel modules, identify driver conflicts, and safely restore GPU functionality.
Service down due to full disk. Candidates must investigate log directories, identify oversized files, safely clean space while preserving required logs, and restore service. Tests independent triage.
Service failing health checks due to malformed config file. Tests basic Linux navigation, file editing, service restart procedures, and verification. Includes detailed runbook to follow.
We replicate your rack topology, GPU configuration, cooling model, redundancy architecture, and escalation structure. Designed to reflect real operational risk.
Talk to UsEach assessment produces a structured report suitable for both technical leads and HR review. Designed for data center operations hiring at scale.
See when each diagnostic step was taken and how long it took to reach conclusions.
Did they escalate at the right time? Too early? Too late?
Quantified adherence to standard operating procedures and runbooks.
Any unsafe power actions, bypassed safeguards, or protocol violations.
Did they correctly identify the failure domain and root cause?
Side-by-side benchmarking across multiple candidates on the same scenario.
No. It evaluates decision-making before physical intervention. You still need to assess physical skills separately.
Yes. Scenarios scale in complexity and autonomy expectations. L1 tests runbook following, L2 tests independent triage, L3 tests expert diagnostics.
Yes. We model your specific hardware configurations and custom GPU clusters.
Yes. Scenarios include training-load stress, GPU failure cascades, thermal imbalance, and power redundancy risk.
Run the assessment yourself and see how candidates handle hardware failures under pressure.
