Performance-testing fundamentals & objectives
Performance risks, service-level objectives, baselines, acceptance criteria, load, stress, spike, endurance, volume, scalability, and test selection.
Assess workload modelling, load, stress, spike and endurance testing, scripting, monitoring, response time, throughput, errors, bottlenecks, capacity planning, reporting, and CI/CD integration.
Measure how candidates translate business demand into realistic workloads, run controlled performance tests, interpret system metrics, isolate bottlenecks, and recommend scalable improvements.

User journeys, concurrency, arrival rates, think time, pacing, transaction mix, ramp-up, duration, peak patterns, test scope, and production realism.
Request recording, parameterisation, correlation, dynamic values, assertions, reusable components, data generation, token handling, and script maintainability.
Load generators, distributed execution, environment parity, network conditions, warm-up, scheduling, data preparation, repeatability, and test controls.
Response time, latency, throughput, transactions per second, error rate, percentiles, concurrency, saturation, Apdex, trends, and result interpretation.
CPU, memory, disk, network, threads, garbage collection, database, caches, queues, dependencies, logs, traces, and root-cause reasoning.
Vertical and horizontal scaling, resource utilisation, limits, capacity forecasts, caching, pooling, query tuning, architecture changes, and validation.
Executive summaries, technical reports, evidence, recommendations, thresholds, performance gates, continuous testing, regression detection, and practical judgement.
Run a consistent assessment with realistic workload, monitoring, and bottleneck-analysis scenarios, structured scoring, and decision-ready reports.
Choose application type, expected load, SLAs, infrastructure depth, tooling expectations, role level, and scenario difficulty.
Candidates model workloads, review scripts, choose test types, interpret charts, correlate metrics, and recommend performance improvements.
Score strategy quality, workload accuracy, scripting knowledge, metric interpretation, diagnostic reasoning, scalability awareness, and practical judgement.
Compare competency breakdowns, scenario decisions, analysis quality, response accuracy, and evidence-based recommendations.
Evaluate workload modelling, load and stress testing, scripting, monitoring, analysis, capacity planning, reporting, and CI/CD skills.
Assess candidates who validate system responsiveness, diagnose bottlenecks, define thresholds, and support reliable releases.
Identify gaps in realistic workload design, percentile interpretation, monitoring, root-cause analysis, scale planning, and continuous testing.
Use realistic performance-testing scenarios, automated evaluation, and explainable score reports to improve performance, QA, SRE, platform, and reliability-engineering hiring.
Use structured tasks, automated evaluation, and clear reports to shortlist stronger engineering candidates faster.
