Relevant Technical Experience and Projects Questions

Describe the hands on technical work and projects that directly relate to the role. Cover specific tools and platforms you used, such as forensic analysis tools, operating systems, networking and mobile analysis utilities, analytics and database tools, and embedded systems or microcontroller development work. For each item explain your role, the scope and scale of the work, key technical decisions, measurable outcomes or improvements, and what you learned. Include relevant certifications and training when they reinforced your technical skills. Also discuss any process improvements you drove, cross functional collaboration required, and how the project experience demonstrates readiness for the role.

You notice a service's p99 latency has increased by 50% after a deployment. Describe a step-by-step debugging approach using APM/tracing (Jaeger/Zipkin), logs, metrics, and network captures to determine whether the cause is a code change, resource exhaustion, configuration change, or an external dependency regression. Explain what you would measure first and why.
