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.

Give a concrete example where you used Excel or a spreadsheet to validate or analyze project data (for example deployment metrics, test results, or telemetry). Describe the dataset, the Excel features you used (pivot tables, Power Query, formulas, macros), any automation you built, and how the analysis influenced a technical decision.

Describe how to implement transactional consistency across microservices that each own their own database. Compare two-phase commit and saga patterns and provide concrete examples of compensating transactions, idempotency, orchestration vs choreography, and tooling or libraries you would use. Explain how you would test these patterns for correctness and failure recovery.

HardSystem Design

Design a secure, multi-region CI/CD system for an organization that builds cloud services and edge firmware. Requirements: reproducible builds, artifact signing and verification, compliance audit trails, geo-replication of artifacts, the ability to roll forward and back across regions, and minimal latency for developer operations. Describe tooling choices, artifact signing approach, replication mechanism, and disaster recovery considerations.

Case study: A production web service's median latency increased from 80ms to 250ms after a dependency upgrade. Outline a step-by-step investigation plan using APM, flame graphs, profiling, load testing, and code review. Explain how you'd isolate the issue, produce a mitigation (rollback or patch), and validate that the fix restores previous performance while preventing recurrence.

Write a Python program or describe an approach to analyze a PCAP file and identify all devices that generated more than 1,000 DNS (UDP port 53) queries within any one-hour sliding window. Explain data structures, libraries (scapy, pyshark), and how you would scale this approach to terabytes of packet captures across many files.
