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.

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.

Design a CI/CD pipeline in Azure DevOps for a polyrepo that contains backend microservices and embedded firmware components. Requirements: run unit tests, cross-compile firmware for multiple targets, build and push container images, run integration tests in a staging environment, and deploy with canary rollouts. Outline pipeline stages, agent pools (hosted vs self-hosted), caching strategy, artifact storage, and rollback mechanism.

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.

Given the transactions table schema: (transaction_id PK, user_id, amount decimal, occurred_at timestamp, device_id int), write an optimized SQL query to compute weekly active users (WAU), average spend per WAU, and top 5 devices by total spend for each of the last 12 calendar weeks. Explain which indexes and partitioning schemes you would add to support these queries at scale and why.

Explain how you would migrate a monolithic application's relational database to a sharded architecture to support 10x growth. Include concrete strategies for schema changes, data migration (cutover or phased), tools (ETL, change data capture), minimization of downtime, and how you would validate correctness after migration.
