Technical Skills and Tools Questions

A concise but comprehensive presentation of a candidate's core technical competencies, tool familiarity, and practical proficiency. Topics to cover include programming languages and skill levels, frameworks and libraries, development tools and debuggers, relational and non relational databases, cloud platforms, containerization and orchestration, continuous integration and continuous deployment practices, business intelligence and analytics tools, data analysis libraries and machine learning toolkits, embedded systems and microcontroller experience, and any domain specific tooling. Candidates should communicate both breadth and depth: identify primary strengths, describe representative tasks they can perform independently, and call out areas of emerging competence. Provide brief concrete examples of projects or analyses where specific tools and technologies were applied and quantify outcomes or impact when possible, while avoiding long project storytelling. Prepare a two to three minute verbal summary that links skills and tools to concrete outcomes, and be ready for follow up probes about technical decisions, trade offs, and how tools were used to deliver results.

Outline a migration strategy to move a monolithic Flask-based model serving system to a microservices architecture using a dedicated model server such as TensorFlow Serving or TorchServe and a separate feature service. Include steps for incremental extraction, testing via shadow traffic, canary rollout, data consistency verification, and a rollback plan to minimize downtime and risk.

Describe the Git commands and workflow to do the following: a) create a feature branch from main and push it to remote, b) undo the last commit locally but keep the changes staged or unstaged, and c) permanently remove a sensitive file from repository history. Provide exact commands and briefly explain what each command does and the implications for remote history.

Prepare and deliver a concise 2-3 minute verbal summary that links your machine learning technical skills and tools to concrete outcomes. In your answer include: primary programming languages and self-rated skill levels, top 3 ML frameworks and representative tasks you can perform independently, cloud and containerization experience, one short example with a quantified impact (no long storytelling), and one area you are actively improving.

Describe a practical reproducibility checklist for ML experiments that you would enforce at a team level. Include code versioning, environment capture (Docker/conda), data versioning, random seeds, artifact tracking, and metadata. Recommend concrete tools (git, Docker, MLflow/MLMD, DVC) and how you would enforce compliance via CI or templated project scaffolding.

Describe the monitoring dashboard and alerting strategy you would build for a production fraud detection model. Include the key metrics to track (system, model, and business), example alert thresholds and policies, tools you would use (Prometheus, Grafana, ELK, Sentry), and how you would detect model drift or data quality issues automatically.
