Contract

the QUESTIONS are at the bottom

We have a permanent position for a Data Scientist in Arlington VA. Due to the nature of work you must be a US Citizen to apply and be able to obtain a public trust. This role is 2 times a month on site.

Please answer the questions and return for submittal.

Here are the screening questions:

For this role, I'd use questions that force candidates to give specific examples rather than simply confirm they've used Python, SQL, Azure, etc. These five should work well for a first-round recruiter/technical screen:

1. Programming & SQL: "Walk me through a recent project where you used Python and SQL to solve a complex data problem. What did you personally build, how complex was the data, and what was the final business outcome?"
2. Listen for: 5+ years of hands-on coding, strong SQL/relational database skills, Python proficiency, and clear individual contribution.
3. Machine Learning / Advanced Analytics: "Tell me about a production or business-facing project where you applied machine learning, NLP, AI, text/data mining, or another advanced statistical technique. What problem were you solving, what approach did you choose, and how did you evaluate whether it worked?"
4. Listen for: 3+ years of substantive advanced analytics experience-not simply exposure to AI/ML tools-and the ability to explain model selection, validation, metrics, and measurable business impact.
5. Azure/AWS & Databricks: "Describe something you've built or supported in Azure or AWS. Specifically, what experience do you have with Databricks, Azure Data Factory, Data Lake, or comparable cloud services?"
6. Listen for: At least 6 months of genuine hands-on cloud experience. Strong candidates should be able to describe architecture, pipelines, notebooks/jobs, storage, security/access, and their personal responsibilities.
7. ETL / Data Engineering & Troubleshooting: "Suppose you're given data from several sources with inconsistent formats, missing values, duplicates, and questionable data quality. How would you design the ETL process and validate the resulting dataset before it was used for analytics or reporting?"
8. Listen for: ETL design, data profiling, transformation, SQL/Python, validation/testing, data-quality controls, lineage/documentation, debugging, and awareness of security requirements.
9. End-to-End Delivery & Communication: "Give me an example of a data product you took from business requirements through development and deployment. How did you work with business users, IT/database teams, document your methodology, test the solution, and communicate the results to nontechnical stakeholders?"
10. Listen for: Full SDLC experience, stakeholder management, documentation, testing/debugging, BI/Power BI experience, teamwork, and the ability to translate between technical and business audiences.
