Frequently Asked Questions:
What does a Data Scientist do?
A Data Scientist turns raw data into insights and models that change decisions: experimentation, statistical analysis, predictive models, and the storytelling that gets stakeholders to act. The role spans SQL, Python, statistics, and product judgment. Strong data scientists know which questions are worth answering and which models are worth shipping; the rest is execution.
How much does it cost to hire a Data Scientist?
The average U.S. Data Scientist salary is $10,200 per month compared with an average Latin American salary of $3,250 per month, creating potential savings of up to 68%. LatAm produces strong candidates for this role from countries like Argentina, Brazil, Colombia, and Mexico, many with years of remote U.S.-team experience and direct exposure to the same tools and processes used in U.S. companies.
Can a U.S.-based company hire a remote Data Scientist from Latin America?
Yes, and most modern companies already do. South contracts the hire locally, handles compliance and payroll, and bills you monthly. The person joins your tools (Slack, Notion, Jira, GitHub, Zoom) just like a domestic employee. Time-zone alignment is the unlock: live meetings, real-time collaboration, and same-day decisions all work without the async lag you get hiring in EMEA or APAC.
What skills should I look for when hiring a Data Scientist?
Look for someone who has shipped a model or an experiment that changed a real decision, not just a notebook. Ask about a result that contradicted leadership's intuition and how they communicated it. Strong DSs are bilingual: rigor with stakeholders, and pragmatism with numbers.
What tools and software should a Data Scientist know?
Python (pandas, scikit-learn, statsmodels), SQL on Snowflake, BigQuery, or Redshift, Jupyter, dbt, an experimentation platform like Eppo or Statsig, and a viz tool like Looker or Mode. ML stack: PyTorch or TensorFlow if they ship models.
How is a Data Scientist different from a Data Analyst?
A Data Analyst answers questions with data: dashboards, ad-hoc queries, descriptive analysis. A Data Scientist goes further: experimentation design, predictive modeling, and statistical inference. The bar is higher in both technical depth and business impact. Hire a Data Analyst first; add a Data Scientist when you have a real prediction or experimentation problem.
How can South help me hire a Data Scientist?
South vets LatAm talent through structured interviews, work-sample tasks, and reference checks. You see a shortlist in seven to ten days, run your own interviews, and onboard in two to three weeks. South handles the contract, monthly payments, and offers a replacement guarantee. Schedule a free call here to get started!
Interview Questions:
- Walk me through an experiment you ran that changed a real decision.
- How do you decide whether to A/B test or to just ship?
- Tell me about a model you shipped to production. What was the eval metric?
- Write the SQL for a 28-day rolling retention curve.
- How do you explain a non-significant result to a VP who wanted significance?
- Compare bootstrap confidence intervals and t-tests. Pick one and defend it.
- Walk me through your feature engineering for a churn prediction model.
- How do you handle multiple comparisons in a 50-segment analysis?
- Tell me about a time you found leakage in a model. How did you fix it?
- What is your stance on causal inference for product decisions?
