Data scientist who evaluates AI model outputs on statistics and machine learning, creates expert-level data science problems, and provides feedback for quantitative reasoning.
What you would do
- Evaluate AI-generated outputs on statistics, machine learning, experimentation, and quantitative problems
- Develop high-quality prompts, datasets, and benchmark solutions for rigorous AI testing
- Identify methodological flaws, statistical errors, and weak reasoning in model responses
Who they want
- At least one year of recent experience at top tech, finance, or research companies
- Strong expertise in statistics, machine learning, data analysis, and experimentation design
- Demonstrated ability to communicate technical and statistical ideas clearly in writing
- Based in an English-speaking country
Main skills
What the interview asks about
1.Statistical reasoning and error detection
The core of this work is spotting when AI makes statistical errors or reaches invalid conclusions. This tests your statistical rigor and ability to explain flaws clearly.
For example: “An AI analyzes A/B test results with 50 users per group, calculates a p-value of 0.08, and concludes no meaningful difference exists. What statistical issues does this reasoning overlook?”
2.Machine learning methodology evaluation
Evaluating ML work requires understanding problem framing, model selection, and validation rigorously. This tests whether you assess ML approaches critically.
For example: “An AI proposes a random forest to predict churn, trained on 5 years of data but validated only on the most recent 3 months. What concerns would you raise?”
3.Expert problem and dataset creation
Designing problems that meaningfully test AI capabilities requires deep domain knowledge. This evaluates your ability to create scenarios revealing gaps in AI reasoning.
For example: “Design a data science problem that exposes weaknesses in how an AI model distinguishes causal inference from correlation. Why does this problem reveal that gap?”
4.Quantitative feedback and communication
Your feedback trains the AI model; it must identify flaws clearly and explain why solutions work or fail. This tests whether you communicate technical issues precisely.
For example: “Write feedback on an AI response to a statistics question where it made an assumption that's commonly wrong. How would you explain why this assumption breaks the analysis?”
A task you may get
Evaluate an AI-generated response to a data science or statistics problem, identify flawed methodology or reasoning, and provide structured feedback explaining what a correct approach requires.
How to prepare
- Review 2-3 real data science problems you've solved at work - bring details about statistical or ML methods used
- Prepare to discuss a time you found a subtle statistical or methodological error in analysis or modeling work
- Review common statistical misconceptions and how they surface in real machine learning work
