Data Science & Analytics Topics

Statistical analysis, data analytics, big data technologies, and data visualization. Covers statistical methods, exploratory analysis, and data storytelling.

Analysis to Recommendation and Decision Framing

Ability to move from analysis to a concise, justified recommendation and a pragmatic plan for decision and implementation. Candidates should lead with a clear recommendation or conditional decision, support it with evidence and trade offs, quantify expected business impact, estimate effort and time horizon, and state assumptions and limitations. The skill set includes proposing prioritized action plans and alternative options, anticipating objections, defining monitoring and rollback strategies, translating technical remediation or risk into business terms and measurable success metrics, and tailoring recommendations to stakeholder needs and constraints.

Engineering and Business Outcomes

How engineering work and technical decisions translate into measurable business outcomes and how to demonstrate that linkage. Topics include mapping architecture choices, reliability, performance improvements and developer productivity initiatives to business metrics such as revenue, customer engagement, time to market, cost reduction and customer satisfaction. Candidates should be able to identify engineering metrics to track including latency, availability, error and incident rates, cycle time and deployment frequency, explain instrumentation strategies to capture signals, design measurement plans and experiments to establish causal impact, and attribute observed changes to specific engineering efforts. This topic also covers communicating technical tradeoffs and impact to nontechnical stakeholders, choosing appropriate granularity for measurement, and describing concrete initiatives with their measurement approach and quantified business impact.

Data Driven Problem Solving and Recommendations

Use data to define business problems, form and test hypotheses, identify root causes, and produce clear, prioritized, evidence based recommendations. Candidates should be able to translate a business question into measurable metrics, choose appropriate analyses, segment and compare cohorts, validate assumptions, quantify expected impact and implementation effort, and surface limitations or data quality issues. Good answers explain the analysis steps, any assumptions made, how results would be validated, and the communication approach to ensure stakeholders can act on the recommendation.

Analytical Problem Solving and Hypothesis Testing

Assesses the candidate's ability to convert an ambiguous business problem or signal into structured hypotheses, design analyses or experiments, and draw defensible conclusions. Expect discussion of problem framing, prioritizing hypotheses, selecting data sources, defining cohorts and metrics, designing queries or tests, validating assumptions, controlling for confounders, and communicating actionable recommendations. Core skills include critical thinking, data exploration, statistical reasoning, and translating insights into measurable action plans.

Business Impact Measurement and Metrics

Selecting, measuring, and interpreting the metrics that show whether an initiative, product, or program actually delivered value, and using that evidence to guide decisions. Covers headline outcome metrics (revenue decomposition, customer lifetime value, churn and retention, average revenue per user, unit economics and cost per transaction) alongside operational indicators (throughput, quality, reliability) and how to connect the two. Candidates should be able to distinguish leading from lagging indicators, map operational metrics to business outcomes, form and test hypotheses about what is driving a metric, choose an evaluation window, and recommend changes to what gets measured. Also covers the fundamentals of establishing a valid baseline and comparison group (before/after checks, A/B tests, and other quasi-experimental comparisons when a controlled test is not possible), reasoning about whether an observed change is large enough and reliable enough to act on, and ruling out obvious confounding explanations. Includes quick back-of-the-envelope estimation for order-of-magnitude impact, translating technical or operational metrics into business consequences, building a simple health dashboard for a program or initiative, and communicating results (including uncertainty) as a clear, decision-ready narrative for stakeholders. Depth and specific techniques (for example difference-in-differences, regression discontinuity, or survival analysis) should scale to the role: some interviews probe rigorous experimental design, others probe sound judgment using simpler before/after comparisons.

0 questions

Analytical Background

The candidate's approach to analytical, evidence-based problem solving: how they take an ambiguous question, break it into testable pieces, gather and examine relevant information or data, choose appropriate methods to reach a conclusion, and turn that conclusion into a concrete recommendation or decision. This can show up as quantitative work (statistics, data analysis, experimentation, dashboards) or as qualitative and domain-specific analysis (reviewing logs or incidents, case or contract research, market or process analysis, root-cause investigation). Draw on academic projects, internships, or professional work. Focus on the end-to-end path: how the question or hypothesis was framed, what evidence was examined and with what tools or methods, what trade-offs were considered, and how the resulting insight changed a real decision or outcome.

Metrics and KPI Fundamentals

Core principles and practical fluency for defining, measuring, and interpreting metrics and key performance indicators, applicable across any professional domain. Candidates should be able to select meaningful metrics aligned to business objectives rather than vanity metrics, explain the difference between a metric and a target, and distinguish leading indicators from lagging indicators. Coverage includes decomposing complex outcomes into actionable component metrics, writing precise metric definitions (for example what counts as an active user, a completed case, a qualified lead, or a resolved ticket, depending on the domain), calculating common rate-based metrics such as engagement rate, churn rate, conversion rate, cycle time, or utilization rate, establishing baselines and sensible targets, and interpreting signal versus noise including awareness of statistical variability. Also includes using segmentation and cohort analysis to diagnose metric movements, and recommending two to three meaningful metrics for a hypothetical problem in the candidate's own domain with justification and action plans.

Metrics Selection and Dashboard Storytelling

Focuses on selecting metrics and designing dashboards and reports that directly support stakeholder decision making. Candidates should be able to identify distinct audiences and the specific decisions each audience must make, choose actionable metrics rather than vanity metrics, and balance leading indicators with lagging indicators as well as strategic metrics with operational metrics. This topic covers defining key performance indicators and targets and justifying each metric by the decision it enables, setting data freshness requirements and update cadence, and ensuring instrumentation and data quality to make metrics reliable. It includes dashboard architecture and visual narrative design such as layering from high level summaries to detailed drill down, tailoring views for executives, managers, and operational teams, selecting appropriate visualizations and annotations to guide interpretation, and enabling root cause analysis. Reporting practices are covered, including formatting, distribution channels, and alerting. Governance and metric definition topics include creating a single source of truth, assigning ownership, documenting definitions, and change control. Candidates must also recognize metric interactions and common pitfalls that can make metrics misleading such as aggregation bias, sampling issues, correlation versus causation, and perverse incentives, and propose mitigations. Interview questions typically ask candidates to design metric sets and dashboards for hypothetical scenarios, explain why metrics were chosen based on decisions they support, and describe cadence, distribution, drilling, and governance approaches.

Data Driven Decision Making

Using metrics and analytics to inform operational and strategic decisions. Topics include defining and interpreting operational measures such as throughput cycle time error rates resource utilization cost per unit quality measures and on time delivery, as well as growth and lifecycle metrics across acquisition activation retention and revenue. Emphasis is on building audience segmented dashboards and reports presenting insights to influence stakeholders diagnosing problems through variance analysis and performance analytics identifying bottlenecks measuring campaign effectiveness and guiding resource allocation and investment decisions. Also covers how metric expectations change with seniority and how to shape organizational metric strategy and scorecards to drive accountability.
