Data Science & Analytics Topics
Statistical analysis, data analytics, big data technologies, and data visualization. Covers statistical methods, exploratory analysis, and data storytelling.
Attribution Modeling and Multi Touch Attribution
Covers the theory and practice of assigning credit for conversions across marketing touchpoints. Candidates should know single touch models such as first touch and last touch, deterministic multi touch models like linear and time decay, and algorithmic or data driven models that use statistical or machine learning techniques. Discuss the pros and cons of each approach including bias introduced by simple models, the data and engineering requirements for algorithmic models, and trade offs between interpretability and accuracy. Topics include model selection aligned to business questions, dealing with long purchase cycles, cross device and cross channel journeys, limitations of deterministic attribution, approaches to model validation, and how attribution differs from causal incrementality testing.
Data Storytelling and Insight Communication
Skills for converting quantitative and qualitative analysis into a clear, persuasive narrative that guides stakeholders from findings to action. This includes leading with the headline insight, defining the business question, selecting the most relevant metrics and visual evidence, and structuring a concise story that explains what happened, why it happened, and what the recommended next steps are. Candidates should demonstrate tailoring of language and technical depth for diverse audiences from engineers to product managers to executives, summarizing trade offs and uncertainty in plain language, distinguishing correlation from causation, proposing follow up experiments or investigations, and producing concise executive summaries and status reports with an appropriate cadence. Interviewers evaluate the ability to persuade and align cross functional partners, answer questions about data validity and methodology, synthesize qualitative signals with quantitative results, and adapt presentation format and level of detail to the decision maker.
Business Impact Measurement and Metrics
Selecting, measuring, and interpreting the business metrics and outcomes that demonstrate value and guide decisions. Topics include high level performance indicators such as revenue decompositions, lifetime value, churn and retention, average revenue per user, unit economics and cost per transaction, as well as operational indicators like throughput, quality and system reliability. Candidates should be able to choose leading versus lagging indicators for a given question, map operational KPIs to business outcomes, build hypotheses about drivers, recommend measurement changes and define evaluation windows. Measurement and attribution techniques covered include establishing baselines, experimental and quasi experimental designs such as A B tests, control groups, difference in differences and regression adjustments, sample size reasoning, and approaches to isolate confounding factors. Also included are quick back of the envelope estimation techniques for order of magnitude impact, converting technical metrics into business consequences, building dashboards and health metrics to monitor programs, communicating numeric results with confidence bounds, and turning measurement into clear stakeholder facing narratives and recommendations.
Data Analysis and Insight Generation
Ability to convert raw data into clear, evidence based business insights and prioritized recommendations. Candidates should demonstrate end to end analytical thinking including data cleaning and validation, exploratory analysis, summary statistics, distributions, aggregations, pivot tables, time series and trend analysis, segmentation and cohort analysis, anomaly detection, and interpretation of relationships between metrics. This topic covers hypothesis generation and validation, basic statistical testing, controlled experiments and split testing, sensitivity and robustness checks, and sense checking results against domain knowledge. It emphasizes connecting metrics to business outcomes, defining success criteria and measurement plans, synthesizing quantitative and qualitative evidence, and prioritizing recommendations based on impact feasibility risk and dependencies. Practical communication skills are assessed including charting dashboards crafting concise narratives and tailoring findings to non technical and technical stakeholders, along with documenting next steps experiments and how outcomes will be measured.
Problem Framing and Data Driven Recommendations
Covers the end to end process of turning ambiguous business questions into clear, actionable solutions using structured thinking and empirical evidence. Includes decomposing complex problems into root causes and manageable components, defining success criteria and key metrics, and selecting appropriate analytical approaches and frameworks. Encompasses extracting, cleaning, and synthesizing raw data into insights, using quantitative and qualitative evidence to generate and evaluate multiple solution options, and applying trade off and prioritization frameworks such as impact and effort. Requires producing evidence backed, prioritized recommendations with implementation considerations, sequencing and monitoring plans, and communicating findings clearly to stakeholders with varying levels of technical knowledge.
Marketing Analytics and Measurement
Covers the design, implementation, and interpretation of marketing measurement systems that connect marketing activities to business outcomes. Topics include defining and prioritizing key performance indicators across the marketing funnel from awareness and consideration through conversion, retention, and advocacy. Core metrics and diagnostic measures include click through rate, conversion rate, impressions, engagement and session metrics, bounce rate, lead volume, cost per lead, cost per acquisition, customer acquisition cost, customer lifetime value, return on advertising spend, return on investment, marketing influenced revenue, pipeline contribution, marketing qualified leads, sales accepted leads, and lead to opportunity conversion rates. Measurement frameworks and methods include last click and multi touch attribution approaches, marketing mix modeling, incrementality testing and holdout group experiments, randomized controlled experiments and split testing, and considerations for statistical significance, sample size, noise, and distinguishing correlation from causation. Also covers data and instrumentation concerns such as tagging and event tracking, data flows from advertising and marketing systems into analytics platforms and data warehouses, data quality and identity resolution, and privacy driven tracking limitations. Reporting and dashboard design topics include selecting leading versus lagging indicators, balancing granular event level dashboards with executive level summaries, setting realistic targets and benchmarks, communicating findings and recommended actions to stakeholders, and using measurement to inform channel mix, campaign optimization, and budget allocation decisions.
Data Driven Recommendations and Impact
Covers the end to end practice of using quantitative and qualitative evidence to identify opportunities, form actionable recommendations, and measure business impact. Topics include problem framing, identifying and instrumenting relevant metrics and key performance indicators, measurement design and diagnostics, experiment design such as A B tests and pilots, and basic causal inference considerations including distinguishing correlation from causation and handling limited or noisy data. Candidates should be able to translate analysis into clear recommendations by quantifying expected impacts and costs, stating key assumptions, presenting trade offs between alternatives, defining success criteria and timelines, and proposing decision rules and go no go criteria. This also covers risk identification and mitigation plans, prioritization frameworks that weigh impact effort and strategic alignment, building dashboards and visualizations to surface signals across HR sales operations and product, communicating concise executive level recommendations with data backed rationale, and designing follow up monitoring to measure adoption and downstream outcomes and iterate on the solution.
Measurement Design and Analysis
Practical measurement design and analytic techniques for producing reliable metric signals and proving impact. Includes instrumentation and tracking plans, experiment selection and validation, attribution modeling and its limitations, sample size and statistical considerations, identifying confounding variables, and reasoning about correlation versus causation. Also covers tradeoffs in data collection and data quality checks, cohort and segmentation design, baselining and threshold setting, designing dashboards and monitoring cadence, and connecting engineering and telemetry data to business outcomes. Candidates should be able to write clear measurement plans and success criteria, describe experiment and validation approaches, and explain how to operationalize results through reporting and iteration.
