Data Science & Analytics Topics
Statistical analysis, data analytics, big data technologies, and data visualization. Covers statistical methods, exploratory analysis, and data storytelling.
Metrics Analysis and Data Driven Problem Solving
Skills for using quantitative metrics to diagnose and solve product or support problems. Candidates should be able to identify relevant key performance indicators such as customer satisfaction, response time, resolution rate, and first contact resolution, detect anomalies and trends, formulate and prioritize hypotheses about root causes, design experiments and controlled tests to validate hypotheses, perform cohort and time series analysis, evaluate statistical significance and practical impact, and implement and monitor data backed solutions. This also includes instrumentation and data collection best practices, dashboarding and visualization to surface insights, trade off analysis when balancing multiple metrics, and communicating findings and recommended changes to cross functional stakeholders.
Data and Trend Analysis with Pattern Recognition
Analyzing quantitative and qualitative data to identify patterns, trends, correlations, and meaningful insights. Skills assessed include descriptive statistics, time series and trend analysis, visualization and dashboarding, hypothesis generation and testing, identifying seasonality and structural changes, distinguishing signal from noise, and synthesizing findings into clear recommendations. For qualitative inputs candidates should demonstrate coding, theme extraction, categorization, and synthesis of transcripts or survey responses. Emphasis is on choosing appropriate methods, validating patterns, avoiding common pitfalls such as confounding and spurious correlation, and communicating insights effectively to stakeholders.
