Data Science Notes & Interview Preparation

Data science for analyst and data-role interviews: descriptive statistics, probability distributions, hypothesis testing and confidence intervals, correlation versus causation, then the practical pipeline — data cleaning, missing values, outliers, exploratory analysis and visualisation choices.

The applied half covers SQL for analytics, Python with pandas and NumPy, feature engineering, an introduction to modelling and evaluation, and dashboard and reporting thinking: how to turn a query result into a recommendation a business will act on. Case-style questions are included, since analyst interviews are largely case-driven.

What you'll learn in Data Science

  • Introduction to Data Science
  • Python for Data Science
  • Data Wrangling & Preprocessing
  • EDA & Visualization
  • Statistics for Data Science
  • SQL & Databases for Data Science
  • Machine Learning Basics for DS
  • Tools, Communication & Projects

Why Data Science matters for placements

Analyst hiring tests statistics reasoning and SQL far more heavily than model building, and it almost always includes a case question. Candidates who can explain a metric change or design an A/B test clear these rounds ahead of candidates with longer tool lists.

Frequently asked questions

Which skills are tested in a fresher data analyst interview?

SQL querying, statistics and hypothesis testing, Excel or pandas data manipulation, visualisation judgement, and a business case discussion.

Data science or machine learning — which should I study first?

Statistics and SQL first. They are prerequisites for ML interviews and are the bulk of analyst hiring.

How do I answer a case question about a metric drop?

Clarify the metric and time window, segment by dimension, separate a data issue from a real change, form a hypothesis, then say what you would measure next.
