Applied Data Science with R

The Applied Data Science with R Interview by Educative, conducted by Edward, is a realistic mock interview for aspiring data scientists. It tests R programming, data manipulation and cleaning (dplyr, tidyr), exploratory data analysis and visualization (ggplot2), statistical modeling and machine learning, reproducible workflows, and performance optimization. Tailored to experience level, it blends conceptual, coding, and scenario-based questions. Candidates practice problem-solving, debugging, and real-world data analysis while building confidence for technical interviews.

Goals:

• Assess understanding of core data science concepts and R fundamentals
• Test data manipulation and cleaning proficiency
• Evaluate exploratory data analysis and visualization skills
• Examine statistical modeling, machine learning, and real-world applications
• Strengthen debugging, performance optimization, and reproducible workflow practices
