That's a great question. Data Engineering involves complex pipelines, databases, and cloud platforms, so prepping early helps you stay on track.
💡 Here’s a solid pre-bootcamp checklist:
SQL basics: Understand SELECT, JOIN, WHERE, GROUP BY. Platforms like Mode Analytics or SQLBolt are beginner-friendly.
Python fundamentals: Grasp lists, dictionaries, functions, and file handling—ideal for ETL scripting later.
Command-line familiarity: Basic Bash commands like cd, ls, grep, piping—used when working with Linux-based data nodes.
Data modeling concepts: Know what tables, schemas, and normalization mean.
💬 Grad testimonial: “I spent two weeks pre-bootcamp practicing SQL and Python. When we started with Airflow and Spark, I felt less lost and more confident.”
Typically, full-time bootcamp durations range from 12 to 16 weeks — how prepared you are before the first line of code won't affect the duration, but can seriously improve your experience. A little prep goes a long way. ✅
