Hey! I’m Sneha A data engineer who started out just as confused as most freshers — and learned the hard way what actually matters in data interviews and real projects. I have 4+ years of experience as a Data Engineer, working hands-on with SQL, Snowflake, and cloud-based data platforms. Somewhere along this journey, I realized something important: I’m good at breaking down complex data concepts and helping early-career professionals actually understand what they’re learning — not just memorize answers. Today, I help freshers and early-career professionals with: 1. SQL fundamentals & interview questions 2. Snowflake concepts asked in real interviews 3. Clear, structured study notes & eBooks 4. Understanding how data engineering works in real projects 5. Interview mindset & preparation strategy Everything I share here is based on: - What I personally studied - What I’ve used on real projects - What I’ve seen repeatedly asked in interviews My goal is simple — to make data engineering feel less overwhelming and more achievable, especially if you’re just starting out or trying to switch roles. If you want to build strong fundamentals, prepare smartly for interviews, and grow confidently in your data career — you’re in the right place
