PrepVector SQL Challenge - Week 1 Updates!
Halfway through the PrepVector SQL Challenge! 🚀 Check out key highlights on how participants are sharpening their skills and tackling real-world SQL problems.
🎉 We’re halfway through the PrepVector SQL Challenge! 🎉
What started as a simple idea—a fun, hands-on SQL challenge—has grown into something far bigger than we imagined! When Siddarth Ranganathan, Sai Kumar Bysani, and I first discussed this, our goal was clear: help learners gain real-world problem-solving experience with SQL.
SQL isn’t just about writing queries. In the industry, it’s about solving real problems efficiently, handling data at scale, and thinking critically. Through this 15-day challenge, we’re replicating that experience—helping you hone your skills, think strategically, and push your limits.
Let’s take a look at how far we’ve come this week! 🚀
👋 Hey! This is Manisha Arora from PrepVector. Welcome to the Tech Growth Series, a newsletter that aims to bridge the gap between academic knowledge and practical aspects of data science. My goal is to simplify complicated data concepts, share my perspectives on the latest trends, and share my learnings from building and leading data teams.
