Best EdTech Platforms for Aspiring Data Engineers Aiming for Product-Based Companies?

Can anyone recommend the best edtech platforms or institutions for becoming a Data Engineer, especially with the goal of landing a job in a product-based company? I've come across names like Scaler and BossCoder, but I'm looking for honest suggestions based on quality education rather than just flashy promotions. Any guidance, insights, or personal experiences would be greatly appreciated!
