Apache Spark - Beyond Basics and Cracking Job Interviews (Udemy.com)

I am a Senior Data Engineer at Amazon, and I can confidently say that he is one of the best Data Engineering tutors I have come across so far. Here are the reasons for my recommendation: 1. He explains concepts at a very fundamental level in a way that is easy to understand. You gain deep insights without having to invest an excessive amount of time. At times, it felt like a close friend was sharing internal system knowledge and practical insights that others usually hesitate to share. 2. His course is concise yet highly focused on what truly matters. There is no unnecessary content — just clear, relevant, and impactful learning. 3. His English is smooth, and his voice is calm and pleasant, which makes it easy to follow along even during longer sessions.

Extremely detailed course that covers critical architecture and performance areas. It serves as an excellent refresher for experienced Spark developers and is a must-watch for anyone looking to understand Spark's internal mechanics and how to solve real-world performance challenges.

After many failed trials of finding the good pyspark course, finally my senior recommended me this one. And it is so well explained and described that not a single topic goes without you fully understanding it.

Spark internals are explained clearly. Only thing is I had to slow down the video to 0.75X as I am not able to absorb content in the original recorded speed of the trainer.

A really in depth course on the internal working of Spark focused on the exam. However Shuffle operations the map and reduce part of it could have been explained in more detail. they are just slightly touched that too in a Q&A video. Overall I would like to recommend this course to anyone willing to learning spark beyond the basics and optimising your queries.

Fast paced but, in general terms, a really well explained matter. Maybe sometimes deepening into details may feel a bit confusing or overwhelming, but I also liked the complexity. Nice course!

Great course! Only thing missing is the course slides. If they can be provided under recourse section, it would be much appreciated. Students can use the slides for quick reference.

Explanation is very clear even a person who doesn't have knowledge also can understand 90% of the content, and I'm one of them. Thanks to Prashant sir for sharing his knowledge.

Excellent. The way you explained each concept in details is awesome. I will highly recommend to take this course if you are working on Spark to become a more advanced developer.
