excellent course. if you want to learn spark from scratch and learn all the concepts then this is the course for you. the instructor is very knowledgeable and explains each concept in easy-to-understand way. The course is updated so all the latest concepts are also covered.

By Kyle Christiaan van Eeden on 9/16/2026

Ansh's passion and enthusiasm for Big Data is highly contagious. Really wish he would drop an advanced Professional Databricks course where we blend AI/ML into the workloads :) Highly recommend all his courses!

By Ratna Gaurav on 8/17/2026

The course was awesome. It explains the pain points of concepts which are difficult to visualize especially for a person new to Data Engineering. I enjoyed and practiced along with it and completed the Databricks Certified Associate Developer for Apache Spark - Python certification with knowledge of the course.

By RASHMITHA A on 8/16/2026

This is my continued course after the Databricks course. As usual, I’m loving your teaching style and the way you break down complex concepts into simple, practical, and easy-to-understand lessons. Looking forward to learning more and building on what I’ve learned so far!

By Robbie Vinglas on 8/14/2026

I was on a compressed time schedule due to an expiring exam coupon. I watched most of the videos, supplemented with some ai summaries. I did not do any course hand's on labs, but have been using Databricks for work. I just passed with a score of 79. This is the second Databricks exam I have cleared using Anch Lamba's courses, and I highly recommend them. He has a talent for making complicated concepts clear.

By Adrian Martinez Santillan on 8/12/2026

So far, so good. I watched your videos on Youtube and I convinced myself I need to complete this course about apache spark, because I want to become a Data Engineer using spark on databricks platform in a while.

By Pranay Birangade on 8/6/2026

The course is well-structured and covers Apache Spark concepts in a clear and practical way. The explanations are easy to follow, and the hands-on examples help reinforce the concepts. It was a great learning experience overall and a good preparation for the Databricks Associate Developer certification. One suggestion for improvement would be to include 2–3 end-to-end live industry projects that cover real-world ETL pipelines, data engineering workflows, and Spark optimization techniques. This would provide a much better understanding of how the concepts are applied in production environments. Overall, it's a great course and definitely worth taking.

By Nitin Patil on 7/23/2026

Excellent course! I learned many new concepts and the explanations were clear and easy to follow. The hands-on approach really helped me understand Databricks and Spark in depth. Most importantly, this course helped me earn my first Databricks certification. Thank You Ansh Lamba for such an amazing course.

By Asmit Basu on 4/26/2026

Please prepare your materials beforehand. It is a waste of time drawing and preparing your visual explanations during the explanation. It just drags the videos longer than expected with no real value addition. This might be a bit harsh, and I am sorry for that. But a lot of my time got wasted watching you drag and drop arrows and tables.

By Anubhav Kumar Gupta on 4/11/2026

This course is a solid choice for both freshers and working professionals. It explains concepts in a simple way with practical examples, making it easy to understand and apply. Overall, a great course to build or strengthen your Spark skills.
