Live Cohort : Master The SQL & Advanced SQL Programming

"Really insightful and well-structured masterclass by Rahul Neekhra on the Data Engineers & Data Architects Interview Playbook. Rahul explained the interview process and expectations in a very practical and easy-to-understand way. I especially liked the focus on how to approach real-world scenarios and present our experience effectively rather than simply memorizing answers. The session provided a clear perspective on what interviewers look for and how to prepare with the right mindset. Overall, a very valuable session for anyone preparing for Data Engineering or Data Architecture interviews. Highly recommend Rahul as an instructor!"

"This master class exceeded my expectations. I learned about the latest Data Engineering technologies, project architecture, and interview preparation strategies. The session was highly valuable for both beginners and experienced professionals."

"The masterclass was very well organised. Satisfied with the contents on offer in the 3 hours."

"I booked a free career guidance session with Rahul Sir through Practyc. Before the session, I was a bit skeptical and wondered if it would mainly be about selling his cohort. However, my experience was completely different. Rahul sir is genuinely experienced and took the time to understand my background, goals, and current situation. Instead of giving generic advice or pushing any course, he provided a clear and practical roadmap tailored to my career aspirations. The session helped me solidify my understanding of the field and gave me much more clarity about the next steps I should take. I really appreciate his honest guidance and the value he provided during the session. If you're looking for genuine career advice from someone who truly understands the industry, I would definitely recommend booking a session with him."

"I attended the ETL Cohort demo session and later booked a 1:1 call with Rahul to clarify a few doubts before enrolling. As someone with 8 years of experience working as a Senior Data Engineer, primarily on Azure and Databricks, I was initially a bit skeptical because Databricks wasn't a major part of the syllabus. However, the conversation completely changed my perspective. Rahul explained how technologies like Databricks and Snowflake are essentially platforms built on strong data engineering fundamentals, and why mastering the core concepts is far more important in the long run. We discussed topics like Data Modeling, Data Warehousing, SCDs, Lakehouse architecture, Governance (PII, masking, compliance), and Streaming—not just what they are, but why they exist, when to use them, and the intuition behind them. That practical way of explaining concepts really stood out. What impressed me the most was his patience. Although the session was scheduled for 15 minutes, he spent over 30 minutes answering every question without rushing. At no point did it feel like a sales call—it was an honest technical discussion focused on clearing my doubts. Based on this interaction, I've decided to enroll in the cohort. While the real experience will ultimately depend on how the batch is delivered, my first impression has been very positive, and I'm genuinely looking forward to the learning journey. If you're someone who has doubts or is unsure whether to join, I'd definitely recommend booking a 1:1 session first. It helped me make an informed decision. Thanks, Rahul, for taking the time and patiently addressing all my questions."

"Thank you Rahul for clear guidance and instructions on how to goahead. As I was from different background this will help me to explore more into Data engineering role."

"The best part of this question bank that it explains the right and wrong answers in detail. This helps to validate the answers both right and wrong. It helps alot!"

"It was an eye open session with Rahul neekhra as i was unable to make decision in which role and path i should go . He guided me very well to choose the career path and technology i should focus . I strongly recommend his guidance if one need any guidance about role and technology. Even his course fees are very affordable to pay ."

"The hands-on exercises helped reinforce key concepts such as databases, schemas, warehouses, tables, and basic SQL. A great course for beginners as well as professionals looking to strengthen their Snowflake foundation"

"I had a great discussion with you about my skills and my transition into Data Engineering. He patiently reviewed my background, understood my goals, and provided clear, practical guidance on how to make the switch successfully. His advice was honest, insightful, and gave me a clear roadmap to start my Data Engineering journey with confidence. What impressed me the most was that he offered all this guidance completely free of cost, genuinely wanting to help. I truly appreciate his time, knowledge, and willingness to mentor others. I highly recommend connecting with him if you're looking for career guidance or planning a transition into Data Engineering."

"I had an amazing one to one call with Rahul. He provided me with all the points necessary before a major interview. His way of explaining the concepts is accurate and to the point. He listens to all the queries and promptly provides the solution for them."
