About this package

Knowing an answer and explaining why it works are two different skills. I created this package to help you practise both.

Hey, I’m Ajay Kadiyala. This bundle brings together my Data Engineering Interview Kit, hands-on SQL + PySpark labs, and one focused written response from me.

Here’s what you get:

📘 Complete Interview Kit — 25 Documents

Use my existing interview-preparation material to organise your revision, work through questions, and identify topics you need to revisit.

💻 SQL + PySpark Practice Lab

Work through five business scenarios in both Spark SQL and PySpark:

• Deduplicate order updates.

• Calculate customer revenue after refunds.

• Find consecutive login streaks.

• Process late-arriving sales and check safe reruns.

• Reconcile source and target tables.

The lab pack includes five practice notebooks, five solution notebooks, synthetic datasets, expected outputs, automated checks, explanations, follow-up questions, scoring rubrics, and a START_HERE guide.

Write your answer, run the checks, inspect the results, and compare your reasoning with the solution.

💬 One Personalised Written Answer from Ajay

Use the included Ask Ajay service for one focused question about your data engineering preparation, learning priorities, or interview approach.

Share your background, goal, and one clear question so I can give you a useful response.

This includes one written answer. Live calls, full resume reviews, complete code reviews, and ongoing mentoring are not included.

Who is this for?

Learners with basic SQL and Python knowledge who want structured interview preparation and practical coding exercises.

What do you need?

A laptop or desktop and either a compatible Databricks Python notebook environment or local Spark. The guide explains setup. The SQL exercises use Spark SQL.

How I suggest you use it:

  1. Choose a topic from the interview kit.
  2. Attempt one lab in your stronger language.
  3. Check the output and explain your decisions.
  4. Review the solution, then try the other language.
  5. Use your Ask Ajay question for a specific preparation doubt.

Learn at your own pace. Focus on understanding one problem properly before moving to the next.

This is a self-study package with one written Q&A. It does not include certification, job placement, or guaranteed interview results.

I recently had a one on one mentorship session with Ajay Kadiyala, and it was a very valuable experience for me as a data engineer with 7 years of experience. Although I had already started upskilling, I was doing it in an unstructured way, using random resources without being sure if I was on the right track. Ajay helped me bring clarity and direction to my learning journey. He provided a clear, step by step roadmap and guided me on the key fundamentals and topics I should focus on for real world data engineering roles and end to end projects. This gave me much needed confidence and focus. He also suggested useful resources for practice and shared practical advice on improving my resume to align with ATS standards. What stood out was his continued support. He offered to review my resume after I update it and also help me prepare through mock interviews. Overall, this session helped me move from a scattered approach to a clear and structured plan. I would highly recommend Ajay to anyone looking to grow in the data engineering field.

Huge thanks to Ajay for the fantastic session! He took the time to listen to all my questions and gave me clear, "pin-point" advice on my resume and data engineering path. It is rare to find someone with both deep technical skills and the patience to mentor others so effectively. Special thanks for crafting the interview prep kit for Data Engineers! If you are looking for guidance in this field, I can’t recommend him enough. Thanks again, Ajay!

What impressed me most about Ajay is his genuine willingness to help others succeed. Despite his busy schedule as a Lead Data Engineer and his extensive community engagement, he made time to ensure I had clarity on the fundamentals and a clear path forward in my career. Ajay’s mentorship has given me both the knowledge and confidence to progress in data engineering.
