"💬 Dream job offer from  Apple!

Just wanted to share, I accepted an offer from Apple as a Data Engineer and wanted to offer a huge thank you to both of you guys.

Even though I only shared a small time with you both I benefited a lot from your platform and your mock interviews.

Some of the questions you gave during our Data Modeling with you Mike were presented verbatim.

Simply put, SQLPad is not the cheapest SQL interview prep site, but its high quality SQL interview questions makes it worth every penny. You can't practice anywhere else of such well thought and carefully designed business context oriented list of SQL coding questions.

I nailed my SQL interviews and received multiple Data Scientists offers that potentially double my currently salary, which makes the few hundreds dollars purchase of SQLPad lifetime bundle a steal.

I can always come back and use SQLPad when I want to prepare my next SQL interview.

💬 "I signed up on SQLPad and was pleasantly surprised when Leon helped me out personally on the website.

In two mock interviews with him from instamentor.com, he was meticulously prepared and very professional.

Throughout the interview he provided fantastic feedback and frameworks on how to be better prepared for both technical and behavioural aspects of an interview. He is also a very positive and friendly person and I enjoyed all my interactions with him.

Warm Regards,


"💬 SQLPad is the best website I have used for practicing SQL. The databases and practice problems resemble real-world data and daily tasks in a data scientist / data analyst role. I landed a new job as a data scientist at a tech company after completing all the practice problems. I would definitely recommend SQLPad to all who would like to improve their SQL skills and prepare for technical interviews."
