Testimonials
"I signed up for the DataLemur Beta in July when a post about it randomly came up on my LinkedIn feed. I’m so glad I came to know about DataLemur because a few months later when I interviewed at Amazon, not one but TWO of the SQL problems from DataLemur showed up during my onsite interview which I was easily able to ace!"
— Jia Z. 
"In Fall 2021 I used the book Ace the Data Science Interview to land a Product Data Science job at Meta. As I prep to switch jobs in early 2023, DataLemur is proving itself very handy because it allows me to interactively practice many of the SQL questions from the book, but also has tons of new Stats & ML interview questions that aren’t in the book"
— Rakesh 
"I did Udemy SQL courses but they didn’t have enough interview practice which is why my NIT batchmate told me to try DataLemur. Using the detailed hints and nice solutions on DataLemur I was able to crack interviews at Infosys and Accenture and get ₹4 lakh salary increase"

About DataLemur Founder Nick Singh
Hi, I’m Nick Singh! Before I made DataLemur, I used to write SQL queries and run A/B tests all day at Facebook, and before that, wrote Python on Google Nest's Data Infrastructure Team. I know first-hand how difficult Data Science, Data Analyst, & Data Engineering interviews can be.
While my best-selling book, Ace the Data Science Interview, has successfully helped 16,000+ readers prepare for the Statistics, ML, and Business-Sense portions of data interviews, readers kept asking for a more interactive way to practice the 201 questions from the book.
That's why I made DataLemur, an interactive SQL & Analytics interview platform for the data community!
