January 9, 2020What is the LeetCode for DS?
LeetCode for Python questions, easy gets you past coding rounds at most companies, DataLemur for SQL interview prep, Cracking the PM Interview is good for product data science questions and more open-ended business-y DS case problems. For ML interview questions, just knowing the most important concepts + terminology from Intro to Statistical Learning is good (most interviews ask about classical techniques, so don't worry if you aren't a deep learning pro). Practical Stats is good for Prob/Stat conceptual questions (but doesn't exactly map to what interviews test... unfortunately at FAANG + Wall Street you will find the occasional probability brain teaser).
You can also check out the book "Ace the Data Science Interview" on Amazon, which is like "Cracking the Coding Interview" but for Data Science & ML interviews. It covers all the topics mentioned above, but I'm a tad biased since I wrote the book!

r/leetcode on Reddit: Need Advice: Applied scientist Interview at Amazon
August 5, 2024 -
Hey everyone
After clearing the phone screen round, I got a call regarding the Applied Scientist virtual onsite round at Amazon.
It will probably be a 5 hour onsite (details are yet to be discussed with the recruiter). This sub has extensive information about the leetcode style questions but I wanted to ask the MLEs, Applied Scientist and Data Scientists on this sub as to what to expect in the ML depth and breadth round and Business application round. And how to prepare for each of these rounds? If you could share your some resources that would be helpful.
Also below are my leetcode stats, from here on I will focus mainly on Amazon but any other suggestions are appreciated.

Don’t Use LeetCode for Data Science Interviews: Here’s Why and What to Do Instead
October 1, 2025 - Data science interviews often feature case studies and open-ended problems that test your ability to: Extract insights from messy datasets. Build and interpret machine learning models. Solve business problems using data. LeetCode’s problems are typically clean-cut and lack the context-rich scenarios that reflect real-world data science tasks. While understanding algorithms is essential, data scientists are rarely expected to write complex algorithms from scratch.
