This is a super common question, so here's a thread called What is the LeetCode for DS? that has 73 comments filled with resources you should check out! TL;DR - LeetCode is good for Software Engineers. DS folks may encounter those kinds of Data Structures + Algorithm questions in Python, but not really at the harder difficulty. MLE should prep for these though. For the prob/stat/SQL aspects of the interview, other better Data focused resources exist (my book Ace the Data Science Interview + DataLemur , a free SQL interview platform just being two things in a sea of resources you could explore) Answer from NickSinghTechCareers on reddit.com
