最近在准备面试，发现case study很难准备，想买一套这个资料看一下，有没有mm想一起合买呀。 一共是三个部分$299 1. DS takehome challenges: 20 take-home challenges with real world data sets. 4 challenges have detailed solutions with reusable step by step code in Python and R. See here for challenge samples 2. DS product questions with answers: A subset of just 40 among all the product questions included in the full course. These 40 questions are introductory and more high-level, while the additional ones in the full course are harder and more applied 3. 6 SQL problems with solutions modeled after top tech company SQL shared screen interview step 这是网站链接：https://datamasked.com/

谢谢mm发的这个链接， 第一部分我也已经开始做了， 我现在最想看的是那40道 DS product questions with answers。 这个在网上搜不到。
灌水的地方都是ds内卷
我觉得take home challenge确实不太需要买， 就是那个40道题的product sense的题比较有用，但他又不分开卖。
