Amazon亚麻电面 面经
data scientist 的岗位 .--
三个部分,先go through resume,14leadership principals,然后stat&ML,最后coding(Python),Q&A
1.lp:tell me a time that has a goal that is hard to achieve?what do you learn from that? (hr和我说是考deliver results)
2.resume:关于resume 的project 很详细的问,遇到什么问题,data是啥样的,怎么解决的,最后结果如何
3.stat & ML:我以为会问ds的问题,结果问的都是a/b testing,causal inference,two sample test, how to decide the time period of the test(没啥abtest 的经验,所以特别懵——)
4.coding(Python):word count 给你一个string 是一句话,然后 count每一个词出现的次数,写个function,然后如果有大小写咋办,如果有标点符号咋办. From 1point 3acres bbs
5.Q&A
