A*******y 发帖数: 18 | 1 请问他们现在还搞online Assessment 和Case study吗? Online assessment 包括数量
题吗?还是只有Behavioral 方面的? |
c***z 发帖数: 6348 | 2 Yes and yes.
But I doubt they review your answers...
One question I remember is given a set of words, tell which words are made
of same letters. The idea is to use hash table and check the collision lists
.
Bonus point is if you use bitarray to store the words, then no hashing is
needed. |
A*******y 发帖数: 18 | 3 大牛回答我的问题了,太感谢了。对你的为人和技术很崇拜。这数量和技术题有样题看
看吗? |
c***z 发帖数: 6348 | 4 Thanks for your kind words.
The other questions are insultingly simple, such as if the revenue is X, the
cost is Y, what is the profit...
The case study is to find most popular stores, given some SQL tables. |

Good luck! |
A*******y 发帖数: 18 | 6 再次感谢分享。
Hash表和bit array 不是算法里的吗?申请统计位置也考? |
c***z 发帖数: 6348 | 7 It was for a senior associate position. |

v******6 发帖数: 23 | 9 几个月前面的,还勉强记得些内容。。。
面试一共四部分,senior statistician role
1. Airplane delay case,请自行考古。不过注意下,面试的时候资料已经变成v1.1版
本了,所以在细节上(比如温度已经对晚点不影响了)跟帖子里写的稍有出处。最后问
了multicolinearity。还有就是如果你重建模,假设原有的glm没有问题,这个glm模型
该如何使用?
2. 考条件概率,内容是credit card delinquency risk。最后算出来的概率需要总结
出cutoff line需要往下挪(原有的假设95%的人都是good risk)
3. Behavioral questions. 就是你遇到过什么挑战啊,学习新知识啊。面试官拿了一
张纸,貌似他们用STAR (situation, task, action, results)的方式给你打分,所以
最好都讲到。
4. Americana (the Brazil Walmart) credit card case. 就是算revenue, fix cost,
variable cost和market share的。有空我把这个具体写一写 |

t****d 发帖数: 3204 | 13 看你面啥组
如果是credit risk那边的,model developer问的问题需要扎实的phd基本功。。。会
跟你聊论文
