大概一周后收到邮件说是约时间做一个2h take home challenge,还有15min grace time.在地里看面经,没找到,做完了来贡献一下题目。
这是他们的要求:. ----
• The case study will be delivered via e-mail as attachments at the pre-arranged time, and yo会不会对最后结果有影响。
题目发下来感觉我自己做的有点紧,出于保密没办法把具体的东西发上来,只能说一下大概题型。他们给的数据库是真实数据的一部分,注意不保证数据是clean的,然后我抽到的题目是预测一个continuous value,他有8道题,前面1-4题基本上就是筛选出符合要求的数据,画指定的图,不难,但是要求对自己使用语言的包掌握的比较熟练,我很久没怎么用python library做数据清理了,有的东西还是有点生疏了,这些常用的技巧还是要整理出来。他们会让你drop variable/data,要说出理由,然后第六题是build linear regression,evaluate metric,第七题是自己选模型,第八题就是两者比较,说出你认为优劣的原因。第九题我觉得很tricky,他说你会怎么把这个模型用在business setting下,我当时没什么时间了,只能尽可能的往business上扯。如果有更好的思路欢迎交流! |
