【化学转ds】Facebook ds偏data analystics面经,求大米!求大米!求大米! ============================================================================================================================ . 1point 3acres
帖子贴的有点晚,但题目绝对新鲜。之前我在地里都没有见过原题,所以我会给大家写的比较详细,希望能对地里的战友有所帮助。首先感谢bastenshk的强推,我才有了facebook的面试机会。以下是他在地里的帖子: https://www.1point3acres.com/bbs/forum.php?mod=viewthread&tid=441177&extra=page%3D1%26filter%3Dsortid%26sortid%3D192%26sortid%3D192
我本人是化学转ds,之前申请ds的工作屡屡碰壁,经过摸索发现申请关于data analyst方向的ds面试机会比较大,因为以前化学专业也都是通过数据分析得到的结论,所以简历什么的都可以往数据分析上面扯。这个是给转专业的同学的一点建议。Facebook我申的同样是data analyst方向的data scientist,不涉及到machine learning。

第一轮Recruiter
因为是内推的原因,recruiter也没问太多的东西。就是常见的why facebook,self intro,talk about your experience。如果Recruiter人很nice,跟她聊聊天,说一下自己喜欢湾区什么的,最后recruiter简单介绍一下这个职位,直接说进入下一轮tech interview,考察sql和case study。Recruiter会让你选择用python还是sql,我选了sql 。接着她会发信跟你讲一下how to prepare interview和定时间之类的
第二轮 tech interview (很有意思,但是是挂掉了) . ----
面我的是product manager,上来问我有没有用过 Facebook marketplace? 我说没有,他楞了几秒,然后给我介绍了他们自家的产品,是一个类似craigslist的产品,人们通过facebook来发布local的广告和通过facebook messeng /div>
Q6. What is the benefit of launching Call to action (e.g., learn more, buy)? What metrics used for measure the effect? Want to sell? Goal is to encourage people to sell products Metrics: # of users who sell their products # Conversion rate (# people clicked yes/# people viewed) # Monthly/daily active users # Engagement/Time spent on browsing marketplace
. Waral dи,Q7. The message_sent/session drops 10% month by month. What is the reason? Replied Seasonality effect (look at historical data), time span(two months data vs. six months data), maybe buyer will not use facebook messenger to leave a note to buyers, competitors, does they show similar trend? In the end, the interviewer mentioned it is mainly because area effects, some regions drops, while some regions increases. Need further investigation on this problem. [\hide] 总体感觉facebook比较关心你对于他们产品的了解程度。如果你有过IT公司从业经验或者对他们产品有所了解的话过的机会应该是蛮大的。但是有一点大家要注意,facebook面试比较一板一眼,他们会问些有标准答案的问题,不像google问的都是些open ended questions。所以我在回答问题的时候,如果我回答的东西不能让interviewer满意,他们会问next?next?next?这种情况应该是你没有说到点子上。如果你能多刷点题目,加上well prepared,拿到offer应该是没有问题。 祝大家好运!拿offer拿到手软! .
