Example: The most interesting data science project I’ve done last year was a project that aimed at improving the customer retention by delivering a new feature on our app. The new feature was to provide predictions of the estimated time of arrival for shipments. It was a six month project and we were able to improve customer retention by 50%.
3. Challenges
给出以上概述后,最好跟面试官确认下,比如可以问do you want me to provide more context or dive into the details of the project? 这种对话的形式可以使面试官更有参与感。
Were there problems when defining success metrics?
Was it difficult to obtain the data?
Is the size of data large, if so, how did you deal with a big dataset?
Did the data have high quality, how did you process the data?
Was there any challenge in model training and deployment?
Non-technical challenges 例子:
If it's a project involving multiple teams, did you get any objection from other teams?
How did you get other people to buy into your idea?
Was there any risk in delivering the project on time?
What have you done to unblock yourself, your team or other teams?

4. Interesting findings
讲完challenges,可以继续跟面试官互动,比如do you want to hear more details about it, shall I move forward to describing the project?-baidu 1point3acres
如果还有时间,可以说一个interesting finding,这样面试官会觉得我们不仅能deliver project,而且还享受做项目的过程,并注意到一些常人会忽略的细节。
