Convoy Data Scientist 面经。
shipment_id | shipper_id | date_time | pickup_state | dropoff_state
前两道都是基本的group by / where可以搞定。
- Deep dive into experiments design：
How to measure the test performance?
How long should a test last for / when to stop an experiment?
If a stakeholder wants to run some tests which you think may not be worthwhile, how do you deal with them?
- How to measure the success of a Referral program?
Follow-ups: is there any limitation on any of the metrics you mentioned
感觉公司挺看重culture fit和工作经验的，面试官不止一次的提到说“Convoy has a very complicated business”。公司节奏挺快，周六HR发来了OA，周一通知进入下一轮，周五电面，过了个周末就发据信了。很效率。
