面试建议：
Apple的这个经济学家/核心数据科学家职位是一个极具挑战性的角色，它要求候选人不仅具备扎实的统计学和计量经济学背景，还需要能够将这些技术应用到实际的商业问题中。这个职位最特殊的地方在于它需要候选人能够开发复杂的决策系统，并进行因果推断分析来评估新项目的影响。同时，双语沟通能力也是这个职位的重要考量因素，因为需要向非技术背景的合作伙伴解释分析结果。 为了准备这个面试，我建议你重点准备以下几个方面：首先，确保你对计量经济学模型有深入理解，特别是因果推断和时间序列分析。准备一些你过去应用这些技术解决实际商业问题的案例。其次，展示你的编程能力，特别是R/Python和SQL的使用经验。准备演示一些你开发的数据产品或者分析工具。最后，练习如何用简单明了的方式向非技术人员解释复杂的技术概念。记得准备中英文两种语言的表达，因为沟通能力是这个职位的重要评估标准。
