最近咱们又有一位小伙伴收到了 DoorDash 的 Machine Learning Engineer Intern 面试邀请，真的非常优秀。DD 家的 ML 岗面试一向是以注重落地和硬核技术出名的，这波喜讯确实振奋人心。

关于面试流程，通常会先安排一轮 Recruiter Screen 简单同步下背景，随后就是高难度的 Technical Interview。面试官会考察 Coding 能力和 ML 基础理论，比如常见的 Loss Function 或者是 Bias-Variance Tradeoff。最关键的还是 Virtual Onsite 里的 ML System Design，DD 非常看重你能不能解决实际的业务问题，比如如何优化配送路径或者做餐厅的 Ranking 推荐。

面试真题方面，大家可以多关注 LeetCode 上的典型算法题。对于 ML 专项，可能会问到如何处理 Data Imbalance，或者是在特定延迟要求下如何部署模型。建议大家把 DD 的工程博客多翻几遍，了解他们的业务逻辑。

祝愿大家在求职季都能顺利通关，早日拿到心仪的 Offer~
