亚麻6月VO面经分享（含行为问题 + 面向对象设计题）

Q1: Tell me about a time you took on something outside your area of responsibility. （Positive问题）

这是一个关于主动性与“主人翁精神”（Ownership）的典型问题。你可以讲述一个你明明不需要做、但你发现问题并主动解决的故事。

Q2: How do you approach learning a new technology or unfamiliar domain? （Positive问题）

考察学习能力与“乐于学习与好奇心”（Learn and Be Curious）。可以分享你如何自学新框架、新工具，并快速应用到项目中。

Q3: Tell me about a time where no existing solution worked and you had to create your own. （Positive问题）

强调你的创新能力与“发明并简化”（Invent and Simplify）的精神。比如你如何规避现有限制、提出新思路并成功落地。

Q4: Describe a time you received constructive/critical feedback and how you handled it. （Negative问题）

考察“赢得信任”（Earn Trust）与抗压成长的能力。讲一个你起初不被认同，但最终通过沟通、反馈、改进赢得团队信任的例子。

Q5: Tell me about a time when you thought you wouldn’t meet a commitment.（Negative问题）

这是一个关于“结果导向”（Deliver Results）的压力测试题。你可以分享一个计划被打乱时如何调整资源或目标，最终还是交付的故事。

这一部分亚麻给的题都很和实际相关，我其实挺喜欢这样的题的。太抽象了不好理解。

面试题原文如下：

For most packages, the primary tasks we need to perform are picking up the package from some location and transporting it to its drop-off location. However, it’s possible that picking up the package fails—perhaps the driver couldn’t find the package. In that case, the package can no longer be dropped off. Let’s capture this in our Task and Route model.

Please:

1. Update your Task model to capture “Pickup” and “Drop-off” tasks for a package, and the relationship between them.
2. Update your Route to support marking the current task as failed/success.
3. Update your Route to skip over Tasks that cannot be executed during “getCurrentTask”, based on failures of their upstream tasks.
   • E.g. a failed pickup task should result in skipping over the drop-off task for the same package.

Assume that the list of tasks provided to you has all of the tasks that might be executed in the order in which they appear — if they aren’t cancelled.

Example Input Task List:

(pickup package a)
(pickup package b)
(drop-off package a)
(drop-off package b)

Simulation Output:

getCurrent -> pickup package a  
mark failure  
getCurrent -> pickup package b  
mark success  
getCurrent -> drop-off package b  
// note: drop-off package a is skipped

解题思路：

• 将 Task分为两类：PickupTask 和 DropoffTask，它们都与同一个 Package 实例相关联。
• 每个任务需要有 status状态字段，例如：PENDING、SUCCESS、FAILURE。
• Route 类负责维护一个任务列表 tasks[]，并追踪当前进行到哪个任务（可以用索引或队列）。
• 在 getCurrentTask() 中，如果任务是 drop-off 类型，但对应的 pickup 任务失败，就要自动跳过。
• 每次调用 completeCurrentTask(status) 后，推进到下一个可执行任务。
