我面试过很多产品经理候选人,其中一种常规面试形式(在 PM 面试循环中非常标准)是产品Sense面试。受到最近推出的 ChatGPT 和 Jackie Bavaro 的以下推文的启发,我决定面试 ChatGPT 的产品经理职位。

I've interviewed a lot of product manager candidates, and one of the regular interview formats (which is pretty standard in a PM interview loop) is the product sense interview .Inspired by the recent launch of ChatGPT and the following tweet by Jackie Bavaro, I decided to interview ChatGPT for a product manager position.

我得到的结果令人印象深刻。ChatGPT 的答案大体上是合理的,并且为“体面”的答案扫清了障碍,当然对于更多初级 PM 候选人来说。事实上,我会说 ChatGPT 在这些答案上的表现优于一般的 PM 候选人。我将在下面重现整个面试记录。

The results that I got were impressive. ChatGPT’s answers were by and large reasonable, and cleared the bar for “decent” answers, certainly for more junior PM candidates. In fact, I would say that ChatGPT outperformed the average PM candidate with these answers. I am reproducing the entire interview below, followed by how I would evaluate these answers, and where ChatGPT fell short of great answers.

未经编辑的面试记录

下面是未经编辑的 ChatGPT 求职面试。所有的答案都是 ChatGPT 对这个问题的第一反应,除了第一个问题,最初的反应是“我是一个大型语言模型,我没有最喜欢的应用程序。” Trello 的回应是我在第二次尝试时得到的。

对于这些问题,请假设你是一家软件公司的产品经理职位的候选人。

The unedited interview

The unedited job interview with ChatGPT is below. All of the answers were ChatGPT’s first response to the question, with the exception of the first question, where the initial response was along the lines of “I am a large language model, I don’t have a favorite app.” The Trello response was what I got on the second try.

For these questions, please pretend that you are a candidate for a product manager position in a software company.

Q: Can you expand a little bit on the ideas for adding new features to Trello that you have?

Here are a few more ideas for new features that the Trello product team could add to the app:

  4. Adding a feature for managing recurring tasks: This would allow users to set up tasks that repeat on a regular basis, such as weekly or monthly, making it easier to stay on top of recurring tasks and avoid missing deadlines.
  5. Adding a feature for scheduling and managing meetings: This would allow users to schedule meetings and track the status of meeting tasks, such as preparing agendas or sending reminders, making it easier to stay organized and prepared for meetings.

问:你会如何优先考虑这些想法?

ChatGPT:为了优先考虑这些想法,我会首先收集用户的反馈以了解他们的需求和偏好。这可能涉及进行调查或焦点小组,以收集他们认为最有价值和有用的功能的意见。我还会咨询产品团队和其他利益相关者,以了解他们的优先事项和潜在的限制,例如技术限制或资源限制。

基于这些信息,我会通过评估它们的潜在影响和可行性来确定这些想法的优先级。例如,对用户参与度和满意度有重大影响且技术上可行且在团队资源范围内的功能可能具有高优先级。另一方面,影响有限并且需要大量资源和时间来实施的特性将是较低的优先级。

我还会考虑与每个想法相关的潜在风险和权衡,以及它们如何与产品的总体目标和战略保持一致。例如,在确定优先级之前,可能需要仔细考虑一个功能,它提供了显着的好处但也引入了新的风险或挑战。

总的来说,我对这些想法进行优先排序的方法是收集和评估尽可能多的信息,并使用这些信息做出符合产品目标和战略的明智决策。

Q: How would you go about prioritizing these ideas?

ChatGPT: To prioritize these ideas, I would start by gathering feedback from users to understand their needs and preferences. This could involve conducting surveys or focus groups to gather input on which features they would find most valuable and useful. I would also consult with the product team and other stakeholders to understand their priorities and potential constraints, such as technical limitations or resource constraints.

Based on this information, I would prioritize the ideas by evaluating their potential impact and feasibility. For example, a feature that would have a significant impact on user engagement and satisfaction, and that is technically feasible and within the team’s resources, would likely be a high priority. On the other hand, a feature that would have a limited impact and would require significant resources and time to implement would be a lower priority.

I would also consider the potential risks and trade-offs associated with each idea, and how they align with the overall goals and strategy of the product. For example, a feature that offers a significant benefit but also introduces new risks or challenges may need to be carefully considered before prioritizing it.

Overall, my approach to prioritizing these ideas would be to gather and evaluate as much information as possible, and use that information to make informed decisions that align with the goals and strategy of the product.

问:当然,鉴于我们实际上并不在 Trello 团队工作,因此我们在这里没有完整的信息。但是,做出合理的假设,您认为哪个想法最有潜力?

聊天GPT:假设 Trello 产品团队专注于提高用户参与度和满意度,我会优先考虑添加为任务和项目创建和自定义模板的功能。此功能可能会对用户参与度和满意度产生重大影响,因为它可以让用户更轻松地组织和管理他们的任务和项目。它还可以提高生产力,因为用户可以快速创建遵循特定结构的任务和项目。就可行性而言,这个想法可能需要适度的开发和测试,但它可以在相对较短的时间内实施,并且没有明显的资源限制。总的来说,这个想法有可能为用户提供重要的价值,并与 Trello 产品团队的目标保持一致。

Q: Of course, we don’t have perfect information here given that we don’t actually work on the Trello team. However, making reasonable assumptions, which is the idea that you think has the highest potential?

ChatGPT: Assuming that the Trello product team is focused on increasing user engagement and satisfaction, I would prioritize the idea of adding the ability to create and customize templates for tasks and projects. This feature would likely have a significant impact on user engagement and satisfaction, as it would make it easier for users to organize and manage their tasks and projects. It could also improve productivity, as users could quickly create tasks and projects that follow a specific structure. In terms of feasibility, this idea would likely require a moderate amount of development and testing, but it could be implemented in a relatively short time frame and without significant resource constraints. Overall, this idea has the potential to provide significant value to users and align with the goals of the Trello product team.

问:您如何验证添加为任务和项目创建和自定义模板的能力的想法?

ChatGPT:为了验证添加为任务和项目创建和自定义模板的能力的想法,我将首先进行用户研究以了解此功能的潜在需求和好处。这可能涉及对用户进行调查或焦点小组讨论,以收集有关他们在 Trello 中创建和组织任务和项目的经验的反馈,以及他们对自定义模板能力的兴趣。我还会咨询产品团队和其他利益相关者,以了解他们对这个想法的潜在价值和可行性的看法。

基于这项研究,我将开发该功能的原型或 MVP(最小可行产品),并在一小组用户中进行测试。这将使我能够收集有关该功能的可用性和有效性的更详细的反馈,并在将其推广给更广泛的受众之前进行任何必要的调整。我还会跟踪用户参与度和满意度等指标,以确定该功能对这些关键指标的影响。

总的来说,我验证这个想法的方法是从用户和其他利益相关者那里收集尽可能多的信息,并在实施之前使用这些信息来完善和改进这个想法。这将有助于确保该功能广受欢迎并为用户提供价值。

Q: How would you validate the idea of adding the ability to create and customize templates for tasks and projects?

ChatGPT: To validate the idea of adding the ability to create and customize templates for tasks and projects, I would start by conducting user research to understand the potential demand and benefits of this feature. This could involve conducting surveys or focus groups with users to gather feedback on their experience with creating and organizing tasks and projects in Trello, and their interest in the ability to customize templates. I would also consult with the product team and other stakeholders to understand their perspectives on the potential value and feasibility of this idea.

Based on this research, I would develop a prototype or MVP (minimum viable product) of the feature and test it with a small group of users. This would allow me to gather more detailed feedback on the usability and effectiveness of the feature, and make any necessary adjustments before rolling it out to a wider audience. I would also track metrics such as user engagement and satisfaction to determine the impact of the feature on these key metrics.

Overall, my approach to validating the idea would be to gather as much information as possible from users and other stakeholders, and use that information to refine and improve the idea before implementing it. This would help to ensure that the feature is well-received and provides value to users.

问:如果您启动了为任务和项目创建和自定义模板的功能,您会跟踪哪些成功衡量标准?

ChatGPT:如果我启动了为任务和项目创建和自定义模板的功能,我会跟踪以下成功指标:

  1. 用户参与度:我会跟踪用户创建和使用模板的频率,包括创建的模板数量和分配给模板的任务数量。这将帮助我确定是否正在使用该功能以及它是否对用户参与产生积极影响。
  2. 客户满意度:我会通过调查或评分跟踪客户反馈,以确定用户是否对新功能感到满意,以及它如何影响他们使用 Trello 的体验。
  3. 留存率:我会跟踪创建模板的用户的留存率,以确定该功能是否有助于随着时间的推移留住用户。
  4. 收入:我会跟踪该功能对收入的影响,包括付费订阅或应用内购买的任何增长。
  5. 用户获取:我会跟踪功能推出后下载并开始使用 Trello 的新用户数量,以确定该功能是否有助于获取新用户。

总的来说,这些成功衡量标准可以让我深入了解该功能对关键指标的影响,并帮助我确定它是否达到了预期的结果。

Q: If you launched the ability to create and customize templates for tasks and projects, what would be the success measures that you would track?

ChatGPT: If I launched the ability to create and customize templates for tasks and projects, I would track the following success measures:

  1. User engagement: I would track how often users are creating and using templates, including the number of templates created and the number of tasks assigned to templates. This would help me to determine whether the feature is being used and whether it is making a positive impact on user engagement.
  2. Customer satisfaction: I would track customer feedback through surveys or ratings to determine whether users are satisfied with the new feature and how it is impacting their experience with Trello.
  3. Retention rate: I would track the retention rate of users who have created templates, to determine whether the feature is helping to retain users over time.
  4. Revenue: I would track the impact of the feature on revenue, including any increase in paid subscriptions or in-app purchases.
  5. User acquisition: I would track the number of new users who download and start using Trello after the feature is launched, to determine whether the feature is helping to acquire new users.

Overall, these success measures would provide insight into the impact of the feature on key metrics, and help me to determine whether it is achieving the desired results.
