During a PM interview, one frequently posed and challenging inquiry is: “How would you define success for this product?” This question evaluates your capacity to think both strategically and quantitatively regarding product effectiveness.
Interviewers aim to gauge how you define, measure, and analyze metrics that are vital to a product’s success. Your response reflects not only your comprehension of the product but also your ability to harmonize it with the company’s objectives.
Product Managers must be adept at defining success metrics, as they will oversee features and bear the responsibility for determining the goals and metrics associated with those features.

Approaching the Success Metrics Inquiry
When confronted with a question about success metrics during an interview, a methodical approach can be extremely beneficial. Follow these steps to navigate through such inquiries:
Clarify the Question
Begin by ensuring you fully grasp the question. Don’t hesitate to ask for clarification if necessary. This demonstrates your attention to detail and eagerness to engage thoroughly with the issue, aligning both parties on the same understanding.
Define the Product, Target Users, and Value Proposition
Offer a concise yet thorough overview of the product, its intended users, and the value it delivers. This context sets the groundwork for discussing metrics.
Identify Core Metrics/North Star Metric
The North Star Metric serves as the principal indicator of the product’s success, aligning with its core value proposition and long-term vision. For a social media platform, this could be metrics like "daily active users" or "average time spent on the app."
Derive North Star Metrics Using a Metrics Tree
Decompose the North Star Metric through a Metrics Tree, identifying sub-metrics that influence it directly. For instance, if "user engagement" is the North Star Metric, sub-metrics might include "number of posts per user" or "average session duration." This breakdown aids in pinpointing actions that can favorably impact the North Star Metric.
Discuss Counter Metrics
Counter-metrics are crucial to ensure that the pursuit of the North Star Metric doesn’t lead to adverse consequences. For example, boosting user engagement should not compromise user privacy or satisfaction. Counter-metrics maintain a balanced growth strategy.

Problem Statement: Imagine you are a Product Manager for YouTube Shorts; what success metrics would you define or look for? How would you define success?
Candidate: Alright, we are discussing YouTube, which encompasses various products like YouTube Music and YouTube Shorts. Are we focusing on a specific product here?
Interviewer: Let’s concentrate on YouTube Shorts for this discussion.
Candidate: YouTube Shorts is available in multiple countries; are we evaluating a specific country or region for the metrics?
Interviewer: Globally.
Candidate: Okay, may I take a moment to gather my thoughts?
Interviewer: Of course.
Candidate: Here’s how I would approach breaking down the problem statement and determining the appropriate success metrics:
- Understand the company and its mission.
- Comprehend the product.
- Identify core metrics.
- Determine North Star metrics.
- Recognize counter metrics.
Does that sound appropriate?
Interviewer: Yes, please proceed.
Candidate: YouTube’s mission is to empower everyone with a voice and showcase the world. This mission applies to YouTube Shorts as well.
YouTube is one of the largest video platforms globally and serves as the second-largest search engine, holding a significant market share in video viewership.
However, with the emergence of TikTok, a new player capturing considerable market share, YouTube identified an opportunity and launched YouTube Shorts to compete directly.
Let’s examine the product's current position in its lifecycle.
Based on the four stages of the product lifecycle:
Currently, YouTube Shorts is in the growth phase of its lifecycle.
Interviewer: Why is it important to know the stage of the product lifecycle?
Candidate: Understanding the lifecycle stage informs the metrics the company should prioritize. In the growth phase, the emphasis is often on adoption and acquisition rather than revenue or engagement.
Does that sound reasonable?
Interviewer: Yes, please continue.
Candidate: Now that we comprehend the product's mission and lifecycle stage, let’s analyze the various users and the value proposition.
YouTube Shorts caters to a short-form video audience, focusing on vertical videos under 60 seconds, appealing to users who enjoy scrolling through concise content.
The unique selling proposition of YouTube lies in its personalized and seamless viewing experience, coupled with high-quality content.
YouTube Shorts serves three main user groups: viewers, content creators, and advertisers.
Creators can connect with a wider audience, while viewers can discover engaging content tailored to their preferences.
Do these assumptions resonate?
Interviewer: Yes, please proceed.
Candidate: Now that we have established an understanding of the product, let’s define the success metrics or North Star metrics that will help gauge the overall success or failure of the product.
A North Star metric signifies the value delivered to all user segments—viewers, content creators, and advertisers.
The aggregate time spent watching Shorts can be utilized to assess user satisfaction with content recommendations, indicating for creators that their content is being appreciated and providing advertisers opportunities to engage their target demographics.
Based on this analysis, I propose the following North Star Metric:
NS: Average time spent viewing Shorts per day.
Does that seem appropriate?
Interviewer: Why did you select a daily measure?
Candidate: I believe a daily metric is most suitable, as weekly or monthly evaluations may delay necessary insights, while hourly metrics should be treated as secondary and only examined if daily metrics display fluctuations.
Interviewer: Could daily evaluations lead to inaccuracies?
Candidate: No, given the rapid changes in user behavior, especially with video content, monitoring daily metrics is essential to avoid missing significant shifts.
Interviewer: What factors could influence your success metrics?
Candidate: To pinpoint what might affect the success metrics, we need to dissect them.
Average time spent viewing Shorts per day = # of users on the platform (Shorts) * Avg time spent per user = (# of free users + # of premium users) * Avg time spent/user
Avg Time spent/user = (Avg time/session) * (# of sessions)
Thus, changes in the following metrics can impact our success metrics:
- # of free users
- # of premium users
- Avg time/session
- # of sessions
To ensure positive success metrics, these elements must show favorable trends.
Interviewer: Are there additional metrics you would track?
Candidate: The Average time spent viewing Shorts per day will be my primary success metric. Other metrics I would monitor include:
- Average time spent/user/day
- Daily Active Users (DAU)
- Average likes on Shorts/day
- Average comments on Shorts/day
- Number of new Shorts added/day
- Number of Shorts shared/day
These supplementary metrics would complement my primary success metric.
Interviewer: Anything else?
Candidate: In addition to success and supporting metrics, I would track counter metrics.
There’s a possibility that success metrics might be misleading. For instance, a decrease in Shorts played alongside an increase in daily users may not be accurately reflected in the success metrics.
To counter this, I will track the following counter metrics:
- # of Shorts played/day
- Average time spent/Short/day
- Average number of Shorts viewed/user/day
These counter-metrics will help ensure we remain on the right track.
Interviewer: That was a thorough breakdown and explanation.
