Advanced Technical Product Manager Interview Questions Part 2
Design a technical roadmap for a new product feature
Can you walk me through your process for designing a technical roadmap for a new product feature?
Answer:
- Unpack the Problem: At Humana, when we built a predictive analytics tool for patient risk stratification, I began by interviewing clinicians and data teams to pinpoint gaps in existing tools—like real-time data latency issues. For a gaming feature at Aristocrat, I’d similarly engage game designers, developers, and players to define core needs (e.g., seamless cross-platform integration or latency reduction).
- Define Success Metrics: Collaborate with stakeholders to agree on goals. For Humana, it was reducing hospital readmissions by 15%; for gaming, maybe boosting player retention or in-game engagement.
- Break Down Requirements: Work with engineers to map technical dependencies. At Humana, this meant prioritizing APIs for EHR integration before refining the UI. For gaming, it might involve backend scalability for live multiplayer features.
- Sequence Deliverables: Use a framework like RICE to rank tasks by impact vs. effort. Prototype high-impact items first—like Humana’s MVP for real-time alerts—then iterate based on feedback.
- Build Flexibility: Roadmaps evolve. At Humana, we pivoted to include wearables data after early testing showed gaps. For gaming, I’d leave room for player feedback loops or emerging tech (e.g., AR/VR integrations).
- Communicate & Align: Share drafts with engineering, design, and execs via tools like Jira or Confluence, ensuring buy-in.
The key is balancing technical depth with agility—so the roadmap drives value without becoming a rigid checklist.
How do you prioritize technical requirements and allocate resources?
Before coming to Humana, I apply technical requirements first with a rigorous approach to reconcile business value, technical complexity, and resource limitation. I begin with stakeholders and identify their needs and expectations, and then I apply a weighted scoring matrix to evaluate each need across criteria such as revenue impact, customer satisfaction, technical interdependencies, and strategic alignment.
For instance, when I was over Humana’s patient portal project upgrade, we had conflicting demands for enhanced data security, reduced load times, and new functionality. I used a derivative of the MoSCoW approach (Must-have, Should-have, Could-have, Won’t-have) and combining story point estimation to develop a hard priority structure. This helped us discover that an addition of data encryption was an essential requirement that had to be addressed with haste, whereas some UI enhancements could be developed for upcoming sprints.
Resource allocation is defined by this prioritization through capacity planning meetings with engineering leads where I am involved in figuring out team capabilities and potential roadblocks. I have flexibility in our sprint planning to allow for unforeseen technical issues while keeping things on the critical path moving. This is something we did at Humana and were able to move 30% faster sprint velocity without compromising on deliverables quality. Where there are technical limitations, I broker a balance between business stakeholders and engineering teams to achieve practical solutions that balance technical debt management with feature delivery.
What metrics do you use to measure the success of a new feature?
To measure the success of a new feature, I track a mix of engagement, adoption, retention, and business impact metrics.
- Adoption Rate – Counts the proportion of users that begin to utilize the new feature out of the total users. High adoption rate signifies relevance and high first-time interest.
- Engagement Metrics – Monitors how the user is interacting with the feature (e.g., time spent, actions taken). If engagement levels are low, it could indicate that there are problems with usability.
- Retention & Stickiness – Sees whether users continue to utilize the feature in the long term (e.g., DAU/WAU or feature retention rate). If there is high drop-off, scope for improvement exists.
- Conversion Rate – When the feature is driven by revenue or lead, I track conversion rates to determine business impact.
- Customer Feedback & NPS – Qualitative insights of user feedback and Net Promoter Score (NPS) serve to make the feature more enriched and refined.
Optimize a slow-performing database query
Suppose you’re working on a project and you notice that a database query is taking an unusually long time to execute. How would you troubleshoot and optimize the query?
As a technical Product Manager, I would handle the problem of a slow running database query in a systematic and analytical fashion. To begin with, I would learn more about the query by looking at the SQL statement and the execution plan. It would include reviewing the query design, any possible bottlenecks or inefficient operations, and looking at the underlying data relationships and indexes.
Second, I would think about the size and complexity of the data being processed by the query. If the query is acting across a huge amount of data or complicated joins or subqueries, that may be contributing to the performance problem. I would then think about splitting the query into pieces that can be read more easily or looking at other solutions, like materialized views or denormalized storage.
In addition, I would be testing the server and database settings to determine if there are any hardware or software limits that are affecting query performance. This could include testing available memory, CPU usage, disk input/output, or even the indexing and partition strategies used by the database.
By methodically taking the query, data, and infrastructure apart, I would determine the cause of the performance problem and create a focused plan to optimize it. This may include updating indexes, rewriting queries, or even data model or application architectural changes.
What tools would you use to analyze the performance of the query?
When I need to figure out why a SQL query is slow, I usually hit it from a few angles. First off, I always look at the execution plan – you know, using tools in SSMS or similar platforms – because that tells you exactly where the query is spending its time. Then, I like to see what’s happening live, so I’d integrate with APM tools like New Relic or Datadog to get real-time data on latency and how much load it’s putting on resources. And if I need to go even deeper, maybe see how the query relates to system events or user actions, I’d pull up the logs using something like Splunk. Putting all that together really helps me zero in on the problem fast, see how different things are connected, and figure out the best way to make the query run better. This multi-tool approach is something I used a lot and found super effective back at Humana Inc., and I’m really excited to bring that experience and apply these methods here at Aristocrat Gaming.
How would you balance the need for query optimization with other business priorities?
My approach to balancing technical optimization, like queries, with business priorities, which I really solidified at Humana, is centered on value. At Aristocrat Gaming, performance is key, but it has to directly support our product goals and player experience – it’s never optimization for its own sake.
I evaluate the business impact of any optimization. Will making this query faster directly help us launch a key feature, improve a core user flow, or unlock new capabilities? We need to weigh that against other priorities, like delivering new features entirely. You wouldn’t necessarily hold up a major release just for a marginal performance gain.
Collaboration is huge here. I work closely with engineering, marketing, and other stakeholders to ensure our technical efforts are aligned with what matters most to the business right now. Understanding things like upcoming marketing pushes or critical reporting needs helps us prioritize where performance improvements are truly essential.
Ultimately, it’s about disciplined prioritization that ties back to Aristocrat’s overall strategy. We strive for technical efficiency, but it’s always in service of driving the business forward, fostering innovation, and staying competitive.
Technical Requirements Document (TRD) for a new feature
Can you create a Technical Requirements Document (TRD) for a new feature that involves integrating with a third-party API?
Sure, I can explain my process for putting together a Technical Requirements Document for API integrations. My experience at Humana, dealing with all sorts of data integrations, really taught me the importance of a structured approach, and I think it applies perfectly to gaming systems too.
I like to start with an ‘Overview’ section that’s really clear and to the point. It needs to spell out the purpose of the integration – like, why are we even doing this? What’s the scope? And what are the business results we expect? Maybe we’re syncing player profiles with rewards to offer personalized experiences and boost retention. That level of clarity upfront is essential.
Next, I move to the ‘System Architecture’. This is where we map out exactly how our system will communicate with the other API. We list the specific API endpoints involved, how we’ll authenticate securely (like using OAuth 2.0), and the data formats we’ll be exchanging (most likely JSON or XML). And, something you learn pretty quickly is you have to plan for failure, so this section also covers error handling procedures and how we’ll manage retries if calls don’t go through the first time.
Once the architecture is mapped out, we dive into the specifics. The ‘Data Requirements’ section is where we meticulously list every single piece of data being exchanged, its format, and any validation rules. Crucially, we figure out the mapping – how does our ‘Player ID’ connect to their ‘external_user_id’ in their system? We’ll note the specs, like ‘string, maximum 32 characters’. It’s all about preventing confusion later.
Then we hit ‘Security Requirements’, which I can’t stress enough is vital, especially in gaming with player data. We need to define our standards for encryption (like TLS 1.3), how we’ll prevent overload with rate limiting, how we’ll manage API keys securely, and ensure we have proper audit trails. This isn’t just best practice; it’s often required for compliance and building player trust.
‘Performance Requirements’ come next. This is where we set the expectations: how fast should the response be (ideally under 200ms?), how much traffic can it handle, and what’s our target uptime (maybe 99.9%)? We also outline how we’ll monitor it and what kind of alerts we need if performance dips.
And finally, we wrap it up with ‘Testing Requirements’. We document all the different tests we’ll do – unit tests, integration tests, and definitely load testing. This is super important in gaming to make sure the system holds up reliably when a ton of players are online, especially during peak hours. It gives us confidence that it’s solid.
