Product Manager Data Interview Skills & Questions
A brief guide for winning your analytical job interviews
Sessions are down 20% today - why?
I’m - currently working on Product, Data and Growth at Coda, previously startup Founder/CEO, and before that a PM at Google and YouTube. I’ve been both the interviewer and interviewee for product analytics questions countless times. This is the first time I’ve shared my playbook. , and !
You’re interviewing for your dream job as a at Unicorn, Inc. You’ve researched the company, used their new product, know the product vision and all the product features, familiarized yourself with stakeholders, the engineering team, their product design language, and product strategy. You even know how they do product development and have your list of ideas for new features and functionalities they could include in the product roadmap.
But you didn’t see these data questions coming and don’t know where to begin.
Why didn’t you click on that link “How to Ace Your PM Data Interviews” you saw scrolling through your feed the other day? Just kidding! Let’s dive in. 👊
How to read this doc
My hope is that after reading this post you have an interview prep cheat sheet for how to answer common analytics interview questions and you have some easy next steps to get even better prepared and potentially land that product manager job.
This page focuses on high-level context and strategy in the interview process. We’ll walk through the kinds of questions product manager candidates may be asked, each of which have deep dives on their own pages. We’ll break down what interviewers are looking for and in the following pages, we’ll dig into detailed sample PM interview questions, with examples of strong and weak answers at each step.
The meat of this is post in the detailed walkthroughs: , , and . There’s also an extensive bank of and additional .

While we’ll focus on Product Manager interview questions, in practice these same kinds of questions often show up for Software Engineers, Marketers, Data Analysts, and other roles.
What product manager interviewers are really looking for
Keep in mind interviews are more about understanding how you think than getting the “right answer.” Candidates often make the mistake of getting caught up trying to get to the “right solution” and skip explaining their reasoning. PM interviews are as much about the why of your solution, as they are about the how — communicating your reasoning is the main thing an interviewer is trying to assess in the interviews. So it’s much better to have amazing reasoning but not fully get to a final answer than an answer that’s hard to contextualize or reason about.
Project manager interview skills cheat sheet
Here’s a list of key skills, how to demonstrate them, and the common pitfalls faced by even the best project managers in the field.
Skill
Demonstration
Common pitfall
💭 Structured thinking
Uses a framework to solve a problem methodically. Articulates and rejects hypotheses. States assumptions explicitly, and what could change them. Communicates goals that drive decisions.
Jumps straight into details without setting any context. Assumes something unstated and incorrect about the setup.
🤔 Asks good questions
Asks questions that bisect the solution space and give the most information on what to do next. For more on what this looks like, check out .
Overly focused on the wrong details. Asks lots of small clarifying questions when clearly trying to buy time to think.
🦅 Changes altitudes
Able to go from high level abstractions to nitty gritty details. Able to talk about different user segments and how behaviors and characteristics vary across them.
Jump to an answer but miss the chain of reasoning on how you got there.
📓 Demonstrates experience
Shows expertise by connecting answers back to specific personal experiences. Demonstrates familiarity with terminology, methodology, and best practices. Note this skill is called “demonstrates experience” rather than “has experience”: it’s not enough to have relevant knowledge, you have to show it and connect it effectively.
Speaks in generalizations without giving specific examples from own experience.
💬 Communication
Good communication skills. Takes time to think when needed, signposting thinking, asks questions, isn’t defensive when challenged, reads when the interviewer is giving hints.
Feels obligated to start talking immediately and just starts talking, clearly stalling for time.

Back when I was at Google, most interviews were scored on a 5 point system (1 being poor and 5 being strong). Here at Coda, we use a 4 point system - which is much clearer: you cannot do OK. As an interviewer, if I’m on the fence, that rounds down to a no.
1 - strong no 😡
2 - no 🙁
3 - yes 🙂
4 - strong yes 😍
Three types of product manager data interview questions
There are three main types of data interview questions. We’ll break each down in detail in the following pages.
Dig into a change in metrics to uncover why it changed.
Decide what metric a product should optimize for and why.
Identify, compare or use growth levers for a feature or product.
Note these types of questions go by many different names at different companies. For example, Facebook has a mix of these under an Execution Interview header, Thumbtack calls these Analytical Interviews, and here at Coda, we have a Marketecture Interview. The reality is these questions types aren’t as discrete as I outline here but exist on a spectrum. That said, I’ve found these three types useful as “corners of the tent” to show a range of problem-solving formats, with the more common case somewhere in the middle.
Three simple steps to frame your answers
Here’s my simple framework to use on all of these questions:

Here are some potential questions you might get asked during your product manager data interview:
Question type
The arc of this question
Step 1: set context. Clarify your understanding. Ask follow-up questions to better diagnose what is going on.
Step 2: go broad. Through the process of digging in, articulate a range of hypotheses. Describe the key data points for verifying what is going on.
Step 3: converge. Settle on one hypothesis and flesh it out with more detail. Propose a few solutions given the hypothesis, and select and justify one for execution. Discuss how you'd measure that your solution is working.
Step 1: set context. Describe the highest level mission and business goal of the product. You'll derive your goal setting metrics from this. Discuss your different user types and which are core vs growth areas.
Step 2: go broad. Propose a few candidate high level metrics that could illustrate progress towards the mission. Discuss flaws and pros/cons with each metric, and ways to mitigate the downsides.
Step 3: converge. Select the final choice of key metric, and describe a process and secondary metrics that you could use to prevent "overfitting" to the metric.
Step 1: set context. State your product mission, business goal, and highest level metric. Describe who your product's different user types are and why they use the product today.
Step 2: go broad. Return to the growth question and propose a few different approaches, and discuss pros and cons.
Step 3: converge. Select one of your approaches. Describe mitigating factors and learnings or new information that could change your approach.

It’s worth calling out that having a good framework for your answer is necessary but not enough by itself. There’s a common type of poor interviewee who is overly focused on a high-level framework, and fails to engage in the gritty detailed discussion and trade-offs of concrete options and ideas. Don’t be “just a framework person” - make sure you continue to connect it back to the details.
If it sounds too simple and easy, you’re half right. It is simple, but it’s not easy. Like most things, it comes down to how you do it. The best way to do it well is to practice. 👇
Practice makes perfect
Interviewing is a skill that, like all skills, you get better at the more you do it. One of the best ways to practice is to go through sample questions with friends or colleagues and have them give you feedback. Getting more examples under your belt always helps. In that spirit, we’ll walk through example questions together and analyze a range of different sample answers. Or you can skip ahead to the .
