Hey friends - hope you have been taking lots of care ❤️
I’m not going to lie — I’ve spent a lot of this past week lying in bed Doomscrolling on Twitter. And then Facebook. And then YouTube. And honestly, even my email. Although my anxiety this past week has come from a lot of places, election anxiety has definitely played a huge part.
Reflecting on both my own election anxiety and this week’s topic of analytical interviews, I’ve realized they share a similar thread: they both seek to find clarity in ambiguity. The future after Tuesday, November 3rd is incredibly unclear and ambiguous, but I know for sure that one way we can find clarity in that ambiguity is to exercise our right to vote 🗳 (btw, if you’re registered to vote in the U.S. and you haven’t voted yet and plan to do so in-person, find your polling place here).
Similarly, when tackling a hefty estimation question like “Estimate the total number of videos on YouTube”, there is a lot of ambiguity. How many users/accounts does YouTube have, past and present? What percentage of those users create content and upload videos on YouTube? How often? In many ways, your job in tackling difficult analytical questions is to also find clarity in ambiguity. You could even use your estimation skills to answer “How many votes will be cast in the 2020 U.S. Presidential Election?” (if you do try this question out for fun, please share this with me! Would love to see it 🎉 )
This Tuesday, we will find clarity by casting our ballot at our local polling place, if we haven’t already. In your analytical interviews, you will find clarity by asking the right questions & planting a tree 🌳 (more on this below). Together, we’ll skillfully navigate ambiguity and find our path, whatever it may be.
LOL, I just noticed the last three sentences rhymed 😂. Anyways — here’s to bringing 👑 this energy 👑 to the polls on Tuesday.
If you want to chat more about finding clarity in ambiguity, or need a pep talk before that big upcoming interview, DM me on Twitter!

Since everyone is at different stages of the interview process, if you need an overview of all types of interviews, you can check out APM Map’s Roadmap to Recruiting 🚗 or the 180+ resources we have up on the APM Map directory.
💡 Mima’s Philosophy
Finding clarity in ambiguity. At the end of the day, analytical interview questions are trying to test for your ability to navigate ambiguity. Whether it be “Estimate how much it costs to run Gmail for a year” or “How would you measure success for FB Events”, these questions are designed to be unclear, so it’s your job to clarify them. Interviewers care less about the numbers you come up with and more about how clear and logical your thought process is. Which brings me to …
Root yourself with a tree 🌳 . As with every other Gen Z-er, ya girl is obsessed with plants 🌿 . Sadly, this tree is more of a decision tree, but once you land your dream job, you can buy yourself all the succulents and plants that your heart desires. Until then, check this out:
This sample picture that I pulled from here is exactly the type of tree I used when tackling estimation questions. It clarified my thinking process so much, and made the math a lot easier too. You can find more examples like this in Lewis Lin’s The Product Manager Interview! You can likely use a similar decision “tree” approach for your Execution interviews as well - more on those types of questions below.
📚 Featured Resources
Want to learn how to tackle Estimation questions?
For beginner/intermediate estimation questions, you can start by checking out Cracking the PM Interview’s chapter on Estimation questions.
If you’re looking for fact sheets, check out:
This Estimation Fact Sheet created by Soundarya Balasubramani, an awesome APM @ Salesforce
For more advanced Estimation questions, check out the estimation questions in The Product Manager Interview!
I did almost every single one of the Technical Estimation questions from this book, and it made me feel much more confident in my estimation skills.
I also LOVE the tree structure from this book. Once I started using the tree structure, it took my estimation interviews to the next level because it helped me organize my thinking from the getgo. Highly recommend!
Want to see a demo of how an Estimation question is done? I love this sample Estimation mock interview from Exponent, where a former Google APM tackles the “Estimate Pixel Phone Storage” question. If you’re new to technical estimation questions, this video is a great place to start.
Want to learn how to tackle Metrics / Execution / Diagnosis questions?
I didn’t do a lot of these questions in my interview loops last year because they weren’t relevant to the companies I interviewed with. So today, I’ll turn to some experts:
FB RPMs (Facebook is known to ask Execution questions)
Facebook RPM: From Prep to Offer by Jewel Lim
Facebook RPM Program Overview: Everything you Need to Know from Application to Interview by Parth Detroja
This mock Execution interview video with a Facebook PM from Rocketblocks
