Twilio Product Manager (PM) Interview Guide

Learn how to prepare for the Twilio Product Manager interview and get a job at Twilio with this in-depth guide.

Interested in becoming a "Twilion"? If you're using voice, text, chat, video, and/or email tools to communicate with businesses, chances are you've used Twilio. Twilio's APIs make it easy for businesses to connect with customers in many secure and effective ways.

The company, which went public in 2016, has grown immensely and now owns a respectable portfolio of messaging providers, IoT providers, and the like. Generally loved by developers, it's also been supportive of the open-source movement. It launched an open-source messaging product as early as 2010, and the list of contributable projects has only grown.

Twilio's company values (sometimes referred to as "magic values") are as follows:

  • Be an owner: Owners know their business, embracing the good news and the bad. Owners sweat the details and “pick up the trash.” Owners think longterm, and spend money wisely.
  • Empower others: We believe that unleashing human potential — both inside and outside our company — is the key to our success. Be humble and realize it’s not just about us. Invest in each other.
  • No shenanigans: Always act in an honest, direct, and transparent way.
  • Wear the customer's shoes: Spend the time to deeply understand customers, and solve problems from their perspective. Earn trust through every interaction.
  • Write it down: Our business is complex, so take the time to express yourself in prose — for your sake, and for the folks with whom you’re collaborating.
  • Ruthlessly prioritize: Prioritization helps break down complex problems, and provides clarity in the face of uncertainty. Decisions are progress, so make decisions with available information and keep learning.
  • Be bold: We’re driven by a hunger to build a meaningful and impactful company. Embrace crazy ideas and remember, every big idea starts small.
  • Be inclusive: To achieve our goals, we need a diverse set of voices in the room. Build diverse teams, and seek out unique points of view.
  • Draw the owl: There’s no instruction book, it’s ours to write. Figure it out, ship it, and iterate. Invent the future, but don’t wing it.
  • Don't settle: Expect the best from yourself and others, because there’s no feeling greater than being proud of our work. Hire the best people for every role.

Sound like a good place to work? Many agree! Before you begin your prep, be sure to read our guide on Twilio PM interviewing. The loop has been called grueling, but it's not terribly more difficult than high-growth tech companies. That said, practice makes perfect. We'll examine frequently asked questions about the Twilio interview process, including hiring criteria and tips to succeed in the interview.

Interview Process

First, you'll make contact with a recruiter. Twilio recruiters use many platforms and techniques to source candidates - some interviewees reported being invited to webinars explaining the R&D process, others are messaged directly via email or on LinkedIn.

Next, you will have a short (~15 minute) screening call. This call is meant to prove that you are who you say you are - that is, that you haven't entirely inflated your resume. You'll review the highlights of your past experience, and your recruiter will explain Twilio's mission, any pertinent info on the specific team, and the next bit of the interview loop.

Candidates are sometimes given a case study or take-home assignment to prepare in the next round. Interviewees report being asked to either present a solution you led in your past experience or to present on a fictional company/problem - much like a consulting case study interview.

Tip: One interviewee actually had this call with the engineering manager of the team in which they'd serve as PM rather than a peer or the hiring manager, so be sure to clarify who your interviewer will be. This will help you prepare for follow-up questions.

Not all PM candidates are given a case study, so if you're entering the process with significant experience or through a referral, you may skip this step.

If you pass, you'll advance to the panel interview with anywhere from four to six 1:1 rounds. You may have as many as three rounds back-to-back, so expect to be "on your game" for an extended amount of time. Your panel interviewees can be quite diverse. One interviewee reported rounds with a peer PM and a technical director - another had multiple engineers. You'll face at least one director-level interviewee and at least one "culture fit" interview with someone outside the team you're interviewing for.

Expect the following question types:

  • Analytical
  • Behavioral
  • Product Strategy
  • Product Design
  • Execution

Let's look at each of these in more depth.

Sample Interview Questions


Behavioral questions will come up again and again throughout your interview as interviewers get to know you. The purpose of behavioral questions is to get the context of your resume and past experiences. The interviewer wants to understand why and how you made the decisions you did.

It is important to show that you will work well with everyone: product managers, engineers, designers, sales, and legal. Focus on communicating well: enunciate, speak slowly, and speak with meaning.

Prepare a clear, concise walkthrough of your resume. Have a “60 seconds to wow” pitch and be prepared to provide clear and in-depth explanations of each of your experiences that you’d want to highlight. These experiences can include previous work experience, side projects, classes, or even hobbies. Think about not only what you’ve achieved, but also what you learned, the challenges you faced, and the strategies you used to succeed.

Prepare real anecdotes so you can use specific examples. Your interviewer already has your resume so those anecdotes will add a more human touch to your application, making you more memorable. Think about anecdotes that show off how you were customer-obsessed, dealt with ambiguity, and had a growth mindset in approaching the task at hand.

Why do you want to work here? Why this role and team? Think carefully about why you are applying for this role, and why this team specifically. It helps to know as much about the role and team that you’re applying for. Try to watch tech talks or conference keynote speeches from the team online. It will also leave a good impression if the candidate has used the feature previously, and can speak to it. At that point, the interviewer will likely probe you for feedback on the product. Use this opportunity to show how you would converse and work with your interviewer as if you are already a member of the team.

To put your best foot forward, record yourself speaking. Many people have weird quirks about the way they present themselves. Some may jiggle or shake their leg. Others may use excessive filler words (like uh or um). It is nearly impossible to catch these quirks on your own. So, recording and re-watching yourself is a good way to be more cognizant of how you are presenting yourself.

Examples of behavioral questions:

  • Why PM?
  • Why do you want to join Twilio?
  • Tell me about a time you failed.
  • How do you influence team members without having direct control?
  • Why are you leaving your current job?
  • What’s the hardest problem you’ve ever had to solve?
  • Have you ever had to manage disagreement in your team?
  • Which of Twilio’s values appeals to you the most?


With analytical questions, you will be presented with a situation and asked to provide some analysis. Here, the interviewer wants to see how you reason with metrics and how you can think critically about user feedback and bugs.

Be prepared to answer questions like:

  • If a given metric is down, how will you investigate the problem?
  • Given a new product (say, Twilio SendGrid Email API what is the product goal and north star metric?
  • How do you use data to make product decisions?

Be prepared to face pushback on any assumptions you make. Don't immediately start answering - practice answering questions in a structured way. Successful candidates consider all variables and scenarios before diving into the nitty-gritty details.

Product Design

Product design questions test your ability to design a new product or improve an existing one.

Our #1 piece of advice? Be user-focused. The key is to ensure you're organized with your thoughts and have a clear goal in mind that will solve the user's problem(s).

You can explore some product questions from Exponent’s course below. Try them on your own and compare your answers to the solutions provided.

One of the best frameworks is to go "broad then deep". First, "go broad" by listing all the ideas and solutions that come to mind. Then, pick one to "go deep" on and explain why that is the solution you chose.

Another approach we see candidates have success with is The Triangle Method. This framework will help you articulate your thoughts and help nail your points into the interviewer's mind. To accomplish this, first list three points. Then, dive into each point. Finally, summarize your three points at the end. This will help you articulate your points and subpoints.
