Preparing for a Product Manager interview at Synthesia requires a balanced approach that covers both product strategy and technical execution. You cannot rely on generic PM frameworks; instead, you must demonstrate a deep understanding of generative AI, system architecture, and rigorous quantitative reasoning.

To stand out, focus your preparation on the following key evaluation criteria:

Product Sense – You must demonstrate a highly structured, user-centric approach to problem-solving. Be prepared to identify user pain points, define target personas, and design creative, technically feasible solutions.

Quantitative Reasoning – You will be tested on your ability to work with numbers. This includes market sizing, business case development, metrics definition, and analyzing unit economics.

Technical Literacy – You need to show that you can partner effectively with engineering. You should understand high-level system design, APIs, cloud infrastructure, and the basic principles of machine learning models.

Leadership & Culture Fit – You must prove that you can lead through influence, navigate ambiguity, and thrive in a fast-paced, collaborative environment.

The interview process at Synthesia is rigorous, comprehensive, and highly structured, often consisting of around 7 stages in total. The loop is designed to look closely at your product capabilities through Meta-style case studies, deep technical evaluations, and collaborative problem-solving. Candidates frequently describe the process as challenging but highly enjoyable, with a strong emphasis on transparency and mutual respect.

The journey begins with a standard recruiter screen to align on your background and motivation. This is quickly followed by a call with the hiring manager or Head of Product, which often includes a mini case study and a quantitative market-sizing exercise. From there, you will move into a take-home case study, followed by a live presentation and multiple rounds of deep-dive product sense and quantitative reasoning interviews with peer PMs. The final stages involve high-level technical and architectural discussions with the SVP of Engineering and the CTO.

The visual timeline above outlines the typical progression from your initial application to the final offer. Candidates should expect a fast-paced and well-executed process, but should plan to dedicate significant time to preparing for the intensive case study rounds. Because the late-stage interviews involve the executive engineering team, ensuring your technical foundation is solid is critical to succeeding in the final stretch.

To pass the rigorous Synthesia PM loop, you must excel across four primary evaluation pillars. Each of these areas is tested through dedicated interview rounds.

Product Case Studies

Product case studies at Synthesia are highly structured and closely mirror Meta-style product sense interviews. Interviewers want to see how you approach vague, open-ended prompts and turn them into concrete product roadmaps. You will be evaluated on your ability to empathize with users, prioritize systematically, and design elegant solutions.

Be ready to go over:

• User Segmentation – How to break down a broad user base into actionable target personas.
• Pain Point Identification – Pinpointing the most critical problems that, if solved, will drive the most value.
• Prioritization Frameworks – Using structured methods (like ROI, impact vs. effort) to decide what to build.
• Advanced concepts (less common) – Designing product loops for synthetic media virality, and managing user trust and safety in generative AI.

Example scenarios:

• "Design a browser-based collaborative editing tool for enterprise teams."
• "How would you integrate third-party translation workflows into the core video creation pipeline?"

Quantitative Reasoning

As a Product Manager at Synthesia, you must be highly analytical. You will face questions that require quick mental math, market estimation, and metric definition. The team wants to ensure you can back up your product intuition with hard data and economic reality.

Be ready to go over:

• Fermi Estimation – Sizing markets or usage volumes with limited initial data.
• Metric Frameworks – Setting up North Star metrics, input/output metrics, and guardrail metrics.
• Unit Economics – Understanding the relationship between compute costs, subscription pricing, and margin.
• Advanced concepts (less common) – Estimating GPU capacity requirements for a growing user base.

Example scenarios:

• "Estimate the annual revenue potential of a self-serve custom avatar feature."
• "We want to launch a new feature that increases rendering time by 20%. How do you evaluate if the user value justifies the cost?"

Technical Competency & System Design

You do not need to write code, but you must be highly technical. Your interviews with the SVP of Engineering and the CTO will explore your understanding of system architecture, APIs, and how software scales. You need to prove you can earn the respect of world-class engineers.

Be ready to go over:

• High-Level System Design – How data flows through a modern web application and video rendering pipeline.
• API and Integration Design – How partners and developers interact with Synthesia programmatically.
• Latency and Performance Trade-offs – Balancing processing speed with output quality.
• Advanced concepts (less common) – Understanding the high-level differences between training AI models and running inference at scale.

Example scenarios:

• "Walk me through the system architecture needed to support real-time preview generation for video editing."
• "How would you design a rate-limiting strategy for our public API to prevent system abuse while maintaining a great developer experience?"

Leadership & Collaboration

Because Synthesia is growing rapidly, PMs must be exceptional leaders who can align diverse teams. You will be asked behavioral questions that probe your communication style, your ability to handle conflict, and how you manage cross-functional stakeholders.

Be ready to go over:

• Stakeholder Management – How you align engineering, design, and business teams behind a single vision.
• Conflict Resolution – Overcoming disagreements on product direction or technical execution.
• Navigating Ambiguity – Making progress on initiatives when requirements or market conditions are shifting.
• Advanced concepts (less common) – Managing expectations when translating unpredictable AI research into predictable product roadmaps.

Example scenarios:

• "Tell me about a time you had to convince an engineering team to pivot away from a technical architecture they were excited about."
• "Describe a situation where a critical product launch was slipping. How did you handle the communication and execution?"

On a day-to-day basis, a Product Manager at Synthesia operates as the entrepreneurial leader of their product area. You will be responsible for defining the product vision, strategy, and roadmap for key parts of the platform, whether that is the core video editor, avatar generation pipelines, enterprise collaboration tools, or developer APIs.

You will spend a significant portion of your time collaborating cross-functionally. You will work with product designers to map out intuitive creation workflows, write detailed product requirement documents (PRDs) for engineering teams, and coordinate with AI research scientists to understand when new generative capabilities can be productized. Additionally, you will partner with product marketing and customer success to gather user feedback and ensure successful go-to-market execution.

Ultimately, your job is to deliver highly reliable, scalable, and delightful products. This means monitoring product health metrics, analyzing user behavior data, and constantly iterating on the product experience to drive engagement, retention, and business growth.

To be competitive for a Product Manager role at Synthesia, you must bring a mix of strong technical aptitude, exceptional product craft, and a highly analytical mindset.

• Must-have skills & experience:

  • Proven track record of managing complex software products, preferably in SaaS, developer platforms, or highly technical product areas.
