ElevenLabs Software Engineer Interview Guide

ElevenLabs runs one of the more distinctive software engineer loops among AI companies, built around whether you can ship a product end to end. Its product decomposition round asks you to design a customer-facing tool from the UI down to the data model, with little of the traditional system design you'd find in other SWE loops. At every stage, interviewers value product judgment alongside raw coding ability.

This guide breaks down each stage of the ElevenLabs software engineer interview, what interviewers look for, and how to prepare with example questions, actionable tips, and resources.

ElevenLabs software engineer interview process

The ElevenLabs software engineer interview process runs on product ownership and moves faster than most big tech loops, often completing within a few weeks. When you reach the onsite, the recruiter sends a PDF outlining what each interview covers, so you can prepare for the exact format.

Here's what the interview process can look like:

1. Recruiter screen: A conversational call about your background and the work you've owned
2. Coding screen: A timed CoderPad assessment of your fundamental coding skills
3. Virtual onsite: Three interviews covering behavioral depth, practical coding, and product decomposition

Recruiter screen

The ElevenLabs SWE recruiter screen runs deeper than a standard scheduling call, and it sets the tone for how the team evaluates your experience. You'll walk through your background and the projects you've driven end to end, and the recruiter will explain how the role fits the team.

Because ElevenLabs treats engineers as owners, this call focuses on what you've shipped and why it mattered. It's also your chance to show genuine interest in the company's work.

Interviewers look for:

• End-to-end ownership: Whether you've driven projects from idea to production yourself
• Product motivation: Why you built what you built, and the tradeoffs you made
• Mission alignment: Whether you care about audio, voice AI, and the challenges ElevenLabs works on
• Role fit: How your focus maps to the team's backend, front-end, or growth needs

Sample questions

Here are example questions to prepare for:

• Why do you want to work at ElevenLabs, and what draws you to audio or voice AI?
• What tradeoffs did you make on a recent project, and why?

Coding screen

ElevenLabs opens its software engineering evaluation with a coding screen, a timed CoderPad assessment you complete on your own. You'll have roughly 90 minutes for two to three medium-difficulty questions, and they don't need to relate to ElevenLabs's own products. Most candidates use Python, but you can work in the language you're strongest in.

Working alone, you can test and refine your solutions before you submit. For front-end-leaning roles, this stage varies: some candidates get a live React exercise, and others a multi-day take-home that mixes React with algorithm questions, so confirm your track with the recruiter.

Interviewers look for:

• Data structures and algorithms: How cleanly you solve medium-difficulty questions under time constraints
• Code quality: Whether your solutions are correct, readable, and tested
• Independence: How efficiently you work without an interviewer guiding you
• Front-end fluency: For front-end tracks, your comfort building and debugging in React

Sample questions

Here are example question types to prepare for:

• A graph or tree traversal question.
• For front-end tracks, a bug to find and fix in a small React app, such as an audio transcription tool where the text falls out of sync with playback.

Behavioral round

The ElevenLabs SWE behavioral round is a deep dive into the projects you've personally owned, with the focus on work you led or built alone. Your individual contributions matter most, so team-level accomplishments count for less than what you drove yourself.

Expect values and motivation questions to surface across other rounds as well, since ElevenLabs folds culture signals throughout the loop. You can use this time to show why autonomy suits you and where your product instincts come from.

Interviewers look for:

• Individual ownership: Whether you drove projects yourself or leaned on a team
• Product motivation: Why you chose to build what you built
• Shipping to production: Whether your work reached real users and held up
• Mission fit: Whether you have a genuine interest in audio, voice, or AI
• Communication: How clearly you explain your decisions and tradeoffs

Sample questions

Here are example questions to prepare for:

• Tell me about a product you built and shipped end to end.
• What was the hardest technical tradeoff you made, and how did you decide?
• Why did a project you started ship, or why didn't it?

Practical coding round

In the ElevenLabs SWE practical coding round, you'll solve a hands-on challenge modeled on a real customer workflow. You might work through an audio file management, dubbing, or review workflow, applying data structures and algorithms to build something usable.

The interviewer may give you function stubs and sample data that point toward a specific solution they already use internally. Stay flexible, since they may want you to adjust your approach to match it.

This tends to be the most demanding round, so budget your prep accordingly.

Interviewers look for:

• Hands-on execution: How you turn a messy, real-world task into working code
• Data structure choices: Whether your design fits the workflow's constraints
• Adaptability: How you respond when the interviewer nudges you toward another approach
• Product awareness: Whether your solution serves the customer's real need

Sample questions

Here are example questions that reflect the workflows candidates describe:

• Build a tool that processes and organizes a batch of audio or video files.
• Given a manual review workflow, implement the backend logic that automates it.
• Take a spreadsheet-driven process and turn it into structured, maintainable code.

Product decomposition round

The product decomposition round is ElevenLabs's answer to the system design interview, and it's the stage that surprises the most candidates. You won't write code; you'll design a tool that solves a common customer challenge, working from the user interface down to the backend and data model.

The name comes from the expectation that you can break a whole product into its parts and reason about each one. This round runs closer to product management than classic architecture, so treat it as a product design conversation.

Traditional system design questions rarely appear, so prepare to talk through users, use cases, and tradeoffs out loud. This emphasis reflects how ElevenLabs works: it has historically operated without dedicated product managers, so engineers own product decisions end to end.

Interviewers look for:

• Product decomposition: How well you break a product into UI, services, and data layers
• User focus: Whether you start from the customer's real need
• Tradeoff reasoning: How you balance scope, complexity, and roadmap priorities
• End-to-end thinking: Whether you can reason about every component you propose
• Communication: How clearly you explain a design without a whiteboard

Sample questions

Here are example prompts to prepare for:

• Design a tool that lets customers review and correct AI-dubbed video.
• Design a system for managing and versioning generated audio files.
• Walk through the UI and data model for a self-service voice-cloning feature.
• Design an internal tool that lets support agents find and re-run failed overnight dubbing jobs, and be ready to reason about retries, rate limits, and errors that can't be retried.

How to prepare for the ElevenLabs software engineer interview

1. Present yourself as a builder: Pick two or three projects you drove from idea to production, and be ready to explain the outcome of each one, good or bad. Lead with what you owned yourself, since ElevenLabs looks past team-level accomplishments for evidence of individual ownership. Pick moments where you spotted a gap and closed it without being told.
2. Show genuine interest in audio and AI: Come with a specific reason you care about voice, audio synthesis, or generative AI, since interviewers want people who believe in the work. Pointing to a side project or a product you admire is more convincing than general enthusiasm.
3. Prepare for product-led design, even on the backend: Practice taking a manual or messy workflow, such as audio dubbing or review, and turning it into both backend logic and a usable UI. Backend-leaning candidates still face product-heavy questions, so practice explaining your design choices from the user's point of view.
4. Practice medium-difficulty coding under time: Work through two to three medium questions in a 90-minute window to match the CoderPad screen's format. If you're on a front-end track, add React debugging and basic algorithms, since the take-home mixes both.
5. Clarify the format before each stage: Ask the recruiter what each round covers, and use the PDF they send to confirm what kind of decomposition to expect.
6. Be ready to discuss how you use AI: ElevenLabs builds and uses AI agents across its own hiring, and interviewers may ask how AI fits into your engineering workflow. Have an honest account of where AI speeds you up and where you still own the decisions.
7. Run a mock interview: Practice a full loop with peer or AI mock interviews to get feedback before your interview. For targeted help, work with an expert coach.

About the ElevenLabs software engineer role

ElevenLabs software engineers build the products and tools that turn the company's audio and voice research into something customers can use. The work spans the full stack, and it shifts with the needs of the team you join.

ElevenLabs SWEs typically work on:

• Building product features on top of the research team's audio and voice models
• Creating custom, scalable services for specific customer needs and industries
• Full-stack work across UI, front-end, backend, and infrastructure
• Partnering with growth teams to drive product adoption and self-service

ElevenLabs software engineer experience requirements

ElevenLabs doesn't publish fixed requirements for its SWE roles, and expectations shift with the team's focus. A backend-leaning role may call for cloud infrastructure and Kubernetes experience, while a front-end track leans on React.

The bar to reach the onsite is high, so strong general engineering skills matter more than any single credential. ElevenLabs values a track record of building and shipping real projects, including work you did in school.
