ElevenLabs's Interview Process (2026)

Blog / ElevenLabs's Interview Process (2026)
ElevenLabs Interview Process
The ElevenLabs software engineer interview process is fast-moving and product-focused, typically wrapping up in two to four weeks from application to offer. Most candidates report four to five stages, with a strong emphasis on ownership, practical coding, and thinking beyond the code itself.
  • AI Agent / Recruiter Screen: The process often kicks off with an interaction with one of ElevenLabs' own conversational AI agents (Becky or Oscar), followed by a 30-minute video call with a human recruiter covering your background, interest in AI audio, and ability to work autonomously in a remote-first environment.
  • Online Assessment: An asynchronous coding challenge, usually around 60 to 90 minutes, hosted on CoderPad with two LeetCode-medium style problems. Interviewers are looking for clean, idiomatic code, not just passing test cases.
  • Technical Screen: A 60-minute live coding session with a peer engineer covering algorithmic problem-solving, often involving topics like tree traversals, cycle detection, or string manipulation.
  • Virtual Onsite (The Loop): Usually three to four back-to-back sessions covering a practical coding round, a Product Decomposition / system design round, and a behavioral round. This is the most distinctive part of the ElevenLabs process.
  • Hiring Manager / Founder Sync: A final 30-minute conversation focused on vision, culture fit, and your motivations for joining, often with a senior leader or founder.
To prepare effectively, focus your study plan across these key areas that ElevenLabs consistently tests:
  • Data Structures & Algorithms (DSA): Algorithmic problem-solving tested in both the online assessment and technical screen.
  • System Design: Async processing, low-latency APIs, and end-to-end architecture for audio workloads.
  • Product Decomposition: A unique hybrid round where you design the UI, API, and backend for a real-world manual workflow.
  • Frontend / React: State management, component debugging, and how the frontend consumes backend APIs.
  • Behavioral: Ownership-heavy questions focused on what you have built, shipped, and learned from.
1. Data Structures & Algorithms (DSA)The online assessment and technical screen both lean on LeetCode-medium problems, with some candidates reporting harder questions in the live round. Topics like linked list cycle detection, binary tree inorder traversal, sliding windows, and string manipulation come up frequently.For the live technical screen, expect to talk through your reasoning as you code. Interviewers care about your thought process and code quality, not just whether you reach the correct answer.A solid starting point is working through our top 100 DSA questions, then drilling into specific weak spots. Pay particular attention to trees and linked lists, which candidates consistently flag as high-frequency topics at ElevenLabs.
2. System DesignElevenLabs system design questions are grounded in the product itself, so expect scenarios around async processing, handling large audio files, and building low-latency APIs rather than generic textbook problems. A classic example is designing a worker system that processes asynchronous dubbing requests from a spreadsheet-style input.Brush up on High-Level Design concepts with a focus on queue-based architectures, rate limiting, and fault tolerance for media workloads. Practicing with our System Design AI Whiteboard can help you get comfortable diagramming these end-to-end systems under time pressure.Understanding system design core concepts like caching fundamentals and networking fundamentals will also strengthen your answers when the interviewer probes deeper on latency or reliability tradeoffs.
3. Product DecompositionThis is the round that sets ElevenLabs apart from most other SWE interviews. You are given a messy, manual workflow (think a Disney dubbing spreadsheet) and asked to design the UI, the API, and the backend infrastructure end-to-end. It is equal parts engineering and product thinking.The goal is to show that you can reason about the user experience and minimize friction, not just scale a database. Practice taking an ugly real-world process, like a CSV export or a manual approval workflow, and walking through how you would automate it from front to back.This round rewards candidates who have built and shipped their own products. If you have side projects or portfolio work, prepare concrete stories about the decisions you made and why.
4. Frontend / ReactFrontend and fullstack candidates should expect a practical coding round where you debug or extend a real-world React component rather than solving a clean algorithmic problem. One commonly reported scenario involves fixing a React-based audio transcription tool where text highlighting falls out of sync with audio playback.Strong React fundamentals are important, particularly around state management, useEffect behavior, and how components consume API responses. Interviewers are testing whether you can read messy code quickly and reason about side effects under pressure.Even for backend-focused roles, ElevenLabs expects you to understand how the frontend consumes your APIs during the Product Decomposition round, so a working knowledge of React is worth investing in regardless of your specialization.
5. BehavioralElevenLabs behavioral questions are heavily ownership-driven. Expect prompts like 'Tell me about a side project you took to production' or 'Why did your last project fail to ship?' rather than generic situational questions.The company explicitly looks for engineers with a founder mindset, so frame your answers around the business impact and user experience of your work, not just the technical implementation. Using the STAR principle to structure your answers keeps your stories focused and easy to follow.Review the Behavioral Playbook and prepare three to four strong stories about projects where you owned the outcome from start to finish. Stories about side projects or early-stage startup work tend to resonate especially well here.
ConclusionElevenLabs moves fast, so start preparing early and prioritize the Product Decomposition round since it is the most differentiated part of the process and where many candidates are caught off guard. Use the product yourself before your interviews, and come ready to talk about your own shipped work. For a structured, step-by-step plan covering every stage, follow the ElevenLabs Interview Roadmap and build toward your offer systematically.
