Are these based on real engineering roles?
Yes. The catalog is built around real engineering role patterns so the practice round feels closer to a live interview.

Replit
Security
Lead Security Engineer
Lead security for Replit's AI coding products, pioneering research on the security of AI-generated ("vibe coded") software and working directly with the Agent to make its code generation safer for millions of developers. The role blends traditional application and cloud security with novel LLM-specific threat modeling like prompt injection and insecure code synthesis. A technical interview would probe web and cloud vulnerability classes, securing multi-tenant code-execution sandboxes, and how to detect and mitigate security flaws introduced by an LLM at generation time.

ML / AI
Senior Software Engineer, Agent Platform
Build the platform and tooling that lets product engineers rapidly iterate on Replit Agent, the AI system that turns natural-language prompts into working software, while improving the core agent loop itself. The work spans prompt and tool orchestration, evaluation harnesses, and the feedback loops that make an autonomous coding agent more reliable. An interview would probe LLM agent architecture, designing evals and guardrails for non-deterministic systems, and reasoning about tool-use, context management, and failure recovery in long-running agent runs.

Infrastructure
Software Engineer, Compute Platform
Build and scale the distributed compute infrastructure that runs millions of user workspaces and powers apps created by Replit Agent, optimizing performance and efficiency across global regions. The role covers container orchestration, resource isolation, and launching new cloud primitives that the Agent uses to deploy complex applications. A technical interview would explore distributed-systems fundamentals, container/VM isolation and scheduling, and how to drive down cold-start latency and cost while keeping multi-tenant workloads secure.
GoRustKubernetesReplit
Fullstack
Staff Software Engineer, Product
Drive end-to-end development of Replit's core product surfaces, building the collaborative web IDE and the user-facing flows that connect people to the Agent and to live deployments. The role spans React frontends, Node/TypeScript services, and the real-time collaboration layer, with broad technical ownership across the stack. An interview would explore full-stack system design, real-time collaboration and conflict-resolution (CRDT/OT-style) problems, and how to ship cohesive features fast across frontend and backend at high quality.

FAQ
Is the interview voice-based?
Yes. ExoForm runs a live voice interview, asks follow-ups, and produces structured feedback after the session.
Can I try it for free?
Yes. You can start with the free interview allowance before upgrading for more practice.
