What this interview will probe
Build the agentic experiences inside Perplexity's Comet browser, creating AI agents that autonomously navigate and act on the web using context engineering, tool interfaces, and browser automation (CDP, Playwright, extensions). You'll work across AI/ML, backend, and full-stack with a high bar on both agent performance and user experience. A technical interview would probe context-window and tool-calling design for frontier models, browser-automation reliability, and how you'd evaluate and harden a web-navigating agent against flaky, adversarial pages.
