LastRound AI is a candidate-side interview copilot for people in active job-seeking mode. Unlike recruiter-facing screeners, the tool sits with you during your live interview and surfaces real-time prompts when a question lands.

The product covers three round types that decide tech offers in 2026: technical coding rounds (data structures, system design, debugging), behavioural rounds (STAR-format storytelling, manager-fit conversations), and product or domain rounds (case interviews, deep-dive questions). It works on Zoom, Google Meet, Microsoft Teams, and asynchronous platforms including HireVue and Ribbon AI.

Beyond the live copilot, the platform includes a complete job-search toolkit:

- Mock Interviews with full STAR evaluation and structured feedback

- Resume Builder tuned for ATS systems and tech recruiter expectations

- Job Search across active openings with smart matching to your profile

- Company Insights covering hiring processes, interview loops, and salary bands at FAANG, Stripe, Anthropic, OpenAI, and 200+ other companies

- Concept Explainers for system design topics, algorithms, and behavioural frameworks

- A 7,000+ question bank with company tagging and difficulty progression

- A mobile copilot for in-person interviews and phone screens

Under the hood, the live copilot streams audio from your meeting, runs low-latency speech-to-text, classifies the question type, and produces a structured answer scaffold using a frontier language model fine-tuned on real interview transcripts. The result lands in a side panel within 2 to 3 seconds. You stay in control of phrasing, voice, and delivery.

The candidate-side focus, real-time latency, and the breadth of the end-to-end job-search toolkit are what distinguish LastRound AI from screening tools, mock-only platforms, and post-hoc analytics products.
