Most tools help you solve problems. FirstOffer helps you perform. We simulate real technical and behavioral interviews where you think out loud, explain tradeoffs, and handle follow ups under pressure. Paste a LinkedIn job and the interview adapts to that role. Code in a shared IDE and collaborate on a live whiteboard. Get real time feedback on communication, structure, and technical depth. Practice FAANG style questions and train like it is the real thing.

I built FirstOffer because even after solving 176 LeetCode problems, I still felt uncomfortable in live interviews. Solving problems alone is different from explaining your thinking under pressure while someone evaluates you. When I tried existing mock interview tools, the experience felt unnatural. Agents would interrupt you mid response, latency broke the flow, and the conversation felt like a stitched together speech to text to LLM to text to speech pipeline. It did not feel like a real interview. Most platforms only offered an IDE at best. Real interviews involve collaboration, communication, and whiteboarding. So I built FirstOffer to replicate the real experience. A shared IDE, a live whiteboard, uninterrupted conversation flow, and interviews modeled after real FAANG formats. Mock interviews should not be easy. They should prepare you for the real thing.
