--- title: Greenroom — AI Mock Interviews from Your GitHub description: Greenroom is an AI mock interview platform that reads your GitHub and asks about what you've actually built. Voice conversations, instant feedback, free to start. url: https://usegreenroom.app/ last_updated: 2026-06-04 --- For engineers who know their craft but freeze when it counts # You're not scared of the *questions.* You're scared of freezing. Most interview prep teaches you facts. Greenroom teaches you to be yourself under pressure — by practicing with an AI that asks about your actual code, the projects you've shipped, the decisions you made. When they ask about your work, you should feel more confident than anyone in the room. Practice real interviews with an AI that reads your actual code, then tells you exactly what to fix.

Questions from your repos. Specific feedback after. Not a quiz — a conversation with a senior engineer. Greenroom · Interview with Ari · redis-job-queue A redis-job-queue Why did you choose **at-least-once delivery** over exactly-once in your job queue? Walk me through the trade-offs you considered. Listening... You So the main reason we chose at-least-once was simplicity of the consumer logic. With exactly-once you need distributed transactions or an idempotency layer, and at our scale the duplicates were rare Personalised ## Questions built from your actual work Ari reads your repos before the session starts. If you built a Redis-backed job queue, expect a question about your delivery strategy — not "explain Redis." Every session is unique to you and impossible to game with memorized answers. // Your repo: redis-job-queue + "Why did you choose at-least-once delivery over exactly-once? Walk me through the trade-offs." // Not the generic version: – "Explain the difference between Redis and Memcached." Voice-first ## A real conversation, not a form Real interviews are conversations. Ari listens, responds, and pushes back — like a senior engineer across the table. Typing answers into a box doesn't build the muscle that matters on the day. Ari is listening **Ari:** "Walk me through how you handle backpressure in your queue." **You:** "So when the queue fills up, we..." Honest feedback ## Specific. Not a score. Three sentences: what you showed, what was thin, how you came across. Nothing vague. No "great job." No arbitrary percentiles. Just what to fix before the real interview. ✓ Strong Clear ownership of the caching layer. You explained the TTL trade-off without prompting. ~ Thin Didn't address failure modes. A senior interviewer will follow up here — you need a sharper answer. ! Watch out "I think," "maybe," "kind of" — over-qualifying every answer reads as uncertainty even when you're right.

Real interviews. ★★★★★ "Finally an AI that actually reads my projects. It dug into my CAD optimization project and grilled me on tolerance stack-up and material trade-offs — exactly what a real interviewer would catch. Felt way more prepared after just two sessions." N Nikhil Mechanical Engineer · Really helped with interview prep ★★★★★ "I come from a BBA background so I was nervous about case and HR rounds. Greenroom helped me structure my answers and speak confidently — made a real difference in how I showed up." S Shivam BBA Graduate · Made a big difference ★★★★★ "The website looks really clean and well organized. It feels easy to use, and nothing seems unnecessarily crowded or confusing. The overall experience is smooth, and it gives a reliable and professional impression." R Rakesh Full Stack Developer · Changed how I prepare ★★★★★ "Used it the night before my screening and it gave me a question almost identical to what I got asked. The GitHub analysis is genuinely impressive — questions about code I actually wrote." N Nithish Kumar Software Engineer · Exactly what I needed ★★★★★ "Three failed interviews in a row, then I found Greenroom. The feedback after each session showed me exactly where I was losing marks. Passed my next two rounds back to back." S Shankar ML Engineer · Would highly recommend ★★★★★ "I built Greenroom to solve my own problem — I kept blanking in interviews despite knowing the material. Practicing out loud with an AI that actually read my projects changed everything for me." M Mohammed Faheem Founder · Built this for all of us ### Share your feedback Tried Greenroom?
