This is a fascinating project, thank you for sharing! I agree with the previous comment that providing more context for new visitors about what to expect would be beneficial. I also share the same concerns about data retention, as it's crucial for user privacy.<p>Additionally, I noticed that you've used Vapi.ai and elevenlabs.io, both of which seem like powerful tools. I'm curious, how did you decide on using these two? Did they meet all your needs, or did you encounter any challenges during their use?<p>Lastly, I think the idea of a mock interview is excellent, as it can help applicants better prepare for YC interviews. I look forward to seeing further developments on this project!
