Show HN: We built a multimodal AI interviewer for mock system design interviews (opens in new tab)

Hey HN! We’re Jared, Shreyas, and Varun the creators of TechInterviewer. We’re building a product for software engineers to go through an entirely simulated systems design interview. Our AI interviewer, Steve, gives you a prompt and you talk out loud and draw on a whiteboard while Steve guides you through the interview and gives real-time feedback. Check out our demo:

https://app.techinterviewer.ai

Every software engineer today has to prepare for systems design interviews and have two awful options: pay hundreds of dollars for a single session with a FAANG engineer or follow silently alongside a YouTube playlist. Because there is no instant feedback while practicing, engineers often learn about their most important knowledge gaps during the course of the interview loop.

Jared and Shreyas are both senior engineers who have spent 1000s of hours preparing for and administering systems design interviews. Shreyas was an early engineer at Deepgram and spent many years tracking developments in the TTS (text to speech) space. He realized that voice interviews had potential to change the candidate experience when he starting using chatGPT to prepare for interviewing founding engineer candidates at his startup.

We’re hoping that having easy access to interview feedback will level the playing field of software engineers at different skill levels. We’re really excited to share this with you all and we’d love any thoughts, feedback, and comments

Just checked this out! This is awesome.

I've built an SEO minded interview app, just audio, realmockinterviews.com

Perhaps we should do intros?

I just did a trial and submitted my email on the app.

I tried the product and I don't think this intro does it justice – this is a surprisingly authentic experience that I didn't think consumer AI was ready to do. There were definitely some rough edges, but this feels good enough to pay for as a tech screen.

Really appreciate the kind words and excited for others to have a similar experience!

This is really cool and sounds super authentic. Any chance you can share the TTS API/model you are using? Is it the OpenAI Whisper model?

Thanks so much! We're using 11 labs (https://elevenlabs.io/docs/api-reference/text-to-speech) under the hood, but can't speak too much into the exact configuration of the model we're using and the dynamics we're setting given a certain text. Hope that helps!

Let us know if you have any feedback on the experience!
