TalkThrough

Inspiration

The interview process is a universal hurdle that everyone inevitably needs to go through to advance their career. We also realized that many existing interview prep tools are static and silent, leaving out key aspects of real interviews like communicating under pressure. Thus, TalkThrough was created to be an attentive coach that bridges the gap between solving a problem and effectively explaining it to an interviewer.

What it does

TalkThrough is an AI interview suite that immerses users into mock interview sessions and gives a personalized analysis of previous performances. We have a Technical Track where users solve algorithmic "Leetcode" style problems in a real-time editor while explaining their logic and thought process out loud. The AI will then evaluate the code's correctness alongside verbal clarity and complexity analysis. The Behavioral Track for users to practice answering common behavioral questions looking for responses in the STAR format. It also gives users an option to upload your resume and receive questions related to previous experiences.

How we built it

Voice Stack: Deepgram Nova-3 + Aura for STT and TTS
Frontend: React + Vite
Styling: Tailwind CSS with custom theme
Storage & Data Persistence: LocalStorage for history log
Reasoning: OpenAI (GPT 3.5) via OpenRouter

Challenges we ran into

Loading the resume PDF file was too slow so we decided to make it a text box
Scores were often heavily biased and fixed this through better reasoning

Accomplishments that we're proud of

Technical Interview solution analysis that includes time complexity and code correctness
Quick transcription (STT <-> TTS) implementation using Deepgram
Intuitive and immersive UI making it easy for users to navigate
