InterviewGPT

AI leetcode interviewer that assesses tech applicants. Built on Langchain and OpenAI APIs. Recruiter-focused and tracks progress and submits analysis to email.

Final features:

Interview content

• AI interviewer: provides focused and structured interviews, asking one question at a time and ensuring comprehension by asking follow-up questions before moving to the next question
• Two question types: code-based and concept questions
• AI interacts beyond simply asking the question; it follows up and asks you to elaborate depending on your answer.
• CLI with context: user-friendly experience with relevant information and instructions
  • "Please enter a valid file path"
  • "You can type in the chat for this question"
• Records transcript with code: - enables detailed review of candidate's coding abilities and problem-solving techniques - gives insight into what the candidate codes like
• Variable interview length: adjusts based on context, usually around 45 minutes.
• I only have access to GPT 3.5 API so outputs will be greatly improved when I get the new API

Backend

• Key validation on Firestore: enhances security, only registered candidates can access
• Generate new keys
• reference candidate emails

Candidate Results

• MIM-formatted email that prettifies the outputs so recruiters can read them easier
• Email notification: prompt feedback, improves candidate communication
• For the email text, I used langchain to summarize the transcript and provide scores, stats, and give verdict on candidate
• timestamps to measure speed; you can see how long the candidate took for each question, possible flagging if they answer too fast
