4. Sends the data and job description to ChatGPT
5. Asks ChatGPT to analyze the resume based on the job description
6. Displays the results in the app

Here's what you'll need:

• Basic understanding of Python

Steps to build the app:

1. Define the app's functionality:

   • Get the job description (text format)
   • Get the resume (PDF format)
   • Extract data from the resume
   • Send data and job description to ChatGPT for analysis
   • Display the analysis results in the app

2. Set up the backend:

   • Install libraries: pip install streamlit pypdf2 openai
   • Use Streamlit to create the app's interface: header, form to upload resume and enter job description
   • Write code to handle form submission and store data in variables

3. Extract text from the PDF resume:

4. Extract resume data using ChatGPT:

   • Send the prompt and resume text to ChatGPT
   • Extract the relevant information (name, experience, ratings) from ChatGPT's response

5. Display the reviewed resume in the app:

   • Use Streamlit elements to display the extracted information (name, experience, ratings) from the resume
