    - Output Parsing: The results from the AI evaluation are structured into a predefined format for easier handling.
    - Google Sheets Integration: Finally, the parsed information along with the resume text is appended to a specified Google Sheets document for record-keeping and further analysis.

    - Change Evaluation Criteria: Update the AI agent's system message to tailor the evaluation criteria according to specific job requirements or company standards.
    - Adjust Google Sheets Columns: Customize the columns in the Google Sheets integration to include additional fields relevant to your hiring process, such as position applied for or interview status.
    - Enhance Output Parser: If needed, modify the output parser schema to capture more detailed information from resumes or change the format of the extracted data.
