The AI-Agent-Driven Job Search & Application Automation Project leverages agent-based AI to streamline the job search and application process. This project automates the retrieval of job listings, customizes cover letters, and submits applications via email.The system integrates the Adzuna API for job listings, natural language processing (NLP) to extract key skills and match job descriptions, and email automation for streamlined application submission. Real-time job application tracking is facilitated through Google Sheets and an interactive Streamlit dashboard. By reducing manual effort and optimizing the job application process, this project offers a more efficient, personalized experience for job seekers. Future work aims to enhance the system's capabilities by integrating additional data sources, improving NLP processing, and refining user experience.

1. Introduction

The AI-Agent-Driven Job Search & Application Automation Project aims to harness the capabilities of agent-based AI to transform the job search and application process. In today’s competitive job market, candidates often struggle with managing and optimizing their search efforts, tailoring resumes, and submitting applications efficiently. This project addresses these challenges by deploying autonomous AI agents that streamline the entire job-hunting experience from identifying relevant job opportunities to submitting customized applications. By integrating intelligent agents, large language models (LLMs), email automation, and follow-ups through Google Sheets the project seeks to drastically reduce the time and effort involved in job applications, delivering a more efficient and personalized experience for users.

2. Methodology

The AI Job Application Automation project leverages a series of advanced models and packages to automate the process of job application submission and tracking. Below is the methodology, outlining the key models and packages used at each step:

2.1 Data Collection and Scraping Methodology:

Job listings are collected from the Adzuna API using predefined job titles and a specific location. The Adzuna API was selected due to its open access with an API key and a generous free tier of 5,000 requests per month. In comparison, other platforms like LinkedIn, Indeed, and Glassdoor either require approval or offer limited, paid access. This makes Adzuna the most practical option for a scalable, cost-effective solution for job scraping.

All job listings used in this project are freely available on Adzuna.- https://www.adzuna.com/

The process involves:

• API Integration: Accessing Adzuna's job listings via API using application IDs and keys.

• Targeted Search: Querying the API for job data based on job titles and locations. For instance, searching for titles such as "Data Scientist", "Software Engineer", or "Machine Learning Engineer" ensures that the job data returned is tailored to specific roles.For example, a location might be specified as "London" to ensure that only jobs within that geographical area are included in the search results.

• Data Extraction: Collecting key job details such as job title, company, location, salary, description, and application link.Let explain each:Job_title: The specific role or position being advertised. Helps job seekers identify the exact role they’re interested in applying for.Title: The public title of the job. Provides clarity on the role being offered.Company: The name of the company hiring. Allows job seekers to identify potential employers.Location: The job’s geographical location. Helps applicants decide if the location fits their preferences.Created: The date the job was posted. Helps job seekers find newly listed jobs.
  Description: An overview of job responsibilities and qualifications. Allows applicants to assess if they’re a good fit.Salary_min: The minimum salary offered. Helps job seekers assess if the compensation meets their expectations.Salary_max: The maximum salary offered. Assists in evaluating if the job aligns with financial goals.Contract_type: The type of employment (e.g., permanent, temporary). Helps applicants filter based on job stability preferences.Contract_time: The time commitment required (e.g., full-time, part-time). Allows job seekers to choose based on availability.Data Storage: Storing collected data in a local SQLite database for easy retrieval

The example of dataset shown in the table below.

2.2 Natural Language Processing (NLP) for Data Processing

Once the job listings are scraped, job descriptions are processed using NLP to extract key details and personalize content. This ensures that applicants can efficiently tailor their applications to the specific job requirements.
The experiment uses en_core_web_sm model . The en_core_web_sm model is a lightweight, pre-trained language model from spaCy, used for various NLP tasks, including Named Entity Recognition (NER), tokenization, part-of-speech tagging, and dependency parsing. In the context of job listing processing, it identifies key entities such as job titles, company names, and locations. The model's ability to perform tokenization and lemmatization aids in extracting relevant keywords from job descriptions. It processes text quickly and is suitable for applications requiring fast processing with moderate accuracy. This model is leveraged to extract structured information, enabling efficient job matching and application automation.

2.3 Cover Letter Generation

The cover letter generation process begins by extracting key skills from the job description using predefined skill lists and NLP techniques, such as tokenization. It then extracts relevant work experience and contact information from the user's CV, which is parsed from both PDF and DOCX formats.The system identifies sections related to experience using keywords such as 'experience,' 'work,' and 'role.' It also extracts the user's name and contact information from the document’s header while handling variations in formatting. The extracted data is then used to populate a dynamic cover letter template, ensuring a personalized and professional letter tailored to the job title, company, skills, and experience. The final output is a personalized cover letter ready for the user’s application.

2.4 Email Automation Process

The email automation process begins by composing an email using the smtplib and email packages, with the cover letter and CV attached. The email is sent via an SMTP server, such as Gmail, using login credentials securely retrieved from environment variables. The subject and body are dynamically populated, and the email is sent using the SMTP sendmail() function after establishing a secure connection. Users have the option to review and modify the email content before submission.. The process includes logging to track the success or failure of each email, with pandas used for managing the statuses of sent emails, ensuring successful delivery tracking. Error handling is implemented to log and report any failures encountered during the email sending process.

2.5 Job Application Tracking and Dashboard (Google Sheets and Streamlit)

Google Sheets serves as the backend database, while Streamlit provides an intuitive, user-friendly interface for managing job applications efficiently, allowing users to filter applications by status, date, or job title. Job application details, such as status and job title, are logged and updated directly in the sheet as users interact with the system.

Streamlit is used to create an interactive dashboard where users can view job listings, upload CVs, generate personalized cover letters, and update their application statuses. The dashboard displays job details and application status, allowing users to track progress easily. Upon submitting or updating an application, changes are reflected in real time in the Google Sheets document.

In summary, Google Sheets functions as the backend database, while Streamlit provides an intuitive, user-friendly interface for managing job applications efficiently.
