Resume Optimisation and Suggestions using Large Language Models: A Review

Abstract

In the rapidly evolving job market, the compatibility of a candidate\'s resume with the job description is critical to the application process. Conventional resume optimization techniques frequently depend on keyword matching, which is shallow and cannot comprehend linguistic nuances or context, resulting in an inadequate match between applicant\'s profiles and job criteria. This study presents a novel application that uses Bidirectional Encoder Representations from Transformers (BERT) to generate language embeddings from job descriptions and resumes, therefore bridging this gap. Our program offers a context-aware and nuanced evaluation of how well a candidate\'s qualifications match the requirements of the position by calculating the similarity scores between these embeddings. Furthermore, the incorporation of Generative Pre-trained Transformer (GPT) models provides customized suggestions for resume optimization, emphasizing areas of improvement indicated by the BERT study. Additionally, the application also has a job search tool that lets the users browse LinkedIn for suitable job posts and apply straight to them. The advantages of BERT over traditional keyword-based matching techniques are covered in this paper, including its ability to recognize the contextual relationships between words and phrases, providing matches that are more relevant and accurate. The proposed approach greatly improves candidate\'s chances of landing desired positions by enabling them to modify their resumes and facilitating a more efficient job application process. The incorporation of BERT\'s deep learning capabilities with GPT\'s generative recommendations signifies a significant progression in the career development technologies domain, offering theoretical and practical insights.

This project represents a turning point in the technological advancement of job market navigation, combining AI's analytical capabilities with user-friendly interface design to enable job seekers to navigate the complexities of the process with increased success, efficiency, and ease in the future.

II. RELATED WORK

More complex candidate selection processes are becoming the norm as a result of the recruitment industry's incorporation of machine learning (ML) and natural language processing (NLP). These cutting-edge tactics not only expedite the hiring process but also add a degree of accuracy that was not possible with conventional approaches. A fundamental study in this field demonstrated an innovative approach by utilising semantic features in resumes, obtaining a remarkable 92% accuracy rate in differentiating applicants according to these features. By putting analytical depth and accuracy first, this method dramatically outperforms traditional keyword-based analyses, demonstrating the potential of sophisticated algorithms to transform candidate selection [1].

Another study investigated the automation of resume screening with text mining techniques in order to solve the particular issues within the software engineering recruitment landscape. This study used techniques including resume summarising, information extraction, and ontology mapping to address the biases and inefficiencies of manual screening. The conversion of resumes into text files that can be analysed made it easier to evaluate candidates' qualifications in terms of education, work history, and abilities. The fact that this study was able to increase recruiting efficiency shows how important text mining is to the modernization of applicant screening procedures, particularly in the technical sectors [2].

One major step towards automating the screening process is the creation of the "Resume Screener" tool. This Python-based programme evaluates resumes in many formats using NLP and ML to precisely match candidate abilities with job requirements. This solution highlights the scalability, time efficiency, and reduced bias potential in recruiting procedures, addressing the issues of time consumption and biases associated with human screening. The "Resume Screener" is a scalable and objective method for candidate evaluation that serves as an example of the revolutionary power of integrating sophisticated analytical tools in recruitment [3].

A study that uses the BERT algorithm, which offers a sophisticated substitute for traditional word-matching algorithms, makes a significant contribution to resume categorization. This approach improves resume content interpretation through semantic analysis by preparing resumes and producing BERT embeddings. This study's notable gain in classification accuracy highlights the benefits of context-aware algorithms in offering a more thorough and accurate assessment of prospects, signalling a major advancement in recruiting technology [4]. The significance of technologies like Optical Character Recognition (OCR) and Named Entity Recognition (NER) in automating the recruitment process cannot be highlighted. A thorough analysis of these technologies covered their shortcomings as well as their innovations, emphasising how they have helped to streamline data extraction and document processing. The aforementioned analysis highlights the significance of these fundamental technologies in augmenting the efficacy and precision of candidate screening, hence promoting a more seamless integration of automated systems in the recruiting process [5]. Another study suggested an automated resume screening system that uses natural language processing (NLP) techniques to avoid the time-consuming manual resume analysing process. Using a dataset of about 1000 resumes, a neural network model was trained, and the system showed impressive accuracy in assigning resumes to various job roles. This accomplishment confirms that ML and NLP combined are effective in improving the resume screening process, offering a more accurate and efficient substitute for conventional screening techniques [6].

One significant advancement in e-recruitment is the creation of a comprehensive structure for analysing resumes and extracting structured data. This framework attempts to automate critical operations such as skill matching and resume parsing by utilising text extraction, categorization, NER, and skill ontology. This project, which aims to enhance the information extraction process and the overall efficiency of the recruiting cycle, emphasises the continued need for innovation in recruitment technologies [7].

Another study achieved great accuracy in job classification and suggestion by using an NLP-based methodology for both resume screening and job recommendation. This method, which includes gathering datasets, preprocessing them, and training models, is a prime example of how NLP may revolutionise the hiring process. It offers a practical and efficient way to automate important hiring duties, expediting the process of finding qualified applicants for open positions [8]. In order to improve talent acquisition strategies for businesses and streamline the job search process for candidates, a thorough resume analysis and position recommendation system has been implemented. This system evaluates candidates based on their competitiveness and suggests appropriate job openings by using machine learning and text mining techniques to analyse resumes. The efficacy of the system, as confirmed by an online survey, suggests that it has the potential to dramatically enhance the recruitment environment by providing a more individualised and effective method of job matching [9].

Finally, the use of ML algorithms for resume classification has made it possible to conduct the hiring process in a more organised manner. In order to accurately sort resumes by profession or field, this study used a variety of machine learning classifiers to analyse a heterogeneous dataset of resumes. The high accuracy attained by all classifiers demonstrates the potential of machine learning to expedite the hiring process and help businesses find qualified applicants more quickly across various industries [10].

To summarise, the inclusion of ML and NLP into the recruitment market represents a substantial advancement in candidate selection procedures. The highlighted studies and discoveries highlight the critical importance of these technologies in improving candidate selection, implying interesting future advances in the field. As technology advances, the potential for additional improvements in recruitment through ML and NLP remains enormous, ushering in a new era of efficiency and precision in the sector.
