ABSTRACT:
The Placement Cell is an interactive web-based
application. The main purpose of the application is to
facilitate the process of placement for students. It is
designed specifically for use in colleges. The web
application is developed to offer three separate modules:
the user module, the company module, and the admin
module.
User modules are specially designed for interested stude
nts in participating in the placement drives. The students
can register on the platform and provide all their
necessary details, such as personal information,
academic records, and other relevant details that are
required by the placement cell. The module is equipped
with essential features to enable students to upload their
resumes, browse through the available placement drives,
apply for them, and track their application status. In the
company module, various companies visiting the college
can view a list of students and their respective resumes.
The company module has ability to add job titles, job
descriptions, drive dates, etc. The admin module is
designed for the college administration and staff who are
responsible for managing the placement cell. The admin
module allows them to upload details about upcoming
and ongoing placements, manage student applications,
and generate reports. One of the core features of the
admin module is the ability to view the
details of students applying for placement drives. The
Placement Cell is a valuable tool for both students and
college administration. The platform offers an effective
way of managing and tracking the placement process,
thus ensuring that students get maximum benefit from
the available placement opportunities. The development
of the Placement Cell aligns with our commitment to
provide innovative solutions that enhance the learning
experience of students.
Keywords: Placement Cell, Interactive web-based
application, College Administration, Upcoming and
Ongoing Placements.
1. INTRODUCTION:
The Campus Recruitment System is a comprehensive
software solution designed to streamline the recruitment
process within a college campus. It offers three distinct
user roles: students, companies and administrators, each
with specific functionalities and benefits.
For students, the system provides a user-friendly login
interface where each student can create and manage
their profiles. Students can input their academic details,
including marks and other related information. This
centralized repository simplifies the application process
for various job opportunities.
Admins play a vital role in maintaining the system's
integrity. They have the authority to review and approve
student profiles while also removing any inaccurate or
faulty accounts. Admins also oversee the entire system,
ensuring that it complies with college placement rules.
The company login feature allows visiting companies to
access a list of students attending the college also view
their resumes. This functionality streamlines the
recruitment process for companies, making easier for
them to identify potential candidates.
Furthermore, students can explore a bunch of companies
that have posted job vacancies through the system. This
feature empowers students by enabling them with
insights into available job opportunities and the

companies recruiting on campus. The system also
includes email and for faculty members and students.
Admin members are informed about job postings
relevant to their department, ensuring that students
receive timely updates on job profiles.
Ultimately, the Campus Recruitment System is a web-
based software solution that enhances placement
activities within the college. It facilitates communication
among admins, faculty, and students. Key features
include user management, job posting, tracking company
data, and notifications. The system is customizable to
meet the particular needs of each college, enhancing
efficiency and overall placement performance.
2. LITERATURE SURVEY:
The primary and crucial phase within the software
development process involves conducting a
comprehensive literature review. During this phase, we
delve into the preliminary research conducted by various
authors in the relevant field. By carefully analysing and
considering significant articles, we aim to build upon the
existing body of knowledge and expand our work further.
The need for online job boards for universities, along
with their usefulness in bridging the gap between college
students and employment chances. Employment
websites have historically been utilized in HR
administration for recruiting and finding candidates.
This work is mostly based on a job portal created for
Pulchowk Campus, one of Nepal's top engineering
colleges. It is a special version of a job board created for
the campus's students. The system is supposed to be
useful for both students looking for jobs and businesses
looking for possible candidates suited for the position.
Services like job recommendations to students based on
their talents and applicant filtering to assist employers in
candidate matching.[1]
A website that offers online information to recruiters
and job searchers is known as a job portal. By taking into
account their tastes, education, and experience, it aids
job searchers in finding the best organizations. A list of
businesses that meet the job seeker's requirements is
displayed on the portal.[2] Similar to that, it offers
recruiters a pool of qualified individuals to pick from.
The main purpose of this application is building a
platform that facilitates efficient communication
between potential candidates and companies.
In order to enhance the efficacy of campus recruitment
fairs, a quantitative evaluation system has been
proposed that analyses the big data statistics of such
fairs.[3] By combining an effective statistical analysis
model with a sample regression analysis method, the
system evaluates the data gathered from campus
recruitment meetings and formulates a decision
objective function to assess the impact of the campus
recruitment fair. The system also employs a convergence
rule evaluation method for quantitative regression
analysis of the fair's effectiveness. The outcomes of this
analysis are derived by mining descriptive statistical
data and relevant descriptions from the big data
collected.
This article delves into the traditional way of
recruitment by reviewing its background. It further
highlights the emergence of new recruitment methods,
such as e-recruiting, and evaluates their effectiveness.
The advantages of e-recruiting, including its accessibility,
are discussed with its disadvantages, such as the
violation of some legislation.[4] Moreover, the article
explores the impact of e-recruiting on management. The
study conducted face-to-face interviews with 102
companies from the population.
This project aims to implement a Desktop Based System
for Campus Recruitment using Mahout. It can help
college placement offices to match the company's criteria
with students' eligibility. Th e system automates the
activities of placement cells in colleges, reducing the
dependence of human intervention. Our main focus is on
profile matching, where eligible candidates all will be
matched with the company's criteria. To achieve this, we
will use Mahout's Naïve Bayes Classification algorithm.
Based upon profile similarity degree, the preference lists
of companies and students are calculated, which serve as
the input of two-sided matching.[5] With the new system
embedding SMS-based interaction, it can raise the
matching degree, shorten the recruiting period, and
reduce costs. Furthermore, this recommendation service
is not only applicable in the region of campus
recruitment but also provides a frame work for the
mobile business field with the extension to other
domains such as hospital-intern and college-student
matching and recommendation.
The study's goal was to create online hiring tools that
would make it easier to fastly and approximately choose
qualified candidates. The software was developed using
the Modified Waterfall Model.[6] System efficiency
in terms of performance, dependability, security, and
cost-effectiveness was then assessed using the generated
software by six sets of respondents. Descriptive statistics
demonstrated the utility of the software.
Lack of user management data across distinct
application systems causes users to maintain multiple
sets of accounts and passwords, despite the fact that
each system must provide the user interface in order to
function; absence of unified authentication users are
unable to use different apps and information resources
in the campus network via a unified entrance due to lack
of services and adequate management. In order to close
the "gap" in the application system, integrate different

types of data and workflow, and ultimately provide a
personalized platform to obtain and disseminate
information uniformly, campus portal, a unified public
network application platform, is required.[7]
Using an applied web concept, this project seeks to
improve the design and development of HR apps by
providing a productive and innovative communication
platform. Application design follows two basic principles
of responsive and dynamic web architecture.[8] The
portal provides candidates with an easy-to-understand
application process and career information with an
optimal reading experience on all devices thanks to a
responsive web interface. The dynamic communication-
path structure of the backend system allows seasonal
employees to develop business skills that efficiently use
project information and common operating procedures
An ontology model of job description is presented in this
paper. This approach helps employers create better job
descriptions and provides a structured, computer-
understood framework for job descriptions.[9] The most
important advantage is that it provides a workflow for
editing job descriptions and cross-posting them in a
common conceptual framework.
This project proposes development of an automated
multi-levelled online recruitment system that first uses
techniques to analyse and extract lists of candidate
concepts from the job postings and user resumes the
next step is semantic search existing resources (also
called ontologies) must be incorporated in the workflow
and then computationally based conceptual-relational
techniques are used for dealing with the situation when
the logical resources used do not recognize a
concept.[10]
All college student’s data can be gathered, and we can
retrieve them in accordance based on company's criteria.
The three modules we have Student, Company,
Administrative/Training and Placement Officer (TPO). It
also ensures that admin with full access. Students will
mostly move their CVs, while administrators, TPOs, and
companies may also transfer resources. The company
will register and disclose their placement criteria.[11]
Our suggested system must be implemented in colleges
to improve placement services.
Web pages are made more machine-understandable by
semantic web, making them readable by both human and
artificial agents. Software agents have the capability to
browse and process Web pages.[12] The motto of web-
based educational systems is improved by semantic web,
which also raises the standard of learning. According to
Mizoguchi, "it can give students personalized learning
materials, gather data about how students interact with
the web environment, and discover services."
One of these services with a potential market in China is
the SMS-based mobile recommendation system for
college recruitment. Our survey and interviews with
college placement offices revealed that the relatively
lower matching degree (such as information overload or
ambiguity), longer recruitment period, and greater
expense of the present campus recruiting systems have
been frequently criticized. In a nutshell, there are four
causes of those issues. First, the HR released vague and
unclear requirement descriptions, which caused a larger
variety of requirements and miscommunication among
job candidates. Second, candidates who lack crucial
career planning or are unable to fully comprehend the
job description might submit their applications for the
wrong roles. [13] Thirdly, the phenomena where job
searchers who are under more pressure to find work
apply for numerous openings in a mass and random
manner would raise cost of applicant selection.
Additionally, the China's university hiring events take
place in October and November, which overworks the
employees. The candidates may be chosen at random in
this scenario, which results in poorer matching.
3. PROPOSED WORK:
3.1. Problem Statement:
All Processes in the previous existing system are handled
manually, resulting in a heavy workload for the
placement Officer and increasing the risk of errors. Due
to the sharp increase in the number of users, the process
has become more difficult. Some of the
problems/obstacles faced in the existing system are
 Searching for eligible students is done manually
by the TPO based upon company criteria.
 The records are stored in modified Excel sheets,
resulting in sorting problems. Data redundancy
due to duplication of records.
 TPOs have to collect and organize information
and resumes of students according to various
streams, which is a time-consuming task.
 Managing, updating, and informing specific
students for specific company criteria takes too
much time.
3.2. Proposed System
The planned Web-based Training and Placement portal's
major goal is to make it easier for TPOs, placement
coordinators, and students to access and edit
information. The technology offers a better approach to
maintaining student data in the database, maintains data
integrity and accuracy, and shortens the time required
for paperwork. There will be no need of putting up
notice or emailing every student about the companies
visiting the college. The students can keep updated
themselves through this software. The company can

view all students data and it can shortlist students based
on their criteria instead of doing manually. Student can
register online instead of going to placement department
for registration. The three main elements of our web
portal are student login, admin login, and company login.
Student Module:
A crucial element of a campus recruitment system that
assist students with their job search and the hiring
process is a student module. This module often forms a
portion of a broader platform or piece of software for
campus recruitment that universities, colleges, or other
organizations use to run their career services and assist
students in finding potential employers. The following
are some essential characteristics and features
frequently present in a student module within a campus
recruitment system.
Profile Creation: Student profiles can be created and
updated with personal information, academic
accomplishments, talents, and by uploading resumes.
Job Search and Apply: Employers or organizations
taking role in the campus recruitment program may post
job openings, internships, or co-op opportunities that
students can view for and apply for those jobs.
Student Application Submission: Students can submit
their cover letters and resumes for employment
applications through the website. They might be able to
follow the progress of their applications as well.
Communication: The career services office or
partnering employers may send relevant alerts,
messages, or announcements to students. If students
have any doubts, they can easily contact the admins
through emails.
Preparation Material: Access to tools including
interview guidance, job search recommendations, career
guides, and company profiles to aid students in their job
search preparation.
Admin Module:
The administrator's role is essential for a campus
recruitment system to function effectively and efficiently.
Managing users: Administrators have the ability to
create, alter, or deactivate user accounts for students,
faculty, and other administrators. They can also assign
roles and permissions.
Job Posting Review: Before making job posts or
internship possibilities available to students,
administrators can examine, approve, or reject job
postings or internship submissions from companies.
Placement Reports: TPO can assess the ratio of
students who were placed and make comparisons with
comparable placements. The user performance statistics
will be provided by this module.TPO can assist the
students in improving their performance using this
automatically generated information. To generate
information on placements, this module will handle the
data of job seekers and cut down on the paperwork
required of TPOs.
Detecting fake Accounts: TPO can evaluate
performance using prior years or data to comprehend
student needs. It will allow access to the system and has
the ability to delete fake accounts.
Company Module:
The "Company" module, which contains all the features
related to the organizations taking part in the selection
process, is essential to a campus recruitment system.
This module offers details about the numerous groups
that are recruiting on campus and is primarily utilized by
administrators, recruiters, and students.
Benefits and Outcomes:
There will be no need of putting up notice or emailing
every student about which company will be coming to
college. The students can keep updated themselves
through the software. The company can see all student’s
data and system can select students according to their
criteria instead of coding manually There is admin login
that can view and manage both students and company’s
account and can put up notifications. Student can
register online instead of going to placement department
for registration. This system saves time and efforts.

3.3. Methodology
1.Data Collection:
Gather information about students and placement
drives, including student details, academic records,
placement drive details, and job requirements Collect
data on students' academic performance, skills, and
other relevant information.
2.Feature Engineering
Create features that represent student qualifications and
suitability for placement drives. These features can
include academic performance, skills, extracurricular
activities, and other relevant attributes. Calculate
distance-based features using K-Means Clustering to
group students with similar profiles.
3.Labelling
Label students based on their suitability for specific
placement drives. For instance, label students as "1" if
they are well suitable for a particular job and "0" if not.
4.Naive Bayes Classification
Train a Naïve Bayes classifier using labelled data to
predict student suitability for various placement drives
and utilize the classifier's probability estimates to match
students with job opportunities that suits with their
qualifications and preferences.

5.K-Means Clustering for Student Grouping
Apply K-Means Clustering to group students with similar
academic and skill profiles and use the clusters to
recommend placement drives to groups of students with
similar qualifications or career goals.
√( ) ( ) ( )
6. Placement Drive Prediction:
Based on Naïve Bayes and K-Means results, match
students with suitable placement opportunities. Students
within the same cluster can be offered similar placement
opportunities based on their qualifications and interests.
7. Admin Interface:
Create an admin interface that allows placement
coordinators to manage placement drives.
Administrators can view available placement drives,
student applications, and the recommended matches.
8. Student Application Management:
Implement a system for students to apply for placement
drives. This can include uploading resumes, cover letters,
and other relevant documents.
9. Placement Drive Management:
Admins can create and manage placement drives, setting
criteria for student eligibility.
10. Validation and Reporting:
Develop validation rules based on Naïve Bayes and K-
Means results to ensure that students are matched with
suitable placement opportunities and generate reports
on the success of placement drives and the suitability of
students for different job profiles.
Benefits of Using Naïve Bayes and K-Means:
Naive Bayes: The classifier helps match students with
suitable placement opportunities based on the
probability of their qualifications aligning with job
requirements.
K-Means Clustering: It enables grouping students with
similar profiles and interests, improving the
personalization of placement recommendations.
Optimization: Using both algorithms can optimize the
matching process, ensuring that students are
recommended for the most suitable placement drives
based on both qualifications and preferences.

5.CONCLUSION:
In conclusion, the majority portion of work is done
manually in the current placement system, and system
changes take time. The search, sorting, and updating of
student data provide a significant challenge, and the only
available notification method for students is the notice
board. The suggested system automates online user
registration for each user, user activation and
deactivation, personalization for each user, online
resource provision, user interaction, and online
feedback. The administrator can view user information,
verify it, and create a student list based on company
criteria. The user can
FUTURE SCOPE
1. Consideration of Current System and
Acknowledgment of Improvements:
Recognition that there is room for improvement
in certain areas, along with an acceptance of the
system's drawbacks.
2. Proposed System Enhancements and
Expansion: Suggestion to integrate the Exam
cell of the college with the system to remove the
need for two separate systems and facilitate
double verification of marks and other
important data.
3. Incorporating Multimedia Elements: Mention
of the possibility to include videos of students or
companies within the system, likely for
educational or promotional purposes.
4. Adaptability and Ongoing Development: A
commitment to align the software with changing

requirements to keep it relevant and effective in
the future.
