About Shortlist
Shortlist is a web portal that combines technology and human screening to find outstanding talent for businesses. It provides organizations with top qualified candidates based on the skills and attributes they demonstrate via in-depth performance analysis.
With world class resources at their disposal, Shortlist discovers, evaluates, informs and places talent across variety of industries. Candidates take online assessments to highlight their professional potential and based on that, they get matched with the right opportunity.

Challenges in Version 1

The previous version was mainly focused on testing the idea and it’s technical feasibility. But considering the scope and growth of the business, it was clear that we needed a major upgrade to the portal. The MVP needed a fix in various departments including Frontend and backend technologies, UI/UX, Performance and overall business model.
So we decided to map out ‘Version 2’ which will be more focused on achieving strict targets in terms of number of new sign ups and revenue generation. To achieve this, we did some major upgrades to the portal which resulted in achieving the targets from the first month itself, let’s decipher the magic step by step.

Major Upgrades Done

Technical Upgrades

We did major technological upgrades to the portal including replacing old protocols with the new ones and adding latest tech features.

UI Upgrades

We revamped the corporate website in major ways to make it more appealing to users with superior ‘User Experience’.

Assessment Upgrades

The screening process was fully automated while eliminating the manual work. Candidates get real time score and report.

Performance Upgrades

Greatly improved page load time from 200 candidates/3 seconds to 1000 candidates/second.

The Transformation Process

In Version1, we were relying on Java, Spring, Hibernate, Angular1 and Apache CXF. While in Version2, we replaced Angular1 by the recently introduced Angular2, added Spring Cloud to Spring technology, integrated Spring Data JPA and used Spring REST Services. These all constituted a major technology upgrade.
We also took an important decision to move from Monolithic design pattern to a Microservice Architecture. The idea was to divide the single application into multiple interconnected applications.  Why? Well, a microservice architecture design pattern has many advantages over a monolithic design pattern including Scalability, Availability, Faster and more continuous Service deployment, Technology diversity, much better performance and above all, cost effectiveness.

Upgrades in Screening Process

We also launched a dedicated operations portal to manage candidate screening life-cycle. We defined ‘15 Days’ as a duration to close the complete screening process. Candidate will receive an email along with the progress report and feedback at each stage including whether their application has been accepted or rejected, whether they are qualified or disqualified for further screening and their final selection.
The assessment will also be evaluated in real time and the result will be communicated immediately along with the comment. For example, ‘You couldn’t move ahead because you are overqualified for this position’.
If a candidate is qualified, then he/she is automatically redirected to the next assessment.
This automation resulted in huge time, cost and resource savings for the company. Not just that but the overall user experience throughout the screening process has also been improved by great extent.
Upon completion of the application process, candidate will be prompted to complete the personal profile and take assessments

Assessments

Previously, all assessments used to be carried out internally. This task is now assigned to a company that expertises in online assessments named ‘Interviewed’. The move helped Shortlist to focus on foundational activities and delegate the manual tasks to the specialised organisation, also freeing valuable time and resources.
Psychometric  Tests used to be conducted on third party software portal named ‘Mettl’. The decision was made to develop a fully functional automated tool similar to ‘Mettl’ and integrate it with Shortlist for Psychometric assessments. This helped to establish more control over the tests and make frequent updates from time to time.
New Assessment

Performance Upgrades

Version1 was lagging behind the competition when it comes to ‘Page Load Time’ and Loading time of candidates count. Previously it used to take 3-4 seconds to load a page with 200-300 candidate list. So we worked on this by streamlining the processes and replacing unwarranted ones with those which will help boost the loading speed and server communication. With the updations done, now it only takes 1-2 seconds to load the list of 1000 candidates. And the result is not just limited to candidate names but it also includes all the major fields and filters.

UI/UX Upgrades

We revamped the corporate website in major ways to make it more appealing to users with superior ‘User Experience’. We started with making the application process more interesting and exciting for candidates. We introduced Chat based application process where candidate will be interacting with a Chatbot. The bot is backed by AI / Machine Learning which is capable of formulating questions based on answers given by the candidate in previous question like ‘What’s your full name?’, ‘What’s your mobile number?’, ‘Where do you live currently? ’,‘Would you be willing to relocate to New York for this opportunity?’ and so no.
In order to incorporate new functionalities swiftly, we used ‘Web Sockets’, which are very thin, lightweight layer above TCP. They make it very suitable to use “subprotocols” to embed messages.
