Why did the client choose us?
Our previous joint effort boosted their decision to trust us because we had the skill and ability to adequately cater to their needs. They also required integration with their communication provider, Telecom Provider, to ensure the cost-efficient and reliable delivery of messages through WhatsApp. From the technological angle, we were the right professionals to implement this integration efficiently, which made the chatbot work in its operational procedures.
Process overview
We used an iterative development approach, where we slowly progressed through building and implementing different parts of the chatbot. Through this platform, the client could test the functionality early on, make the necessary adjustments without significant rework, and adjust the system to their business needs.

Challenges we faced and how we overcame them

Limitations of Telecom Provider
solution
The communication provider did not support the specific functionalities we required, so we constantly contacted their technical support department. Together, we found ways to get the rebounded and the add-ons needed to achieve sustainable operating conditions on the WhatsApp chatbot.
Limitations of WhatsApp API
solution
WhatsApp's API does not mark incoming messages based on the context of the conversation, making it challenging to track ongoing dialogues. To overcome this, we implemented a solution that identified messages by the sender's phone number, which allowed us to accurately track and associate messages with the appropriate conversation flow.
Key security measures
To ensure data security, the following measures were implemented:

Protection against SQL injections
Input validation, along with parameterized queries, was the option that helped prevent unsolicited database manipulations.

SSRF attack filters
Inbound data is scrubbed with a specific sanitizer. It was to supply the patch to deal with the possible server-side request forgery vulnerabilities.

Integration of third-party systems
An integration with Telecom Provider was necessary to access the data provided by the prospects through WhatsApp. We were compelled to use Telecom as the third-party application because WhatsApp forbids direct message transmission. This, in turn, the integration made the message-sending process correctly handled.
It allowed us to create automated interactions with the candidate, and sending and receiving messages can be easily tracked within the system. Furthermore, we collaborated closely with Telecom technical support to harmonize the integration with the client’s business requirements.
Features
Candidate Registration for Job Vacancies
Candidates can directly apply for open positions through WhatsApp by answering a series of predefined questions about their experience and availability.
Automated Interview Scheduling
The bot aids candidates in picking a suitable interview time by providing open slots and granting approvals for appointments.
Meeting Reminders
Automated reminders are sent to let the candidates know about the days of the interviews ahead to reduce absenteeism.
Post-Interview Feedback Collection
After the interview, the chatbot s candidates to provide feedback, which HR managers can review to improve the process.
Training Reminders
The bot informs the candidates of the forthcoming training sessions in the company's internal learning platform if a candidate is hired.
Training Feedback and Recommendations
After the training, the robot follows up with the collected feedback and sends useful proposals to store managers to enhance future meetings.
Employment Document Submission Reminders
Candidates who pass the hiring process receive reminders to submit the necessary employment documents to complete their onboarding.
Project results
The final product is an operational WhatsApp chatbot that can take over the work for HR managers. Its purpose is to lower workloads, automatically register potential candidates, schedule interviews, and remind them automatically. The AI system even gets feedback from the candidates once they get through interviews or training sessions, which supports the hiring and onboarding process. Furthermore, a bot s new personnel to provide the required employment documents, and thus, HR departments become more efficient in handling administrative tasks.
