This case study details my Razorpay on-campus assignment, where I designed a new feature: polling in WhatsApp groups. The goal was to enable users to ask questions and gather responses from group members. The assignment was completed within one day, including 4 hours for design and 2 hours for presentation preparation.

1. The primary user base is aged 18–25, followed by 26–35.
2. WhatsApp has provided a free alternative to SMS (Short Message Services), which is often three still a metered (pay per use) service.
3. WhatsApp often more cost-effective than SMS, but it facilitates extensive group conversations, something that is difficult through SMS, if not impossible.
4. It is used widely for both personal and professional use cases. Office groups, family groups, bussiness accounts etc.

To better understand user behavior, I focused on the primary age groups (18–25 and 26–35 years) and conducted interviews to explore key questions around usage, need of polls and other platforms.

Participants: I interviewed 8 students (18-23 age), 4 relatives (26–35 years), and my father (46 years, extensive WhatsApp user in the service sector).

Interview Questions:

1. Which app did they use the most for messaging daily?
2. For what purpose you use WhatsApp?
3. What are the top active groups in your WhatsApp?
4. Have you ever used the poll feature in messenger or facebook?
5. What question did you ask or answer?

• The poll is created and sent as a message on the group (similar to any other attachment uploaded by the user)
• After the user choose an option, the opted option will be sent as a reply to the poll, letting others know their opinion (Such multiple messages can be grouped to avoid spamming)
• The user can view the top two options, time left, the total number of options, and vote from the next screen.
• The result will be declared after every person in the group has voted or the time has expired.

My assignment was recognized as one of the top submissions, leading to further interview opportunities. This experience was highly valuable, particularly in managing a project within a constrained timeline. While several assumptions were made, I acknowledge that the final solution requires a deeper understanding of users and is not possible to do in a 4 hour window.
