Journey
I still remember starting out without even knowing the difference between HTML and CSS. Everything felt small but exciting—making a button change color or a simple form work gave me so much joy. I gradually learned JavaScript, built small projects, and later explored React to handle bigger ideas. The journey wasn’t always smooth. Bugs, errors, and confusing concepts tested my patience, but each challenge taught me something new. I learned to research, experiment, and ask for help when needed. Building small apps and solving real problems gave me confidence and a sense of growth. When it came to this job interview, I realized it wasn’t just about coding — it was about persistence, curiosity, and continuous learning. My journey taught me that consistent effort, even in small steps, eventually leads to meaningful opportunities.
Application story
The application journey began through our college placement portal, where I found the opening for this role. I submitted my resume and portfolio showcasing my projects and relevant skills. Shortly after, I received a call from the recruitment team for the initial screening. The process was well-structured and smooth; the company coordinated everything through emails and online platforms. I prepared thoroughly, focusing on my fundamentals and projects, and finally got the opportunity to attend the interview. Overall, it was a positive and motivating experience, and the structured process made it easy to showcase my skills effectively.
