Journey
I started coding in the first year of my college because all my friends were doing it. Initially, I learned C++ from a YouTube course, but later, one of my friends took the Coding Ninjas C++ DSA course. Based on his review, I also purchased the course. Over the next 12 months, it built my foundation in C++. I then started solving coding problems and practicing DSA questions from the course. In my third year, I enrolled in another Coding Ninjas course on MERN stack development, from basics to advanced. It was my first experience with web development, and I created some really good full-stack projects. This course strengthened my fundamentals in React and Node.js and gave me hands-on experience in building real-world projects. Finally, in my placement year, while searching for internships, I came across a hiring drive in Noida, Sector 62. I went there well-prepared, the interviews went smoothly, and I eventually landed a job in my 8th semester.
Application story
I saw a hiring drive post on LinkedIn, then wrote a cold email to the HR and founders of the organization, and received an interview call.

Tip
Tip

Tip 1: Be consistent and track the days you actually coded.
Tip 2: In web development, implement whatever you learn. Create mini projects for smaller concepts, and eventually build a full-stack application.
Tip 3: Practice DSA consistently throughout your journey. You can learn anything (e.g., Web Development, AIML, etc.), but never stop solving DSA questions on coding platforms.
