1. 1

   Technical Round30 min

   This is ON-CAMPUS Interview Experience The interviewer was very helpful, supportive, and encouraging, which made the discussion smooth and comfortable He began by asking me to explain the complete flow of my project and a few related questions to check my understanding.

   During my introduction, I mentioned that I had solved 500+ DSA problems across various platforms. This led to several graph-related questions Toughest DSA Problem Solved: I discussed the Rotten Oranges problem, explained my approach, and why I found it challenging. Difference Between Graph and Linked List: Applications of Graph and Linked List: I gave examples like Facebook connections for graphs and browser back/forward buttons for linked lists. As a follow-up, since I said I like C++, he asked me to show how I would implement a Facebook-like functionality using graphs. I wrote a DFS traversal to demonstrate one connected component (like finding a friend circle). Although I could not complete the full code perfectly, I explained my logic using a dry run on paper, which the interviewer appreciated. (Tip: If your approach needs diagrams or dry runs, use pen and paper) Finally, he asked a few general questions like: My career goals My role models (and why they inspire me) To speak for about 5 minutes on current technologies like GPT, Cloud, etc., which I did confidently.
