The interviewer informed me that this round would consist of two parts: the first half would focus on Leadership Principles (LP), and the second half would be a coding challenge. The LP round went well, and soon, I moved on to the coding part. The problem was similar to detecting a cycle in a graph. I began by explaining my approach, thinking out loud. To my surprise, the interviewer asked me to code the entire solution first and review it later. This caught me off guard, and for a moment, I felt unsettled. When I finally started coding, my mind went blank. However, I decided to take small steps and began coding the parts I was confident about. Gradually, I managed to piece together an almost correct solution. Next, I started the dry run. After testing the code with basic cases, I was convinced it was correct. But then, the interviewer introduced a test case that was completely unexpected—and my solution failed.
