Tekion DSA round | 7.5 yrs experience
Summary
I recently went through a challenging Data Structures and Algorithms interview round at Tekion, where I was presented with two difficult LeetCode problems. Despite effectively solving both, I ultimately received a rejection.
Full Experience
I had an interview with Tekion for a DSA round. I was asked two questions. The first was Trapping Rain Water. I was able to solve this problem and explain my approach thoroughly, demonstrating a deep understanding of the core concepts. The second question was Find the K-th Character in String Game II. For this problem, I devised and implemented the correct solution. However, I made a small error, using < instead of <= in a comparison, which led to incorrect results. I was actively debugging the issue, but the interviewer stopped me at the 55-minute mark. I mentioned that I believed my solution was very close, and I later confirmed the comparison mistake using an LLM. After calling HR, I received notification of my rejection. I found the interviewer uncollaborative, and it was difficult to get any acknowledgment or feedback. It felt like they deliberately gave me a hard second question. I'm left wondering what more one needs to do to successfully clear such a round.
Interview Questions (2)
This problem typically involves a string transformation game where an initial string undergoes iterative modifications. You are given an initial string and an integer k, and the goal is to determine the k-th character of the string after a specified number of operations or at a particular point in the game's evolution.
