Round by round

  1. 1

    Coding Round (DSA)60 min

    interviewer started with a quick discussion about my background, work experience, and tech stacks. After getting a brief overview, he quickly jumped into the coding questions. Problem one: Longest Substring With At Most K Distinct Characters

    • Approach: I used the sliding window technique with a hashmap to track character frequencies.I coded it up, explained my thought process, and the interviewer was satisfied with both approach and implementation. Problem two: Maximum Sum Combination At first glance, I panicked a little but stayed calm, the interviewer provided helpful hints, allowing me to brainstorm the solution systematically. I identified the backtracking logic, laid out the base cases, and started implementing the solution.While I was able to write a working base solution, I could not optimize it fully, which was ultimately the reason I got rejected.
