Interview Process

The interview process consisted of multiple stages. Initially, there was a phone screening with basic behavioral questions and a coding challenge. The onsite interview followed. In the onsite interview, I faced three technical interviews, each lasting about 45 minutes. The focus was mainly on data structures and algorithms. I was asked to solve problems related to arrays, strings, and dynamic programming. The interviewers were approachable and helped guide me through the problems.

Technical Questions

  1. Longest Substring Without Repeating Characters (Hash Table, Two Pointers, Sliding Window)

Tips & Insights

The behavioral questions revolved around teamwork and conflict resolution. One question I remember was, “Tell me about a time you faced a challenge while working on a team project.” Overall, it was a positive experience, and I felt the interviewers were genuinely interested in my thought process rather than just the final answer.
