Round by round

1. 1

   Online Assessment60 min

   The first round consisted of three coding problems: Two-Pointer Problem – Required efficient handling of a sorted array using the two-pointer approach. Priority Queue Problem – Focused on implementing a solution using heaps or priority queues. Sieve of Eratosthenes – Classic prime number generation problem, emphasizing efficient mathematical computation. The OA was straightforward but required strong problem-solving skills and optimal implementations. After about 20 days, I received an email inviting me to the next round.

   • Two-Pointer Problem
   • Priority Queue Problem
   • Sieve of Eratosthenes
2. 2

   Technical Round60 min

   This round was quite unique. I was given a scenario where I needed to provide the necessary inputs based on a problem statement. After this, the interviewer provided me with a pre-written code snippet containing logical and syntactical errors. My task was to debug and fix the code within a given time. The focus was on understanding existing code quickly and making necessary corrections efficiently. The next day, I received an email informing me that I had cleared this round and would have Rounds 3 and 4 on the same day.

   Managerial Interview60 min

   This was a discussion-heavy round with a manager. The focus was on: Team collaboration and problem-solving skills – Situations where I worked in a team and resolved conflicts. Project discussions – Walked through my past projects, especially those involving complex problem-solving and large-scale systems. Decision-making – How I approach challenges in projects and make technical decisions. The questions were quite similar to standard HR behavioral questions but with a technical and managerial perspective. Questions:

   • Team collaboration and problem-solving skills
   • Projetcs Related
