I had applied at SBSB in the month of April, finally got an interview call in May. The interview process had 4 rounds, 3 rounds technical and 1 ‘AA’ round. 2 rounds were conducted on the same day and remaining 2 on another day.
- 1 Leetcode question: Dynamic Programming
- Word Break problem of leetcode medium level.
- LLD question to design an technical discussion forum.
Round 2: HLD question on system design and implementation. Here they had taken a problem statement of their own project and asked me to implement. It was for basically aggregating stats from multiple sources and design a scalable, secure and fault tolerant system. Here focus on asking right questions to interviewer for first 15 minutes, which will define on how the round will progress.
Round 3: This was a combination of behavioral and a coding round. Coding round was for writing a code to parse a 10TB of file and filter some parameters from it. Was able to just explain and write pseudo code for algorithm but couldn’t complete the entire coding.
Round 4: This was a round with a senior director and it was more of a behavioral round with one coding question. Needed to insert an element into a sorted circular linkedlist. Somehow I was not able to focus in the question in this round and it didn’t go pretty well.
