Interview Preparation Tips
The first round was a coding test, which was outsourced to an external vendor. I was asked 2 basic DSA questions, and there was discussions around the time and space complexity, and scope of optimizing the solutions. Post that there were a few questions around Spring Boot features and basic system design. The interviewer was professional throughout the interview, and the interview process felt more like a discussion, as compared to the standard interview process.
There was another round of coding - this time conducted by the organization itself. It consisted of a medium level DSA question on stacks. I wrote the code on my personal IDE and executed it there itself. The interviewer discussed about the possible edge cases and how I would deal with them. Post solving the question I was asked about my previous projects.
