   The interview revolved around Python programming and main Python constructs (Python OOPs, Decorators, Generators, GIL etc.). There were other questions that were related to basic SQL and some SQL vs NoSQL discussion. Then the discussion related to algorithmic implementations. I was asked to write Merge Sort in python (Long code !!!). Then for the follow-up, interviewer asked me to derive the time complexity of Merge Sort and some other use cases related to Merge Sort. Then the topic was some basic GIT commands and a use case to explain the flow of code sharing and version control. Then the discussion was to explain some Cloud related concepts (S3, ECS, Lambdas, Lifecycle Policy etc.). At the last, I was asked a puzzle Link: Puzzle ( Rs 500 Note Puzzle )
