Code Design Round: The question was something similar to the following: Let’s pretend we are in charge of a cinema. We want to figure out whether a new movie can be added to the existing schedule without removing any of the current movies. Note that: the cinema opens at 10:00 the last possible end time for a movie is 23:00 movie durations include setting up the room before the movie begins and cleaning it up afterward. In other words, if for example a movie ends at 14:00, the next movie can start at 14:00 movie start times are expressed in minutes starting from midnight, so for example, 10am would be 10*60 = 600

1st Interview: what is RAG why do we use it and metadata filtering. Fairly easy ones. Then asked me coding leetcode easy/medium level question on live coding. 2nd Interview:Design a recommendation system for a store when the input is an api with only userid. He then asked a medium/hard leetcode level coding question.
