Round 1: Phone Interview \n1) Binary Tree Level Order Traversal\n2) Binary Tree Zigziag Level Order Traversal\n3) Valid Palindrome (Array of Strings)\n\nRound 2: Phone Interview\nTechnical Discussion - Spark, Kafka (consumer groups, offsets, paritions, spark context, spark core engine, structured vs spark streaming)\n\nFinal Round: Onsite \nDay 1:\nRound 1: Design an alerting/monitoring system for Youtube\nRound 2: Given 2 intervals - find their union. Expand this to n intervals. Added a third parameter to intervals and asked to expand around center.\nRound 3: Design an IOT pipeline for collecting signals from devices worldwide.\nRound 4: OOD round - Design a game engine for a game of chess using classes and objects.\nRound 5: Design a self service scheme to be able to combine logs and present to other teams. Spark SQL - understanding and query creation.\nDay 2\nRound 6-8: Behavioral\n\nResult: Rejected. Messed up in the OOD design round. Felt half an hour was too less to come up with a feasible solution.
