Akamai Interview for Big Data/Hadoop interview questions

First i had technical round which went nice and i was able to answer all questions. Second round was with SA level guy, He asked me normal high level questions about SPARK and HIVE, nothing in depth. last round was with Manager which was related to normal work life, all answers were replied properly. But manager seems to very arrogant, was not having even basic netiquettes to take a call and was rude while asking questions (if it is required to repeat). Initially HR guy was in hurry to arrange calls but even after clearing 2 technical rounds, didn't receive any further update. There was nothing which i could not answer, later on i realized that this interview was just a show-off biz to show to that management that they tried finding resource outside so that they can hire their referrals.
