Hortonworks Technical Support Engineer(Linux) interview questions

Noticed my profile on Linkedin, contacted me and the 5 round interview process was initiated. 1st round was with the recruiter, which went fine. Second round was with a senior recruiter, which was also fine. After the third round everything went downhill. 3rd round was with a tech support guy, who asked me all kinds of technical and personality type questions. 4th and 5th rounds were way too technical. After 2 weeks got the replay saying I wasnt fit for the job.
