Oracle Senior DevOps Engineer interview questions

I applied online via Linkedin. I received call from HR in couple of days. I was called for F2F interview on Saturday. Interview process took 1 + week. There were 3 questions related to shell scripting. I solved them but interviewer left after 10minutes. After sometime HR came and he told me to keep the papers at his desk when i am done. Summary: 1) Poorly managed by HR/interviewer - i was told that there will be couple of technical rounds. But there was just 1 technical test and interviewer did not ask me to explain the logic 2) No update from HR - after sending couple of mails i received mail saying feedback is not positive 3)Seems interviewer is only interested in "google" answers to qns he asked - i cross verified the logic of all 3 shell scripting qns and it was correct (apart from some syntax errorrs)
