Round 4 (Last Round HR+tech)

I was called for Round 4 after an extended list of shortlisted candidates. Was a little nervous because my interview was the last in the whole college. And got insight from other candidates that the interviewer was asking about cloud computing. I had never worked in microservices in college but have little knowledge.
And my name was called so I entered the room.
Still 2 panellists but a different pair than before.
I greeted them with “Good Evening” and the interview began.

1. They asked me what is cloud computing.
   I was relieved that ok I could answer this.
2. Then he asked me about what I liked in United Airlines.
   At that time I was studying the history of United Airlines for 2 days as I was focusing on getting into this company. I told him how United Airlines was formed. What tech does it use? Where are backups? How does it handle disasters?
   Like everything I know. Even the interviewer was confused about how I knew about all this info. He replied I even don’t know this much.
3. Closing the interview he asked me to “Any Question”?
   At that time I had many questions. I asked about 2 questions and the interview was over.

I would like to share my United Airlines Interview Round Experience
Just to give a basic summary the job role was Software Developer. It was an on-campus Interview experience.
