Sabre Senior Operations Research interview questions

In both interviews they asked some random case studies. I presumed they were at managerial positions with no hands on expertise. They just know the terms. Very easily, and confidently I talked rubbish using the same jargons mixed with intermittent clustering, classification etc etc. Nobody on either side of the phone or F2F had any clue what was being discussed. Just be confident. Anyways, in regular work you just need to do data cleaning or some hopeless coding in the role.
