Medatech Project Manager interview questions

the interviewer was very meticulous, and took an 'i'm nasty' attitude. very weird. despite the treatment, he asked relevant questions from several areas such as data structure, SQL, and logic riddles

I came to the company for a professional interview. In the interview questions were asked about material in accounting, java programming, after this the interviewer told a story about small shop and i needed to write ERD about it. The atmosphere was harsh and unpleasant.
