Jeeves ERP interview questions

Worst interview experience I have ever had. Interview was scheduled by the third party consultant company, no intimation from the HR of the company which was quite strange. On reaching on interview date, was met by some manager. No written round or technical round. There was only one round; seemed like mixed of technical and managerial round. The interviewer was not prepared; he was not even expecting me it seemed. As he came, he hardly greeted and started searching for my resume in his system for 5 mins; yet it felt he dint find it and pretended looking at his screen. The interview completely seemed fake; that person seemed more interested in arguing then assessing the candidate. Never experienced such rude and unprofessional behavior from an interviewer before. The person bore such an unpleasant attitude; which i had to face for around 30-45 mins.
