Nuance interview questions

I would say worst process, called in for F2f interview but the panel was there for 1 hour. Acceptable as there could be traffic problems., but after that the panel started asking questions to which I gave the answers correctly (cross checked after the interview). But the interviewer was not convinced as he did not have python knowledge. He only wanted the answers which Google displayed. Cleared 2 technical rounds then managerial round... But after managerial round another guy comes in the room and start asking questions and start arguing on stuffs on which he is having less knowledge. I checked his profile on LinkedIn as well and found that he is having just 3 years of experience, with just half in python and automation rest was in manual. I mean how can you ask him to take the interview. After all this, HR asked me to leave for the day and after many follow up they told me my position is on hold. Nuance team... You need to be professional..
