Integral Development Senior Software Engineer interview questions

Interview has been scheduled through recruitment consultancy and it was very quick process. My interview was scheduled at 10 AM and the interviewer reached one hour late, and he was having some excuses for that as usual. I entered into office and felt like i am in old govt. revenue office, and i've seen CRT monitors are being used. Anyway my interview started with full energy with theoretical questions. No matter how strong you are in coding, interviewer expects similar answer what he knows. The funny part is he doesn't know what's Asymptotic notations and how time complexity get calculated for a given function. Within 5 mins i get to know that he doesn't know anything, and i didn't not replied any answer for his theoretical questions. Finally i understood that interviewer was too arrogant and he don't listen your answers if it din't match with his mugged up answers. He might have thought that he rejected me..but actually i rejected him that not to interview me anymore. So i didn't answer most of his theoretical questions. My suggestion is don't go here if you are a good programmer. I believe they don't know anything. No interview standard at all.
