The interview was more than 4 hours without any pauses and if you know someone who works there , he/she can share with you the whole interview and memorize it and answer the 40 pages well as the interview is same for many position and hasn't been changed for many years ,this is what i have known after i finished the interview so they didn't test your knowledge they test your memory. the interviewer doesn't respect qualifications and my experience and the another interviewer talked with me in a such rude way and trying to make me fail not trying even to understand my answers !!! after this long interview i haven't even received any email about my status.
