One of the most unstructured way of an interview, they took half hr to recognize me that weather my interview is scheduled or not, after confirmation interview was taken by them, duration on interview was approx 1.5 hrs, he asked most of the things which should be asked but was seeking answer which is same as he was able to see in his laptop, come on guys if you do not have qualified person to take interview than have some contract with recruitment agencies they will hire for you, asking question by surfing and expecting same answer is worst way of interview. More of that it took him 1.5 hr to reject me in interview.
