as explained by many of the past reviews. the interviewer has pretty basic and limited knowledge. they have some textbook types of questions and if ur answer sud be exactly as textbook. if u add real life example which deviates from the text book answer, consider ur self disqualified. also questions are like its before 2010 and not 2024...so be ready to be surprised if asked something like what is this "specific standard" which in real life no one cares about as technology has "moved on" from that point.
