It was more than one hour Technical interview , on asp.net, c# ,sql ,wcf etc , not sure what the interviewer will do with shallow copy & clone copy , had to explain him in detail to satisfy with my answer & why they don't get tired asking "what is the difference between Interface & Abstract class " Anyway after 1 hour 25 minute this phone screening was done & he moved to the next step for wasting more of my time ,now it was with HR , it was nice & quick almost 25 minute then for F2F i have been called with many instructions -take 5 copies of resume (as they can not do the copy of resume by their own , it is candidates headache ) Dress up nicely professionally blah blah . Ok then F2F now he asked me for - white boarding , the questions he was asking to challenge to a experienced candidate ,who was doing development from years -was for loop fibonacci number & all sort of questions which are online available ,only you have to see the tricks before appearing for the interview .They don't see that you know the concept , you know the syntax they are bookish ,just look into the internet example . So the intentions were to fail the candidate , so he failed me sweetly & saved his job for many more years in searching for the new candidate . If i am not the right candidate then how come i gave 100s of answers correct in the telephonic interview at the first step, it was all just to shake the confidence level of the candidate . I am afraid to whom these companies give the jobs, who takes white boarding ,online tests & tons of interviews , cant't they recognize the capability of a candidate in half hour asking technical questions or they do not have this ability to understand who is right or wrong candidate . And yes before telephonic interview i had been given two sheets to answer the questionnaires.
