I remember one story of SSB where a candidate told me. Someone he knew had listed Hockey as his hobby in PIQ form and during the interview, IO asked him if he knows the length of the hockey stick in exact centimeters. He didn’t know it. Obviously it was a negative on his side but at the end of the interview, IO asked him if he had any questions to ask. He asked him “ Sir, do you smoke? ” IO said ‘ yes ’ to which this guy asked him “ Do you know the length of the cigarette you smoke, in exact centimeters? ” , IO laughed.
The candidate was recommended but it suits his personality. The motive behind this story is that if you were unable to answer some questions doesn't mean your SSB went BAD, you can get back into it anytime.
