First Bank, Can some1 tell me why i was not invited for the aptitude test?

please can any one tell me why first Bank has refused to call me for their aptitude test?I applied for my sister,she was invited and i was not.could it be as a result of age?cos i registered 1979 and my sister 1980.We both have the same Qualification.The annoying of all is that this is my 3rd time of applying and has always not been invited.Infact am no longer intererstd in their bank again.

Guy sorry 4 what first bank did but since u have applied twice before this and all u get is we got ur application but they couldnot process it, u should have dat they us age as the criteria.
Must people l know including me reduced my age to 1981 bcos when l used my normal age 1979, they turned my application.
So l suggest incase of next time,u adjust bcos almost all banks needs a minimum of 27years

i think its because of the age limit.
