what world do you live in buddiman ???only attending the interviews ain't gonna get you job.you need to have that talent and confidence on you.no matter if you graduate from harvard if u dont have the skills the employers r looking for, ur certificate ain't shit.
go to a good college and no skills on your hand .u keep on getting call and land up with no job after 3 months-is that sensible??
go to a 'ok' college and u develop lots of skill.u get one call and u get the job-that is a foolish thing to do?(according to you).

college is not spoonfeeding like u were done in ur school.it's all about developing skill,ur life ,ur personality and learning the way how to run it.and i believe learning how to make ur career or make ur living does not need a fancy college.
may be u sud do your research on this part ,time pass.
