I understand Square/Matasano ran it to hire people at the time - could anyone tell me if having completed it means I can be considered able to do a job in the field, and someone worth hiring? Or is the CTF just an introduction to the field? I have been doing a lot of learning since, and understand there is a vast (and endlessly fascinating) amount to learn beyond what's in the CTF - but what level do I need to be at before I consider applying for jobs? I remember reading that Matasano used to send candidates books to read and learn from as part of the interview process (which just sounds like my dream company) - as someone who would happily learn whatever it takes during the interview process and on the job, what level do I need to be at before I even consider applying?
