Even the a company does reject you, most of the time they should email you back saying you didn't get the job._DeathlessOne_ said:Only email them if they give you an email address and ask you to.
Your most likely not getting anything back (if your emailing them through the careerone website) because they probably havent asked you to email them, and they havent bothered to check their email/whetever.
Either that, or maybe your applications just plain ol' suck
