Call back for second interview?

its best to call. then they will know u are really interested in working for them but its best to call early in the morning. just say that u want to know the status of where u stand. u already got one interview down obviously they are interested i don't see any harm in calling. i had an interview they say they would call me back i regret not calling because they probably thought i didn't want the job as bad. people always want motivated people who really want to work. so i say give them a call and good luck!
