I'm waiting...

The worst part of job searching is the waiting. First, you find that job posting and you submit your application. Then, you wait. You wait for someone to respond and tell you that they've received the application - sometimes that doesn't even happen. Then, let's say you get an interview. You have your interview, then you wait again. You're waiting for them to contact your references or let you know whether or not you're going on to the next round. If that happens, there's more waiting before an offer may come your way.
This waiting can be a few days, a few weeks or months. You never know. You don't know if offers have been made to someone else or if they're just running behind with the process. You don't know if you should start applying for other jobs. Yes, you can e-mail/call and ask where you're at in the process, but you don't want to be that annoying candidate who calls every few days. So you wait....
