Employers: “Please arrive at least 10 minutes before your interview, I don't care what reason you have or what emergencies come up, if you're not at least 10 minutes early, you're unreliable and rejected.”
Also employers: “Sorry mate, accidentally scheduled a meeting exactly when your interview was supposed to happen, ain't that a bitch! If you could just wait around for at least another 45 minutes, that'd be great!”
I'm at my place of interview right now, wondering why I haven't been called through yet, and the 45 minute example I gave above is not an exaggeration. Interviews are already nerve wracking as hell, and you're gonna make me sit around and wait for you.
