I get it, traffic sucks. But unless you have a DeLorean (see eBay) to travel back in time and leave 15 minutes earlier, chances are you'll limit your chances of getting the job by being late. Whoever said "better late than never" wasn't referring to job interviews, they were talking about visiting the in-laws.
It's a job interview, not a wedding. Research the company ahead of time to make sure you don't dress like you're going to the Academy Awards when you're interviewing at a fast food joint. Someone serving you fries in a tuxedo, weird.
Umm no. Keep the paper white. This isn't Legally Blonde and you're not as pretty as Reese Witherspoon. But your clever pink resume would really brighten up the trashcan at the office you're applying to.
"Hey, you talkin' to me? You talkin' to me? Then who the hell else are you talking to?!" Be polite to the people you interview with because chances are they may become your co-workers. And you never know what someone might do.
It's okay to look up his LinkedIn or Google his name to see if he actually exists, but if you're bringing up what movie he saw last week or referencing his status updates chances are you're going to come off stalker-y.
"I'mma let you finish, but I'm qualified for this job so stop telling me about it." Sometimes the best thing to do is listen. When you finally get the job, then you can interrupt your boss or demand employee of the month.
"Show me the money!" Yeah, I know you want cold hard cash, but if all you want to talk about is how many benjamins you'll get each week they might think you're only in it for the paycheck. (It's okay, we know you are, just don't say anything)
Okay, so this is technically after the job interview, but if you somehow did everything above and by some mysterious chance you didn't get the job, don't troll the person. It's not personal (Except when it is). But if you're really upset, there's a website called Poop Senders that will literally send fresh turds to people. If you're going to be bitter, at least do it right.
