Seriously. Look, not everyone interviews well (meaning on the hiring side), so take this with a grain of salt, but: if you can’t get a single person in the interview process to crack a smile, why in the hell would you want to work there?? The interview’s for you, dummy – they’d be lucky to have you. The next time you walk into an interview, remember, remember, the 5th of November (err, wait, that’s me advising you to blow up a building. Don’t do that.) No, remember this instead: they want to hire you. I swear to it. They’re praying that you’re the right person for the job.
So if they give you attitude about how lucky you are to be there, or act like you’re a duck among camels, don’t take the job. You can do better.
