Show up for job interview 15 minutes early. Interviewer is over an hour late. I left. Doesn't even apologize the same day. Instead, he e-mails me the next day pleading for another chance. I didn't respond.

I work at a small startup. The dude that hired me is notorious for being late. We had a few interviews like that before I decided to handle all the developer related interviews. My first day of work, I showed up and no one was there. Damn Internet marketers and their 'work at home' lifestyles.

Glad I stuck with it though. I'm making the most money I've made in my life currently.
