Getting a job is hard work, but losing one is easy. At least, it was for the people mentioned on this list — they screwed up so badly in a job interview that they lost the job before they even got hired.
Someone asked HR managers and job recruiters of Reddit: "what is an instant 'Well, this person isn't getting the job' thing a candidate can do during a job interview for you?"

Had a guy who was a little rough but was looking quite promising for a design role. He blew it with me by saying “I’ll turn this company around in 6 weeks” and a few more comments along those lines with a theme of “you are currently messing it up”.
This is a small successful company. I wanted him to fit in, not “turn us round”.
