1. Lying
About two-thirds (69%) of hiring managers said fibbing is an instant deal-breaker.
If they catch you in a lie, they'll assume you're a dishonest person. Who wants to hire someone you can't trust?
2. Answering a cell phone or text during the interview
About 68% said this would prevent them from offering someone a job.
It's incredibly rude and unprofessional — and unless it's an emergency, picking up your phone during the interview tells the hiring manager you're easily distracted and not 100% focused or engaged in the conversation. It may also tell them you don't really want to be there.
3. Appearing arrogant or entitled
About 60% of people cited arrogance as a deal-breaker.
If the interviewer gets the sense that you're a pompous narcissist, they'll understandably have reservations about bringing you on as an employee and subjecting other employees to your selfish behavior.
4. Dressing inappropriately
A whopping 50% said inappropriate clothing would make them not want to offer a candidate the job.
"What you choose to wear communicates a lot about who you are and how you see yourself," writes former Business Insider reporter Vivian Giang.
It's important to dress for the job you want and to always maintain a professional look — especially during a job interview.
5. Swearing
Half (50%) said they wouldn't hire someone who swears during the interview.
Career expert and author of "The Humor Advantage" Michael Kerr previously told Business Insider: "As obvious as this may be, don't use curse words or slang terms in an effort to come across as 'authentic.' You'll only give the impression that you have poor communication skills."
