8. Low energy or passion

Passion + energy = good impression.

Managers want to hire people who are enthusiastic. It doesn't matter how boring you think your last job was, you can still be passionate about your work, and you need to get that across in your interviews.

Don't speak negatively about your former duties, boss, or company. Put a positive spin on the situation and your job search. This is particularly important for people who have been in the job hunt for a long time or who left their past employers under strained circumstances.
