If you want to rock a job interview, don't just sell yourself and your abilities. Sell how you're a great fit for the company in terms of personality. And smile.
A study published in the American Psychological Association analyzes two interviewing tactics side-by-side: self-promotion and ingratiation, which means working to be liked by others.
The results suggest that job candidates who focus on ingratiation, or who were likable, have a better chance of being hired.
If they are perceived as a good fit, their chances for landing the job rise even more.
Self-promotion, on the other hand, has only a weak or limited impact on hiring results.
