Here are nine tips to instantly set yourself apart from everyone else, and show the hiring manager that you are the best candidate for the job, that have nothing to do with your resume.
I've never said no to a candidate who overdressed for the interview. You don't necessarily need to wear a full suit. Use your best judgment. Know what's expected of you in your line of work. When in doubt, wear something more formal rather than less formal.
A trick I always use in interviews is to carry a notebook. I rarely wrote in the notebook, but bringing it with me to the interview still conveyed a sense of professionalism and organization that impressed many hiring managers.
Smiling during the interview will immediately give you the upper hand in a sea of average candidates. Make the interviewers believe that you want to be there.
If the job requires particular skills, confidently talk about your experience with those things. Discuss the most important elements of the job you're interviewing for.
