You never want to come across like an over-rehearsed robot when you're interviewing for a job, but that doesn't mean you shouldn't practice. Quite the contrary. Outlining answers for predictable interview questions is crucial to your confidence, which is an attractive quality in job candidates. Applicant pools are larger than ever, so take your typical interview preparation a step further by visually critiquing your pre-performance.
Ask a friend to stand-in as your interviewer, and once you get past the initial giggling, the exercise can prove to be highly valuable. You may be surprised to find that you fidget with your fingers, nervously shake your leg or tap your foot, or play with your hair unknowingly. Polish your act by fixing your on-screen tics so you'll be all set when it's game time.
