I like tennis. Started learning it as a teenager with my dad. There was one thing in particular I noticed as we practiced and my shots and volleys got wilder or more controlled and purposeful. It was my feet. When I was moving my feet about trying to get into position and then moving again and shifting (I began to call it "waffling"), my shots had little accuracy. I'd lose the volley. But when I firmly planted my feet and stood in solid, square position, my shots went exactly where I wanted and I'd win the point.
Many times job seekers do the same thing but in regard to the presentation they make. Now the presentation can be multi-dynamic -- body language, voice, inflections, posture, handshake, eye movement and contact. And the presentation comes through in the resume and correspondence. But let's deal with the physical today. Anyway, there's a parallel between solidly planted feet while playing tennis and making a lasting, good impression during the job search. It's part of gaining the point.
The thing that wins anyone over is a positive, self assured attitude. When you go into any type of encounter, stand straight, square your shoulders, look the other person in the eye. Looking down at your feet or askance says you're trying to hide something or you're really weak. Either way, it isn't giving a good impression. Being self confident conveys itself as competent.
Let's say you're asked a question or asked to take a stance on some topic. What the interviewer wants is to see how well you can talk about the subject. If you have expertise in the area, this is your time to show off and go into some detail. The best way to drive the interviewer up a wall is to take first one stance and then backpedal while trying to figure out what they want to hear. Don't waffle! It isn't necessary to please people. What is necessary is to take a stance and be able to follow up on that stance with reasonable, well-founded, supporting statements.
Going into an interview, conducting a job search, meeting other people is sort of like playing tennis. The more you let your feet dance around, the more you waffle, the less likely you're going to make your point. But when you stand solid, when you're sure-footed with feet planted and squared, looking directly at your target, the more confident you'll appear and the more your shot will go exactly where you want it.
