As you are looking for a job and getting beyond the applying online route and are actually talking to real people, you may find yourself panicking. You have to talk to real people and you do not know how to do it! How do you carry on a conversation? How do you gauge what kind of impression you make on others? How do you answer even basic questions about who you are?
There are several solutions besides the one of not doing anything. You can pay lots of money to a professional coach and take lots of public speaking classes.
But if you are on a tight budget and cannot afford any of these solutions, there is a rather inexpensive and fun way to develop your skills at speaking in front of and to others: The answer is (drum roll please) Toastmasters. They can be found at http://www.toastmasters.org/
Or, if you are local to Oregon, try this URL, http://reports.toastmasters.org/findaclub/searchresults.cfm?Country=United%20States&State=Oregon
Why would joining an organization, which forces you to get up and speak before others be good for me, if the job I am searching after doesn’t require me to do a lot of speaking? Well, even in IT shops, where I have toiled for years, you have to present information to colleagues and bosses in an organized manner. You have to talk to people who do not share your background and expertise, and get them to understand what it is you are trying to do. You generally have to go through an interview in which you want to present your best self. What better place to learn all of these skills for a very small amount of money.
I speak from personal experience. Most Toastmaster clubs are filled with supportive people who help each other develop their abilities presenting their best selves in front of others. Even though I have spoken in public many times, and taught school for many years, there are still many valuable things I have learned from my club; how to run a meeting, how to be a better listener, how to think on my feet.
Besides that, Toastmasters can be a lot of fun. You get to meet interesting people and who knows, one of them might know of an opportunity for you. Ya never know.
