As you approach a job interview, you are going to be given the chance in your interview to ask questions of the employer. What are you going to ask? What do you really want to know about your target organization that can't be found on their website? And how can your question provide your potential employer with the idea that you have done your homework and are legitimately asking a question to gain more insight into the organization?
First, homework, homework, homework. You have to approach "getting a job" like it is your job. When you are offered that precious interview, make sure that you know all you can know about the company before you enter their front door. Second, don't ask questions that you can find on the internet. That indicates that you didn't care enough about the job to read about the company. And third, make sure you have at least one question prepared. There is no way that your interviewer will be able to tell you everything that you want to know about the company. One key attribute that prior military bring to corporate America is their leadership experience - ask about the company's leadership training. Ask how the company prepares their front line leaders to assume greater levels of responsibility and ask how you would fit in their leadership development based on the position up for hire.
And, again, do your homework before you go for the interview. Good luck!
