Being 55 when I graduate with my Bachelors in Human Resource Management what is the likelihood of getting hired within a reasonable time frame?

In the SF bay area many HR professionals have advanced degrees. To get hired in a short time frame I would be looking at internships and support positions. Check out all the opportunities in HR and see what one interest you the most. There are positions in compensation, benefits, disability, etc. Compensation, for instance is usually staffed with employees who enjoy math and determining pay scales for positions new and old as the economy changes. Once you have a year plus working in the field you will have a better idea of where you belong.

Being older with years of experience in the Navy is a big advantage. Employees often complained that younger HR professionals didn't have enough life experience to be able to really understand their issues. In HR is a positive.

First and foremost, thank you for your service. Next, companies don't discriminate based on age. That being said, getting some foundational experience and knowledge such as education is great. Getting the practical experience at the ground level will help you move up as well. Good luck!

Many companies look for veterans to hire because of your experience. Getting hired with the right company depends on what you're looking to do for a career.
