Q. I am looking to reenter the job market after being a stay-at-home mom for five years. My problem is that I don’t know which jobs I should target. I worked construction before I left the job market. I am 47 years old and haven’t been on an interview for over 15 years. I need resources to help me interview, write my resume, and find the right job.

A. Welcome to the job market of today, which has changed immensely since your last visit. Technology has had a serious impact on how to go about a job search, and some basics can help you get started.
