What is your overall career objective? Do you see yourself working in engineering ten years from now? If not, what do you think you will be doing?

Most engineering firms realize that if they hire you, there's a 50-50 chance you'll still be there in ten years, but it is still important for them to know your personal career goals before they bring you on board. This is especially true for mid-level and upper-level professionals. For example, if you aspire to be a senior vice president of an engineering firm and the firm you're interviewing with doesn't envision having an opening for you, then it may not be a good long-term fit.
