Certain key phrases mentioned during a job interview will clue you in that you're soon going to be sacrificing your life to the company.

Find out in advance what kinds of hours you'll be required to work in the job. If you can expect to spend long nights and weekends at the office, really consider whether the job is worth your health -- and sanity.
