So you had a great interview. The offer is on the table. You are ready to sign on the dotted line. Not so fast.
Employers are not always up front about the job and/or school that they may be hiring for. I once had a principal flat out lie to me during an interview just to get me there because school was starting two days later. Don't always believe everything you hear.
Do your research. Find out about a school/area before you commit. Nothing wrong with asking for a day to think about a job offer to get your thoughts together.
