You've Hit the Ceiling at Entry Level
The manager thinks you'd be the perfect person to file paperwork and answer phones. Where will you go after you've mastered the art of this entry-level job? Nowhere.
An important question to ask during the interview is some variation of, "Where do I go from here?" Does the job offer any upward mobility? Will they train you for a management position, or leave you stuck on the bottom? If the glass ceiling is on the ground floor, you could toil away for years without any sort of promotion or pay raise.
You want a job that will challenge rather than bore you, and offer plenty of room for growth. If you can set your sights on the president's office without getting discouraged by management, you're in the right place.
