In preparation for an interview, come ready to discuss your portfolio at length as well as your design process and what design software you are familiar with. Graphic design positions can be very specific to the company so make sure you brush up on the company's current design style and are ready to explain how your style and experience will mesh.
What are your views on over-timing and late hours to meet deadlines?
I value deadlines and believe work must be done in time. But I am also a family person, a mother, and it requires me to be at home to take care of other responsibilities at a certain time usually after 6pm. I do not mind taking work home beyond usual working hours and making sure that the deadline is met at any cost.
It's because she doesn't have a family at all. I am happy you dodge that bullet.
