Pen is Important sometimes like in class or work. Before interview for a job, the first they will ask you to do is fill in the job application. They will ask to 'Do you have a pen to fill in the form?'. If your pen is ever ready in your bag then your first impression is looking good to them. Everyone knows that you need to fill in forms if you're job hunting. So don't forget to have a pen with you. And ready a note book just in case you want to take some notes.
