Research on the company and sales
Be yourself and be talkative.
I wouldn’t bother going but if you are really stuck, research into the company. Emphasise on the fact you are reliable, self motivated, goal driven.
My advice would be to not go, but if you must. Research into the background of the company. Come across self motivation. List off that you are target driven, reliable, and all those positive key words and you will more than likely get the job.
Help jobseekers learn about the company by being objective and to the point.
