The qualifications to get a food sales job start with a high school diploma or GED certificate. You can start many sales jobs with just a diploma, although previous experience in retail stores or restaurants is often useful. To move up in food sales, you may need to have several years of sales experience or an associate or bachelor’s degree in business administration. In addition to these qualifications, you need to have excellent interpersonal and negotiating skills, good analytical problem-solving skills, and the ability to travel for work.
