Alright, I have a question for you. Working on your resume – want to know what a smoothie maker is professionally called – but not sure if it has anything to do with food? Is it really relevant to your resume? A smoothie maker can be the blender type device used to make smoothies or the person using said equipment. If you’re talking about the person, it’s called a catering professional in charge of making cold drinks. The beverage specialist works too 🙂 If you’re applying for a job in the restaurant industry, unless it’s a very upscale place, they won’t expect an extremely high level of formality as long as you’re professional when interviewing.
