Welcome to the boards. I am an ID manager working at Mars Chocolate US.
Fig - As mentioned above there is quite a bit of design in the confection world. I am responsible for managing the design of the moulds, but seasonal and everyday moulds, but also the evaluation of the consumer and making sure that the product is delivering the proper sensorial experience. This includes the mould, pack, and every other touch point that might be relevant.
We still do A LOT of sketching. then moving to CAD and prototyping.
