internship application

Hi,

For application for internship at ZIBA, they want to see works samples including sketching, process demonstration, concept generation and computer skills. How to show them “process demonstration” and “concept generation”?

they probably want to see that yo can develop multiple solutions on a project through sketching : i.e. concept generation

and they most likely want to see your thought process through thumbnail sketches, concept sketches, then refined sketches, renderings, control drawings and finally models: i.e. process demonstration
