First conversation is getting to know you, looking at your portfolio, and asking some high-level concept questions about how you'd handle some common workplace situations (such as something goes wrong during a project or with a client). Generally friendly and conversational process. Next round is a CAD test to determine basic SolidWorks understanding and a brainstorming exercise to showcase your creativity and problem-solving skills. Much effort is spent to determine fit with the team - you'll meet all the employees.
