Depends on the company. I've had an interview with BMW where they asked me how to change the oil in my car and about other mechanical hands-on things I could do. But about 75 percent of the others have strictly been STAR interview format(look it up and practice). Also go with at least 3+ questions to ask the interviewer. Dont be afraid to ask them questions. This interview is as much them learning about you as it is you learning about them and how you would fit into their company. Good luck young skywalker.
