Intuitive Mechanical Engineer II interview questions

Just did the first screening interview. The interviewer was very blunt and direct, immediately jumping into the company's interview process, which is as follows: (1) short 30-minute screening interview; (2) one hour technical interview; (3) half a dozen interviews with other coworkers/team members; (4) and offer letter/decision. I was asked to present or explain examples of my work that show my technical proficiency in the relevant areas.
