Began with a phone interview with the hiring manager that lasted approximately half an hour. I was asked mostly questions about my resume and past experience. The next week I had an in person interview in Buffalo Grove, IL where I sat down with the hiring manager, her supervisor and a manager from quality. Each person interviewed me seperatley for about 30 minutes each. A week later was a 2nd in person interview to recieve a tour and meet with another engineer on a similar level to ask questions.
