Continental interview questions

First I was invited to the company facilities by the HR department to attend a general interview and solve an exam of technical knowledge, after 3 or 4 weeks I had a phone interview with would be my administrative boss, I made both personal and professional questions based on the resume I had sent, also he explained to me the job responsibilities, then I had a phone interview with the discipline manager and a future colleague, it was more technical we talked in detail of my previous projects, finally I get a personal interview with the R&D manager, here is when I got the job offer and a facilities tour.
