All in all, I had 7 interviews, about half of which tested my knowledge and skills. I was given freedom and flexibility in choosing the time and days of the interviews, and the process took about 7 weeks, from the first contact to the offer. The interviewers were always on time, very respectful, and friendly. They were competent and put me at ease. I was given instructions on what I should prepare, and the questions, while difficult, were what I expected. As a downside, the process was pretty long and exhausting, especially the interviews about my work and education, where I had to detail every job I've had. I suppose that gets even more tedious the more experience you have.
