I was already working for the same company on a diffrent position when I applied for this one. I already knew the company values and what kind of employes they preffer.
I should start with the fact that I really wanted the job and I was convinced that I can do it. Before the interview I took a 3 days internship on the position - this proved my interest for the job.
There were 2 interviews: on both of them they put me in different situations to see how I react and how confident I am with taking decisions an assuming responsability.
