CV screening Can send you a task if they see that you don't have enough technical background Invite to 1st interview - logical tasks, questions about IT (active directory, servers ect) + short talk with hiring manager After that can sen you another tech task to write bugs and test program After this - final interview with 3 hiring manager

I think Interview process was just a formality, selection based on IT Qualification. May be, I don't have required IT skills according to them as I came from mechanical background.
