It was a very clear and short process. Job description was clear and they explained every step with details. I talked with HR first and then with my current manager.

3 stages. 1st was HR, 2nd was hiring manager, 3rd was the boss of the department. First was quite typical, they just want to hear that you will be a student for at least another year and you have experience in the field. 2nd they ask role specific questions. 3rd was just a final check-in.
