Only one interwiev. It was nothing special, no extraordinary questions. It took only about 1 hour. Mainly they were interested about why whould like to work there and how many hours I can do next to my studies. They expected more than what they wrote in the job description, so it was one of the biggest reason why I did not get the position. Also it was disappointing that first thing what they mentioned, that they are team is full, only they need a trainee until it is a trainee, after that they might have some other position somewhere else at the company. It was really demotivating.
