Online application through company website. They get back to me after approximately 4 weeks, asked if I'm still interested in the position and scheduled a quick telephone screening interview. After that it went quite quickly, I was invited for a face to face interview with my potential future boss for the following week. There were no difficult or unexpected questions during the interview, just casual interview questions, why I am interested in the company and job, what is my background, where I see myself in the future, why did I choose my field of study and similar. I was told in further detail, what responsibilities and tasks are to be expected in the role.
There were no other rounds, I got the job offer right the next day after the face to face interview.
