It was an internal job application (advertised with the University only) and it took only about 2 weeks from the application deadline to the job offer which is very fast for academia. The interview was only 15 min and very much on the job questions. Easy in my case because I haev a lot of experience with the techniques that were asked for in the job advert. However, anybody with less experience would be able to answer the questions with a little bit of preparation before the interview.
