I applied online. The process took 5 weeks. I interviewed at Philipp und Keuntje (Hamburg) in Sept 2015
Interview
It was a little longer than expected but nice from the point that they really want to know the people they hire and I think that is good to consider. They are all nice to talk to and you can feel a good environment among the interviewers
Interview questions [1]
Question 1
