I applied online. The process took 1+ week. I interviewed at Frequentis Comsoft (Karlsruhe, Baden-Württemberg) in Mar 2019
Interview
One interview with Hr, teamlead and a manager.
It went well, i could guess in the interview that they were positive.
There was just two small technical questions but not difficult. But also i joined after 7 years of experience.
Another colleague had it more difficult, may be because he had no experience before.
The reply came just next working day.
Interview questions [1]
Question 1
Small main function and question about which algorithm and the optimum way to sort/search in array.
