I applied through a staffing agency. I interviewed at APPSfactory (Leipzig)
Interview
The interview took a pretty long time. It consisted of an HR interview, a 1 hour technical interview (pretty standard theoretical questions), a home project (3 weeks) , an 8 hour "workday" experience and a short call with the COO.
