I applied online. I interviewed at Solactive (Berlin)
Interview
One typical question which can be easily found on the internet. They are not looking to hire you but they are looking at improvements to their existing system without paying you in the form of interview tasks. Do not waste your time and look for a better company. A very junior person interviewing a senior person doesn't makes sense at all. They don't want good coders but they want some working specifically only in Java and Testing.
