Long process, small test, then short phone call with easy questions. They required 8 hours of test. I thought it will be okay with all the previous question but in fact they asked to build literally entire trading user interface with order book and order history just within 8 hours without knowing terminology and so on. It was a complete waste of time and totally unserious. I don't know who they look for. The other developers judging by their history are not so advanced. If you want to try, ask money for that test, don't make my mistake doing it for free.
