The „rules“:
● You may ask the moderator questions about the project
● You must be prepared to present a rough architectural vision
● You may make assumptions about technlogies you don‘t know
● You may not assume hiring/firing authority for the developers
● You can use any technology you want
● You may ask about any other rules
