Real-time, web based REPL for programmer screening


Very interesting code/compiler site. It’s obviously in an initial state, and no documentation, but still quite impressive.


Choosing Java, it creates a hello world app. Then, you can create other classes in the same ‘file’, and it will compile them. Shows results of execution (assumes a static main method).

It’s target is for evaluating programmers using a real compiler, and therefore more realistic than whiteboard/paper/text editor tests.
