Foobar is a semi-secret hiring challenge Google put out there to find talented developers. Foobar is a series of five levels of algorithmic questions of ever-increasing difficulty and allotted time to solve these questions. Once the developer requests a question, the clock starts ticking. For every problem, you can either submit a solution written in Python (2.7) or Java. Before submitting, you can also validate your solution and run it against a suite of secret tests.
What is cool about Foobar is that it takes place on a virtual server, to which you gain access once invited into the challenge.
