I'm a new grad, I sent them a CV and after two phone interviews I was flown in for a day of technical tests at the Newton Offices. The two phone interviews were fairly straight forward, one of which was to implement StringBuilder in Java, rigorous on site interviews in which i talked to 6 different people, each of which made me solve whiteboard problems. Overall positive experience, fast replies and generally fast process. They focus on the computer science core so brush up on algorithms and data structures.
