LinkedIn Software Developer interview questions

I was contacted by a recruiter and we had an informal chat about LinkedIn and what i am looking for. He was very relaxed and explained in detail. I just had my first interview. I am waiting for feedback and hopefully tons of interviews. public interface PointsOnAPlane { /** * Stores a given point in an internal data structure */ void addPoint(Point point); /** * For given 'center' point returns a subset of 'm' stored points that are * closer to the center than others. * * E.g. Stored: (0, 1) (0, 2) (0, 3) (0, 4) (0, 5) * * findNearest(new Point(0, 0), 3) -> (0, 1), (0, 2), (0, 3) */ Collection<Point> findNearest(Point center, int m); }
