I caught their attention when they came to my campus for an on-site career fair. Their phone interview wasn't too difficult either - there weren't any coding questions.
However, the more annoying part of their interview process came a little afterwards. Some of the few things that bothered me the most was that they wanted my high school GPA and my ACT / SAT score.... which wouldn't bother me so much if I wasn't in college already.
Their online assessment wasn't any better either. The math portion of the online assessment made me feel even more insulted; it seemed to be annoying algebra or word questions people would ask middle schoolers.
However, once those were over, the on site interview was fantastic. They made me feel extremely welcome, and I can definitely tell it's one of the best places to work at.
