I applied online. The process took 6 days. I interviewed at Block in Sept 2015
Interview
Starts off with a coding challenge online through hackerrank. you have 2 hours for 2 problems. The problems, in hind site, were not very difficult but with no external help (Google) really allowed the little things that you don't remember off of the top of your head can trip you up.

The interviewer was nice, and he is friendly and willing to give hint, the question has 2 follow-ups, it was hard to complete in time. The question was not a typical LeetCode
