Behavioral phone screen followed by a HackerRank code challenge. Then two more phone screens. Then an on-site interview (which I could not attend, so we used Google Hangouts instead). The on-site consisted of an initial programming question where we talked through a solution. A solid understanding of basic data structures and algorithms was required for this question. It was not "how does this data structure work?", rather it tested my ability to use data structures to solve a problem. Then I had to actually write code. I had to write a fairly simple command line program. I was given around 45 minutes and solved it with a little bit of time left over. Then I spoke with a PM/scrum leader. He was really nice and we talked about the work at JW Player. It seemed very interesting and challenging. Finally, I had one more challenge that involved a rather advanced/esoteric data structure. I knew the solution, but had never implemented it before, so I had to work through it with the interviewers. In the end I was able to solve it correctly.
