Applied online and received an email about two weeks later with an invitation for a pre-screening programming aptitude test through HackerRank. The problem was to parse a binary file containing trade information exchanges and extract various information from it. It was pretty easy but somewhat time consuming. I did get 72 hours to complete the task and it probably took me about 5 hours total with testing and everything. Make sure your code compiles and runs on Linux! I received an invitation for a phone screen a week later. The phone screen lasted about 45 min and was mostly a conceptual discussion about C++ with special focus on C++11. HR set up a codepair on HackerRank but the interviewer did not want to use it so there was no coding involved.The conversation was actually a bit awkward but it was otherwise fair. I received a timely email two days later stating that they wont continue my candidacy. Overall fair process and reasonable timely rejection notice.
