Hudson River Trading Software Engineer(Internship) interview questions

It was fine, I had a C++ implementation question. The main issue was debugging in that fast of a time slot. I would recommend speedily writing code. Also the OA was Leetcode Mediums.

Started with an OA, (which I believed was not automatic). Then, proceeded to two phone screening rounds, which tested on general C++ programming, and then got grilled on C++ fundamentals and how computers work under the hood. Got into the superday, which is onsite and has 3 total rounds. Didn't make it past second round, but they are all live coding. Be prepared for heavy implementation style questions, and talk through the design of the algorithms and data structures you use.
