Cboe Software Engineer Intern interview questions

Started with an introductory interview with the principal software developer, then a second round with other members of the team. The second round had some technical questions about data structures and C++ syntax. Some of the members were not interested in the interview, but the Principle Software Developer was very nice and engaging.

First step was a phone interview. Just to get to know you / get some background on you. After that was asked to do a coding challenge. Sent it in and never heard back.
