Bloomberg Software Developer interview questions

The role was initially described as C# / WPF, and F# expert - I did not claim to be expert in any of these - for a trading solution connectivity and integration software platform. The interview was via HackerRank, with the primary interview held over phone, while the interviewer could share coding with me via HackerRank. Initially for one hour, asked to solve code solutions for questions in C#

An internet site called hacker rank was used. The phone process was a bit difficult because of the background noise. There was a bit of confusion because of this and the person conducting the interview was not completely used to the site.
