Bloomberg Software Developer interview questions

I was referred by my friend. After about one week, somebody reached me to set up a phone interview. In the interview, everything is about the concept of C++ as well as some networking concept and how media transfer in the network. First, just talked about the data structure, like which one you prefer. Then, so many C++ concept. Finally, asked about networking and media. So strange compared with the previous interview.

Got a call immediately after job fair and had 2 rounds of technical rounds. They were quire easy. Generally every round has a design question and a coding question. 2 persons were interviewing me.
