Bloomberg Financial Software Developer interview questions

asked me Qs on Java and den gradually making it into c++, trees, datastructure,

I applied and received an online test via email the next day. After completing the test (presuming you pass) they schedule a phone interview. This consisted of a couple of brain teaser question such as implementing a stack using 2 queues and a couple of others. After that is the onsite interview. The interviewers were nice but I bombed it anyways. The first question asked how to convert the base of a number. There were also a couple of questions about trees.
