Bloomberg Software Engineer interview questions

Went on campus for an interview, was asked alot of Data structure questions about linked lists, stacks, queues, binary search trees, hash tables, Initially we started with the standard tell us about projects youve done. Then on to two techincal whiteboard coding questions, First one was rotating a matrix and second one was to find min element in stack. Overall it was not super hard

I had an interview on campus. The interviewer was friendly. It started with questions about my resume and then moved on to two technical questions. One was about trees and other was a design question.
