Bloomberg Intern interview questions

I have applied via careers.bloomberg.com website. After CV screening I had a phone interview. Questions were very basic: difference between array and list, what is polymorhpism, difference between C++ and Java. Interviewer claimed that methods in Java are not virtual unless you explicitly use virtual modifier (!). 30 minutes later I received an e-mail with invitation for in-house interview. In London I had one 2:1 interview, questions covered data structures, memory management in Linux (I had linux kernel development exp in my resume), some brain teasers.
