Bloomberg Full Time Software Developer interview questions

I applied in CDW of campus and got on campus interview one day after. The interview process last 50 minutes and there are 2 interviews. Both of them are nice and give helpful hints if you're stucked. At the beginning they asked what other companies I applied and why Bloomberg. then they asked several C++ questions and 2 algorithms questions.

Applied online through career website, Selected for campus interview. Two interviewers took the first round. Supposed to 45 mins interview but they took it for 1 hour 15 mins. Asked about resume and from there asked about memory optimization, word padding. Gave struct with int and bool in it and asked me to optimize the size of it. Later asked to write code on tree traversing which was easy. But grilled lot on Memory optimization, which i was not really prepare for!
