Bloomberg interview questions

I talked to Bloomberg recruiters at a career fair at my school, and they suggested a position for me to apply online. They were at my school looking for undergrads, and I'm a soon-to-be PhD. I applied online. Response was quick... a little too quick. I was in the airport, and they immediately sent a link to a timed online screening. I had to ask for postponement which they kindly granted. The screening was simple. Two tests, each around 45 minutes long, multiple choice, with various questions about the details of C and C++ syntax and semantics. A week later, the first phone interview. A week after that, second phone interview. Two weeks after that, fly in for two days of in-house interviews. Interviews featured questions primarily on C++ semantics, C++ STL (Bloomberg publishes their own implementation on GitHub), networking, and concurrency. There were a couple of brain teasers. Interviewers were nice, dressed primarily in polos or untucked shirts and jeans (I felt overdressed in a suit). Interviews on the first day lasted from 10am to around 4pm with no breaks, and I met mostly project leaders. Interviews on the second day were from 2pm to 5pm, with senior management and HR at the end.

Drop resume at university career fair, schedule an one-week-later school campus interview right on the career fair after chatting with the representatives; the second week, 2 rounds interviews with 2 Bloomberg employees each in the same time, all technique questions; then got an invitation for an on-site interview with a technique manager, followed up by an HR representative. The onsite interview is technique too, they also ask why you want to work here and show you Bloomberg terminal. Got an offer a week later.
